We use the melamine sponge and find it very effective for glass and especially erffective for cleaning acrylic.

I drop a whole sponge into the over-back filter as a water polisher. It traps some of the particulate that is too fine for the regular filter floss to capture,

I have use magic erasers for years because it said it was good for hard water stains. Found out by accident it works great for algae. 46 gal glass bowfront dojo loach tank

You have to be careful now because they now sell other versions that come infused with soap etc.

Magic eraser works great for cleaning tennis shoe soles. They have rehabbed my kids converse’s and made them look like new.

I use Magic Erase on my acrylic tank without problem. They really don’t last very long but clean good.

cool idea and we have used all kind of different things over the years but for the most part don't really clean our glass much because we have a lot of plecos and they really do a great job keeping it clean....

Thank you! Extremely insightful from both a technical and practical stand point!

Seachem sells them as Algae pads so they are safe

I have been using them in my pool filter to help with Algae ..also just started using them in my saltwater tank as a media filter pad !!

Love your native tank and thanks for the video! My daughter in law just gave me some for my tank.

I used the magic erasors with no issues. I now use 7,000 grit emory cloth from Germany. One sheet can be cut into 2" squares that last years each. Expensive but works better. Just my experience.

I love these sponges and haven’t had any issues with them whatsoever. I get the generic ones from Home Depot.

great thank you sir for the clarify.. appreciate it

Per your suggestion, I now have 50 and love what they do!!!

I'm using magic sponge buy from ninso store...at my country Malaysia, cost RM2 or approximately USD0.5... 1 pieces I cut into 4...take 1 of it and use it in my top filter with ceramic ring....change every 2weeks...really does very good job cleaning the water...my plant and fish still healthy till today.. my cost for 2month only USD0.5 for 2ftx1.5ft tank...huhuhu

All I care about is if it's putting micro scratches in the glass. These DO act like sandpaper

I bought 70 of these from amazon after your first video. They work very well cleaning the glass. These do not have soap in them like the name brand ones do. They do fall apart when cleaning things around the house but I don't think anything comes off them while under water cleaning smooth glass.

Thanks

I’ve been using these for 2+ years

I use them and they work great. And I thought I was the only one lol

I love your black striped fish...what are they? I watched your first video...thanks for the followup to reassure the safety issue.

I use a wand that has a large razor blade on it I just cleaned my 20 gal that had algae all over it with no problem. I think it is easier and I don't like to put my hand in the water if I don't have too.

I use the Mr Eraser brand and my sponges actually kind of dissolve when I use them more than once. Maybe the brand you use is a little more durable?

i used a magic eraser inside my acrylic tank and it created a scratchy "haze" that i can't remove! I even purchased a scratch removal kit from Amazon. It removed all the other minor scratches inside and outside of the tank, but not from the magic eraser. What do i do?

I have noticed a white sort of liquid when using these sponges? Is that the actual sponge disintegrating or a cleaning agent added to the sponge? Do your sponges leave that white liquid when using it? I ordered a pack off Amazon, there's not much information on the label as to whether or not anything has been added.

what about use as a filter sponge?

I just can't get past regarding these as safe. Perhaps they are, but I'm hesitant to try them.

Would it be safe to leave the sponge in the filter?

Great video. Are generics fine?

I use Mrs Eraser. It cleans my glass AND cooks dinner.

Will it scratch my tank if i use it to scrub algae

These things do dissolve as they are used. You’re correct in that they’re like sandpaper. But wiping algae off glass is unlikely to break it down. On that note, a regular sponge should work the same. If it doesn’t and these work better, then some of this thing is dissolving as you use it.

Question : would this have any impact putting them into the filter? I have a koi pond at work that will not clear up. I have tried everything

I used to use them until they removed paint from my walls. Lol... I suppose then, they could effectively remove algae.

WAY overstocked tank!!

Can we use this as filter media?

Those chubs are too much for me man. Lol they look like long worm-like piranha. Lol you should throw a ball of frozen blood worms in there and let us watch them go ham.lol. I love your tanks. Thank you for sharing everything that you do Dan. I was checking out a certain cat fish. I am now glad I am not going to get it. I want a fish that I am going to see. I had a bad impulse buy and got a blotched cat. But in all fairness I do not have anyone to clean the bottom in the tank.

I mean whenever I get a new tank and forget to buy an algae scraper I use magic erasers. Not on my saltwater buton that freshwater tank on my channel I used to use magic erasers check out my channel to see it the more subs I get the more tanks I can afford lol.

I"m wondering if anyone has had success removing hard water stains from the inside of a tank with the melamine pads? I received an old tank where the water level was low for awhile. So far, not much has touched it...even vinegar and green Scotchbrite pad before the tank was set up.

Ur dh(dire hardness) is greater than the glass so it wont fall apart on glass....now some rocks will deteriate sponge due to rocks dh

Always use em walmart brand

Is it safe for a reef aquarium?

🤔interesting 😃👍👈

Yes, that melamine is another thing from China that has killed countless of animals. China even put it in some baby food and there were countless deaths because of their greed. Thank you Fishkeeper for all your great advice, this has saved so much time and money, blessings to you!!!

I know the magic eraser ( Mr Clean Magic Eraser) was banned from europe at the time of it's launch because it was considered to be a risk for skin cancer. To still sell it in the US, they had to recimmend users wear gloves. So not sure how save these are all around, have not seen recent evakuations.

Dude get on with the demonstration already

You should use the magic eraser on your thumb : )

Just used it on my 55 gal fresh water to clean glass and build up on filter... all of my cichlids are dead and/ or dying right now. DON’T USE IT!!!

logically, if it works as a sandpaper - it will scuff/haze acrylic tanks. ALSO, if it deteriorates then it's contaminating your water with the non-biodegradable particulate abrasive matter. you think thats safe for our fish? OK Good luck... Poor fish.

It's obvious you don't have a lot of experience with these sponges. The LAST thing I would do is cut them into thinner sponges. They really don't last very long, and they disintegrate into almost nothing. You basically use them until there's not enough left of them to hold on to... which really doesn't take all that long with normal cleaning. I have used them for algae cleanup, with a small piece rubber banded onto a chopstick. It will release a fine particulate into the water, like a cloudy consistency, no chunks. I found it a bit odd for you to recommend something without actually having tried it yourself.
