Amazing! I'm so glad we could help. That's exactly what we love to hear!

The powder shock. Do you add it right into the skimmer or directly into the pool ?

It worked! Yay!

Just make sure your CYA and chlorine is always on point

That's what we love to hear!

Is the product actually called "no more problems"?

Yikes! Glad you recovered quickly

Glad it helped!

Wow! That's so good to hear. I'm so glad we could help out!

Did you have to keep vacuuming the dead algae off the bottom? If so any advice would help please I have a small 600 gallon 8 foot pool with filter. Can’t get the algae sucked up off the bottom it’s sooooooo small it goes through any filter, pool skimmer etc and if you barely just move it clouds up and then you have to wait several hours or a day for it to settle again.

How often did you vacuum and what did you have the filter set on when vacuuming?

Glad it was helpful!

You got this!

Honestly, shock can solve quite a few problems

Most people don't do the proper steps before using phosphate removers (balancing, cleaning, shocking, etc). And they tend to be sold pretty aggressively. Some pool owners find lots of success using them. But they need to do the other steps first!

Glad it was helpful!

You've got this!

Oh glad you saw this first! Algaecide probably wouldn't have done the trick (and it's so much more expensive)

Glad it helped

Wonderful! Glad it worked!

You're so welcome!

Backwash after the shocking and filter stage

Hopefully this helps you solve this yourself! We hear that frustration a lot

If they're on the cheaper side, I could see how that can happen. I'm not sure it's preventable in that case.

Microbiologist here, I'd recommend using Borax as a relatively cheap and safe way to prevent mold growth. Borax will raise the pH of the water to a level that the mold will not want to grow in. I'm not sure the size of the tubes, but I would try to get some Borax solution (about 1 cup of Borax per gallon of water) into the tubes and mix that around in there for a good 20 minutes. Then drain to hopefully clean and get the rest of the mold out of the tubes. Then go ahead a sprinkle a little dry Borax in the tubes prior to storage to prevent mold growth. When the tubes are needed again, make up the same Borax solution used for cleaning and use that to fill the tubes instead of just water. This should keep the mold under control and really minimize the growth during the off season. I will note that Borax is very basic and corrosive. It's not going to hurt plastic surfaces, but I'd recommend some kind of eye protection and a mask to keep the powders out of your throat and lungs. Lastly, bleach will certainly work instead of Borax but will be much more damaging to the tubes and carries more of a risk when handling. If you aren't comfortable using Borax or would prefer a safer alternative. Use a liquid dish soap solution to clean the tubes and when the tubes are filled to hold down the winter cover. Use baking soda to sprinkle in the tubes for storage when not in use. This likely won't be as effective as Borax, but carries minimal health risk when handling and will likely be a cheaper route.

That's great it worked! Is it a bromine pool or a saltwater pool? And how bad was the algae? The non-chlorine shock could have revitalized your normal sanitizer enough that it handled the problem. All types of shock help remove bromamines/chloramines and increase the active sanitizer available in the water. So while the non-chlorine shock didn't kill the algae, your "refreshed" sanitizer had more power and room to do the work.

@@SwimUniversity I use the Pool Elegance line- basically a peroxide line. What I did wrong was not balancing the chemicals and treating the little bit of algae when I closed it- so when I opened it, it was really green. I added more algaecide, scrubbed and vacuumed as well as shocked it each time I scrubbed it. I also cleaned my fingers after every time I vacuumed. It was a lot of work , but worth every minute . Now I know to fix the algae problem before I close.

Yes it should work! Just watch your dosage of shock since it's a smaller pool

If it's freshly filled water, it might be copper or iron causing green water. Make sure you use a metal sequestrant and tackle that first.

We have a post all about the best robotic pool cleaners and we update it regularly! www.swimuniversity.com/robotic-pool-cleaners/

That's the secret!

You need to flush that filter regularly. Even more so if the pool is green or you’re just circulating the same algae. Also don’t underestimate the power of brushing. Imagine not brushing your teeth but just trying to keep good oral hygiene with mouthwash. Same principle. You have to brush at least once per week and more if you have algae. Brush it just before dusk and then hit it hard at dark with the liquid chlorine. Run the filter 24 hours and hit it again with the chlorine. And clean your filter! Don’t give up. You’ll figure it out. Once you know the routine only laziness will defeat you! Not dissing you. We all get lazy. I’m battling a major algae bloom right now because I was lazy right after we got a lot of rain and hot weather. Now I’m paying the price!

