I did an acrylic tank about a year ago using a head light kit. It was scratched very deep like yours. My kit had sand paper disc 600 grit to 3000 grit as well as the polishing wheel and final compound you showed. I spent about two hours a day for 6 days working on it. Looks like new and only had $24.00 in the head light kit. Only precaution I took was rinsing the tank very well with water and dawn dish washing liquid, after I was finished. Tank has been up and running for about eight months, no problems what so ever. Thanks for sharing!!

Dude, what a great result... so very well worth watching. Thank you for doing this. 10 on a scale of 1-10!

Thanks for sharing the info on how to get scratches out of your aquarium. I got all the scratches on my aquarium with the Polish

Hey Zenzo, great score getting a free tank. I can clearly see the difference between the polished side and the other side. I know Paul, The Inventory King, did a big tank last year that came out nice. Otherwise, I’m sure you have some pretty sweet plans for it. A nice display tank down there or a new tank for Oscar would be pretty cool. Thanks for sharing

I enjoy your channel. I have polished out many scratches in motorcycle windshields using a product called Novus. You would need Novus #3 move to #2 and finish with #1.

Not "perfect" but a thousand times better. Even after a good rinse, I suggest you use a big bag of charcoal for a few weeks prior to introducing fish to pick up residual. Nice tip, thanks!

Wow! The difference is clear. (No pun intended) Great tip!

Looks good. My 125 got pretty scratched up in storage and I'm going to try to fix it myself. I paid $300.00 previously to have it done professionally but I'm willing to give this a shot and save some Bill's this time. Thanks for the vid.

That looks awesome! Your DIY videos are great. I have been wondering how well acrylic could be reconditioned.

Awesome tip!!

Nice Tip! I did the same on my acrylic but used Novus from amazon $20 bucks 3 step worked wonders and had tank looking like new.

I've used Mother's automotive polishing compound on glass. Works wonders and is safe after a good rinse. I don't know how it would do on acrylic, though...

Knowledge...I love learning new things

Thank you, such great information,

Nice Zenzo. I remember do this on my 220. Big job!

Helpful video! Thank you!

I like this guy, similar interests, fish guy, DIY car guy, and a niners fan. Hell yeah!

They sell buffer compound that’s made for acrylic fishtanks that does pretty much the same thing, just be careful and keep the buffer moving evenly, if you stay in one place it’s making that acrylic much thinner and if you overdo it you can actually make weak points that will pop or crack. Looks good.

Once you fill it up with water it will look perfect. The water will fill in any little imperfections from the light reflecting on the scratches.

Awesome man, just restored my caravan windows thanks to this video. Thanks heaps!

Looks good

That's awesome!

Excellent! I don't have any acrylic tanks, but my headlights need polishing - LOL 💕👍

Amazing!

This week I again sanded the 240 with fish in it as I drained for a water change..and YES, The 3000 grit sandpaper ( feels more like suede than sandpaper) and it works..took out the fine scratches and some of the milky haze old Acrylic tanks get over man years. No damage to fish or plants. I didn't get the whole front pane done..so every week until its as good as it gets. Where I sanded logest? amazing how well it worked. I wrapped the 3000 around a plastic scrubby as used in the kitchen sink..better than the palm of your hand.

Looks great friend !!!!!90 gallons is expensive new

Thank you for sharing. Great info! - Little Bobby

Wow! Way to think outside the box! Thanks for sharing!

I acquired an acrylic 170 gl. that is as bad as that one inside and out. I've been working on it with 3 step novus scratch remover. Effective, but tedious. I'm going to try your method then hit it up with the novus!

I was thinking exactly some when you say the scratches on the glass used Headlight cleaning nice video

Hey great video thabks for the info

3:30 for the product.

I have a bioOrb ex display acrylic tank and it was quite badly scratched up so used bioOrb's own scratch kit its pads act like sandpaper and its pulled all the bigger clusters of scratches out and it looks miles better already i just need to put some more on it redo it with a microfiber cloth to clear out the micro scratches out.

You look fine man, and hey you don’t have to ask us if it’s out kind of video because some viewers will like it and some won’t. Just keep being you and release the content YOU want yo see and produce ❤️ thanks for the help!

Nice video!

Bro you look like tiger woods if he was ripped. Great video by the why.

Huge difference.. With water in, it looks like new!

That's pretty good to me. Nice job bro.

That is cool !!!

thanks man that was very good

Nice video, can i use this to clean glass too??

thanks for showing this!!!!!!!!!!!!!!

Good job man.. thanks for video.. I have the same problem to a 130gal ✌🏼🍻

Nice! Thinking out of the box to solve aquarist issues is great! Thanks for the info!

A MAYBE tip: For plastic tanks that are scratched by somebody using a new plate scrubber..the kind with sponge on one side and rough nylon on the other?...on a big tank full of fish? Try 3M 3,000 grit wet dry sandpaper IN the aquarium as you drain water. At the least it removes the fine scratches and some of the "milky" look to an old tank. Now,I just tried a small area..my back is out and I just had to try..but looks improved,fish are fine. I will get back to you on final results. Never give up on old Acrylic tanks...they never leak..so where there is a will there's a way to fix scratches.

