I used this technique for small black algae spots in my pool. Worked like a charm! For the spots in the deep end, I just jumped in and swam to the bottom and rubbed the chlorine tablet on the spots.
Great idea (on the deep end). Thanks for commenting.

Unbelievable, it works great! First, I was out there with a wire brush, then it was a wire brush and muratic acid, then I pulled out my pressure washer, all of these did not touch the algae worth a shot on my pebble tech. I came in and found your video, went to the store to buy tablets (I have a salt water pool) and started rubbing the tablet over the water line. By the end of my doing the first rub, the algae is mostly gone from the first section. This is a great idea! You have a new subscriber. Thank You!
I'm so glad you found it helpful. Thanks for watching and commenting and subscribing. 👍
Thanks for the tip. Noticed some dark green spots in my pool. I don’t know if it’s black algae. I heard that’s bad stuff for your pool. Gonna give this a try.
Let me know how it goes.
You, sir, are a genius! I tried that on my Pebble-tec pool and it removed all black marks from the water line in less than 2hrs.
Little off-topic, but what do you recommend for removing the stubborn waterline scale from the pool?
That's fantastic to hear!
Regarding hardwater scale on your tile line, the good old fashioned pumice stone. Slowly but surely and don't go too hard so you don't damage the tiles surface.
Pool School Sounds like a project for the next weekend. Really appreciate the advice. I’ll definitely give it a shot. Thanks!
@@None-gv5fs I usually tell my clients to just do a little bit each time they're in the pool that way it doesn't become a daunting long drawn out project. In Arizona our water is notoriously hard and the scale on the water line is constantly there. It's a bummer.
Try this....instead of pouring pool acid directly into the pool try spraying it mixed with some water with a bug sprayer onto the waterline. Works great
I’ll listen to ANYONE in an AZ Cardinals hat. Fitzgerald is the TRUTH!
Side note got black algae at my water line, trying to get rid of.
Oh wow. I'm gonna give this a go
Also thinking switching to Bacquil - Used in Texas had decent results keeping ph etc in check- Instead of hot summers burning off Chlorine soo quick- Thanks again Your thgts
Unfortunately I have no experience with Baquil so I wouldn't be able to comment on it.
Awesome, I was too lazy to drive to the pool store. I did it with a chlorine puck for the toilet
Very inventive. Way to go.
Did it have the same results?
Regarding the pool brush after a few hours what brush do you recommend? A regular brush or a wire brush?
A regular combo brush (which is nylon and metal bristiles, unless you have a vinyl, fiberglass or painted pool then it has to be just nylon. All metal is too harsh for any
The test tube with testers inside do they work better than a Taylor kit ?? What’s your opinion
I'm not a fan of any type of liquid test kit. I use the Aquachek Pro test strips.
I have a bad brown "toilet bowl" ring in my fiberglass pool. I thought it was from all the hackberry tree crud falling into the pool. The brown appears that is runs down the sides of the pool toward the bottom too. I wonder if this will help my problem? I did not have this problem last year.
Hmm sounds like some staining. I had an above ground pool that had a similar issue. It may be algae but it may be something else. You ca try the phosphate remover and some light brushing and see if that helps (be careful with the TriChlor on a fiberglass pool as it could damage the fiberglass. With our above ground pool it turned out to be staining (from what I don't know) but I drained it halfway and used some mild liquid bleach and lightly scrubbed it and it did the trick and then refilled the pool immediately after to rinse.
How long do you leave the pool equipment off before turning it back on?
Thank you
Maybe a couple of hours.
What about diving down to get at marks down on the walls? Thanks.
For that you may want to try using a tablet and scrub it against the black algae. The key is getting the trichlor to settle onto the algae.
Thank you!!!!