Filter mode

Totally right!

I’m kind of just learning on the fly as for the past 2 weeks I thought I had an issue with pollen until I stumbled on algae bloom today in pools and realized that’s what I’ve been dealing with, not pollen. I’ve vacuumed 5-7 hours every few days and by the time I finish the beginning part has a thin film again on the floor. I’m sorry shocking straight I’ll I’m isn’t working but doesn’t he recommend getting the ph balanced first? Then scrubbing to get the algae in the water, then shocking? Don’t get me wrong I’m not following those steps here, I didn’t even know there was such a thing as liquid shock until last Friday so the week before I was upset my local Walmart didn’t have any bags of shock. I ended up buying an entire pool opening/closing box kit for $30 because it had a green bags of shock in it. Luckily it also has some chemical to control algae so I shocked my pool 3.5 hours ago and just dropped the algae powder in an hour and a half ago, and trying to stay awake here to shock one more time around midnight or 12:30 to shock again before bed. I dialed my filter for the first time and it was so disgustingly gross but I was able to get it like 90-95% clean and add new filter powder successfully and watched the pressure return to a normal range for the first time in over a week before adding chemicals so I’m happy about that. Good luck Lou!

Liquid chlorine added at night is the best shocker. I’ve always had better luck clearing up a green pool with the liquid as opposed to the powder packs of shocker. The powder shock is easier and mire convenient, but not as effective in a badly algae ridden pool.

@@pooky1959 Thnx! I'm about to leave town for a week so I'll give liquid chlorine a try when I get back.

You don't need phosphate remover if you kill the algae with chlorine

Would like to know, too!

@@LaneyaWiles ME THREE

It should be on filter to remove the dead algae

1 dose of shock is for 10,000 gallons. So depending on how many gallons your pool holds, you need a "double dose"

You need to clean or change out your filter after shocking.

What kind of sand filter do you have? I'm wondering if there's a cracked lateral or something causing sand blow back in the return jets. And I haven't personally used the synthetic media filter balls. But if you're concerned, you can try vacuuming to waste or drain so the water is leaving the pool. Then try shocking and running the filter when there's less algae in the water.

@@SwimUniversity Thnx for the reply. I have an Intex sand filter (75 lbs of sand) combined with a 2100 GHP pump. When I discarded the old sand I disassembled and cleaned all the filter parts. All the laterals are in good shape. It does not appear that sand is getting out of the filter. It is just when actively pushing the vacuum head around on the dirty bottom that the filter output turns dark. Stop vac, filter out clears. BTW - your recent green pool video was spot on. After a 3x shock and then a 2x shock the next day I am now at the milky pale blue phase of the clean up. I'll vacuum to waste after the chlorine returns down to normal levels.

Run in on filter

You're so welcome!

Filter

Yes, wait on the stabilizer (you're probably shocking with cal-hypo shock, which is unstabilized on purpose). Without a waste port, you may just need to clean your filter more than once. Have a clean replacement cartridge on hand.

How big is your pool or filter? We usually say manually vacuum after adding flocculant

@@SwimUniversity I have a 5000 gallon above ground pool. I'm trying all of this, but I can literally see the green/yellow algae shooting back into my pool while it's on Filter....?

Yes! Just be sure to avoid cal-hypo shock (that calcium can build up on your salt cell).

Follow the process all the way through with the shock (at least 8 hours or overnight). If it's cloudy blue, run your filter 24/7 (you may need to clean or backwash it before or after). That might do the trick, otherwise add clarifier. You don't need to vacuum clarifier.

You definitely need the filter for this, so it sounds like you'll need to wait

This was so amazingly helpful thank you! I did shock and got rid of the green without the filter. After floc, I then siphoned to garden. The once the weather was better, I set up the filter and now on a mission to get it crystal clear, hopefully nearly there!

You might have an air leak or a clog in the skimmer line. Check your connections and O-Rings first.

No it just changes the alkalinity level in your pool.

Oh no! It needs to be back within normal-ish range (around 3 PPM) before swimming

That will lower your alkalinity! There's actually no "alkalinity decrease" product

Muriatic acid

No cons, just the cost of running it! Be sure to clean it though if you've had an algae issue.

Could you let us know which video? It should be on circulate overnight, unless you're using flocculant (then it should NOT pass through your filter)

I just switched test strips and this says 3ppm total chlorine and 0 free chlorine.