Have you compared Novus 3, 2, 1 polish system for acrylic and plexiglass? I'd also be curious if starting with the flame polish would be beneficial or harmful since it's slightly melting the plastic, maybe filling in the deeper scratches a bit. Then for deeper scratches, wet sand paper with increasing grits up to 2000, polish, buff or flame polish at the end? Least this seems to be the consensus I find.. Regarding flame polishing, it seems to increase risk of crazing when welded or exposed to alcohol or other solvents.. so I'd suspect this may create uneven stresses in the material from variable cooling rates..stress induced weakness in a material is not something I'd want in a tank. Don't have a scratched acrylic piece to test on myself, but might buy some.. so curious.

No one should be afraid of scratches on acrylic. They are easy to prevent once you get used to acrylic, and even if you do stratch it, as you demonstrated they are easy to remove. Acrylic tanks split and crack less frequently than glass, unless it is a DIY acrylic.

Your hair looks great

I like it

Awesome Job. The only video I've seen with a clear tank but scratched. I'm about to do this myself on a 135g Acrylic tank that I got for $500. Were there any issues with fish or water perimeters anytime after the buffing? Thanks

Great idea I have the same problems with my acrylic tank. But Is that chemicals safe for adding fish?

Good job brother

If you just get a decent polisher and some decent compound you could cut a lot faster without all that pressure you're putting on your drill. There are some cheaper polishers now days that are decent, HF has a few, also there are some smaller ones you can grab on amazon for 60-100 bucks. For a tank that size well worth the investment imo. Also get some heavier compound, and work your way up to a nice polish. Would get more scratches out and go faster.

Great idea! My hubby's honey-do list just got longer now that I can combine his love for restoring his car headlights with my need for a larger acrylic display tank. I would be worried about the lingering chemicals so look forward to your update on that.

Love your channel. I am to try this technique on my 125g acrylic tank. I’ll post a before and after video on my channel.

How long would you recommend waiting before, in my case, reintroducing a fish. I have some sun bleach on my tank and was thinking id try this to clear up the tank and remove scratches from nieces and nephews.

how many times did you have to rinse/wash out the enclosure before it was safe for fish?

Nice. If you do detailing you must have a DA in your garage. I bet a medium mop and some medium compound followed by finer would get that to display quality. Be careful using a rotary mop as heat will build up. A fine mist of water will help. But you probably know all this lol. One thing I would do is put a balnket down and have the tank on its side save reaching over. Good video and please do not think I am critising....only offering my thoughts on polishing

Thanks for the info. I snagged an aquarium set-up from the dumpster at my apartment and the tank had lot's of scratches and the filter had hard water buildup.

thanks for posting this. looks excellent, def saved me some money. Im actually using this method on my acrylic glass panel on the side of my PC haha

Hey,. Great vid. Should have given a finished effect clip at the end.

You could remove scratches in acrylic with a heat gun...works great as long as you know what your doing.

I wish I would've kept my 55 gallon, looks so much better

Will the chemical be harmful to the live stocks?

Hey man I like the idea but will it harm the fish?

great info - go 49ers!

I recommend making a small sanding block. Start with 1000 grit wet sanding paper. Lightly wet sand. Work your way up to 3000 grit. Use the aquarium grade acrylic polishes. Mothers has waxes and solvents. I would caution using automotive polishes. Anyways you can get that looking new again. Try wet sanding and then polish.

Would this work with Koch polishes

Can you please tell me what products you're using?

Wow

Looks promising 👍👍 certainly not cheap ?

How would you make sure all contaminants are removed. Would you use tester fish first?

My old 240 has a slight haze after 35 years. Must be a billion microscopic scratches. Yet, i set it up and have fish and plants. Now I wish I had known about buffing it out- totally forgot to look for the solution. So,how about using that very fine sandpaper...on a set up tank? Instead of algae scrapping sponges/pads instead use fine wet dry sand paper with every water change? Would that work? Safe for fish?

Should have restored my tank before setting it up lol but i was able to use the rain x kit on the exterior and got good results

Looks perfect to me , Fantastic job thanks

Is it possible to cut acrylic tank to reduce the tank

I am setting up a 300gallon acrylic tank with severums. I would like to add bristlenose plecos to take care of algae. Will they scratch the acrylic?

I just learned from another youtube video that if you use a heat gun you can actually melt the plastic in the scratch until it fills in and make it look brand new.

49ers baby🤙🤙

Is there a magnet scrubber you can use for an acrylic tank.

How did you clean it after to remove the polish?

Impressive. 1 mans junk... another’s treasure

That looks like a clear for life brand

it will be interesting to see if thats fish safe good idea though :D

It looks great but. see down below

So this would work with removing colored acrylic back panels?

I have a glass one that’s been sitting empty in our house for years

hey tazawa, no sanding? I'm breaking my ass off sanding a 120g acrylic, but if you're getting amazing results with no sandingg imma just skip that step lol

Did it work after it dried up

I have 12. Gallon tank eclipses needs be polish scratches out

why are you buffing the inside iof the tank wiouldnt the scratches be on the outside unless you have a partivularly aggressive breed of swordfish

I don't recommend them magnetic cleaners to risky one of our tanks got scratched with one of them

Did you polish inside and out?

that's odd! aren't the scratches outside the tank?

Messing with Corvus could mean Nice big shrimp tank surprises!

no comments say anything about toxic i am pretty sure that stuff is toxic can any one tell me if fish will live in this tank after that i need to buff a tank but i do not no how 66 tall 29 wide 11 deep a so called 91.1 gallon

Bang Bang Niner Gang!

Mothers polish works just the same