Is this ok to do with a vinyl pool liner?
No it wouldn't. That'd be too harsh on it. You may want to try putting some bleach and water (maybe 4 parts water to one part bleach) in a spray bottle and spraying it on the water line / algae line. Leave it on for maybe 20 minutes and wash off.
@@PoolSchooler use a magic eraser, the ones without dawn /or soap... works wonders
@@jeff8700 Thats a good suggestion. I'll give that a try.
Is PR 10k safe for vinyl liners? Thanks
@@jeff8700 I used to the magic eraser and I didn’t take it off my vinyl liner.🙁
I have above ground 30ft oval Holds approx 22 thousand gallons . Have not opened 2 seasons with Covid and lack of pool chemicals . Could not get water crystal clear as before when closed 2 yrs ago. Been same water for oh - 11 yrs or so- I read somewhere recommend drain off half ? What do you recommend ? Have a major challenge now Looks like a swamp and Frogs are at home! 😆😆😆😆 HELP! Thanks
Hmm, if it's been that long I'd suggest treating it like a new pool. Drain and refill it (make sure your clean the filter) then add your start up chems and make sure you keep the filter clean.
Thank you great 411. Question have a 30,000 gallon pool salt and have a bad case of black algae we have shock treatment for 3 days and it helps and we brush brush brush however it’s not my pool it’s a apartment and it’s in the Philippines 🇵🇭
My question now that we have done our best but it’s a 22 x 38 x 5 pool and there is still a little here and there and some here black and you know they grow roots and well is it unsafe to swim in a pool with black algae and there are kids swimming as well, is it really unhealthy to swim with black algae. Thank you,
As far as I know as long as the black algae is minimal it should be safe to swim in. But I would continue fighting it to read the pool of it completely. How do you spent some time in Manila in the Philippines and it’s very very humid and there’s a lot of vegetation around. So that creates a combination that allows for algae spores and phosphates to thrive. I would really recommend getting a really good phosphate remover and using it to rid the water of phosphates. I would follow the instructions that come with the phosphate remover get. Especially with a safety precautions regarding when it’s safe to swim after adding the phosphate remover. You might also have to clean your filter medium more often because of the amount of phosphates and vegetation.
Great video, thanks, do you have a video on how to remove algae or brown spots on a above ground liner pool? The water is clear just can't get rid of the spots, someone told me it's from leaves that sat at the bottom of my pool.
Thanks
They're correct. We had that same issue with our above ground pool when we had ours. You can use the trichlor granules like you would for black algae on the bottom BUT DON'T LEAVE IT ON TOO LONG SO AS TO RICK DAMAGING THE LINER. MAYBE TRY 20-30 MINUTES.
How do you get rid of black algae on the walls of a pebble tech pool? There's none on the bottom or on the water line. I have scrubbed and treated with different types of algaecide to no avail.
First watch my video on treating black algae in your pool. Here's a link: th-cam.com/video/58rEOjmObL8/w-d-xo.html
If its on the sides you can put the trichlor granules in a nylon sock and dangle it against the side of the pool in contact with the algae and it'll do the trick. But you need to scrub the algae with a brush first to "break the skin" of it so the trichlor granules will work better.
I live in southeast Missouri and continue to have issues with what I think is mustard algae. I've used the product you've suggested in one of your videos to remove the phosphates. I've used algaecides,and shock weekly. I use a floatron. I've vacuumed to waste on several occasions and within a hr I get this sandy looking stuff settle in the lower areas of my above ground pool. I've had the water tested at the pool supply company and it checks out fine. Any suggestions??
Jeffrey Stelling if you have the standard filter and pump that those pools usually come with I’d bet that is the problem.
@@PoolSchooler I think it's about a 20ft round above ground. It was here when we bought the house. It had a sand filter with I believe was a 0.5 hp pump. We replaced with a new sand filter with a 1.0 hp pump. We did have this issue with the old system as well,but just dealt with it. We've lived here 2 yrs now and just tired of dealing with it. I mean the water is crystal clear and then you look down and see the ugly settlings at the bottom just annoying
What is your email? I'd like to email you more about it.
Thanks in advance

BTW - I always post it at the end of all my videos as well. 👍
@@jeffreystelling3395 Hmmmm Sounds like your sand filter has a crack or something in the manifold which is allowing some sand to squeak through. REMEMBER, if you don't have a stay in the pool vacuum you will get some dirt and debris settling on the bottom of your pool. So that could possible be that as well BUT one reason I wouldn't think it's that is because the sand is ending up in the same place.
I have had three above ground pools in the last 18 years (they're only good for about 3-4 years in the AZ heat) and one had a sand filter that was horrible and unreliable. The other two I used a larger single cartridge cartridge filter (specifically for above ground pools) the same one on both (yes it lasted that long and it was fantastic!). If you are so inclined I'd suggest changing over to a good after market above ground pool cartridge filter like this one by Pentair which has it's own pump and motor: www.amazon.com/Pentair-PNCC0150OF2160-Aboveground-Cartridge-Filter/dp/B008HYKGIW/ref=asc_df_B008HYKGIW/?tag=hyprod-20&linkCode=df0&hvadid=198100862572&hvpos=1o4&hvnetw=g&hvrand=227479651980899661&hvpone=&hvptwo=&hvqmt=&hvdev=c&hvdvcmdl=&hvlocint=&hvlocphy=9030055&hvtargid=pla-386521583485&psc=1
or the Hayward XStream which is the one I had (albeit it an older model):www.amazon.com/Hayward-Cartridge-Efficient-Filtering-Square-Feet/dp/B00SBQFFPA/ref=asc_df_B00SBQFFPA/?tag=hyprod-20&linkCode=df0&hvadid=241972133686&hvpos=1o2&hvnetw=g&hvrand=227479651980899661&hvpone=&hvptwo=&hvqmt=&hvdev=c&hvdvcmdl=&hvlocint=&hvlocphy=9030055&hvtargid=pla-571213127498&psc=1
I know they're a bit more expensive but they are really good.
An easier way is Put liquid chlorine in a pump sprayer spray it and walk away just make sure you rinse out your sprayer and spray clean water through it because the chlorine will eat the O-rings in the sprayer
I use a light acid for pools and apply it with an old dish soap bottle where I can squirt it on. Then I go right behind it with a stiff brush and it comes off real easy. Best to do it after vacuuming your pool where the water is low and you have to add water afterwards. The only problem is it can throw your PH off.
Thats a great idea. Thanks for sharing.
I use Bromine about 20 years, and the past 2 years we've had an algae problem. We've had a lot of rain and I can't get ahead of the game. Any suggestions
SPORTSHOTS09 Check your phosphate levels it might be that you just have high phosphates in your pool. Also, I get using bromine because it’s less harsh, but I have heard that chlorine is more affective.
