Thanks!

[@jessecastro8453]

Good job man, as a retired poolman I have come across this many times. I mainly did commercial pools but also residential, I can't tell you how many times I was flagged down by a desperate home owner who said her poolman stopped servicing the pool, it is green and they are having a pool party in 2 days. Everything this guy did was spot on with the only one exception. I would return the next day to do a complete filter clean cuz if you have algae in the pool shell you also have it in the filter tank and you have to get rid of it. The best part was picking up the check and having the homeowner praise you and thank you.

[@SwimmingPoolAZ-SPS]

On a DE or Cartridge, it would be a given for me to tear down and clean the filter. For this one I ran some sodium-hypo through the filter and did a big (actually several) backwash

[@killerjunior310]

You must of not know what you was doing

[@enmodo]

Jesse if you add that much chlorine how would it be swimmable in two days? I know it burns off but does neutralizing all the algae also use enough of the free chlorine to making it safe to swim again?

[@jessecastro8453]

@Simon Waddington yes Simon. It takes a lot of chlorine to turn a algae green pool around. With algaecide eats up a lot of the chlorine. After filter clean, let pump run 24hrs. Check chlorine level next day, vacuum up the dead algae to waste if you can. Then adjust ph and chlorine level. Should be good to go in 2 days at least. If chlorine level still high. Knock it down with some Thiotrine.

[@Hershewed]

How does go about filling in a pool

[@randymotter51]

Glad you mentioned circulation as a major factor in the results, I once worked at an apartment complex that let its pool pumps get into disrepair and they barely circulated the water in the pools, so getting them clean and stopping the growth of algae was a constant battle and ultimately a losing one given that they barely had enough people to do all the work. No matter how good you are at cleaning these, the owner still has to be on top of maintaining all the important equipment.

[@SwimmingPoolAZ-SPS]

As you know they go hand in hand. It takes like 3-4x the Chems to know out algae on a pool with a bad pump.

[@BackyardBeeKeepingNuevo]

It was nice to see that you admitted your mistake. Not many people will do that. Let alone on KZbin. 👍

cool vid, reminds me of my days of treating pools back in San Antonio TX. we didnt use an algaecide back then , we used chlorine gas and with fresh water we add a stabilizer . i remember i went out to treat a green one and by the time i was done adding chlorine it had turned blue .. pretty cool stuff ... we would also plug the skimmer and run it from the main drain to clear it up after brushing ...

[@magical.melody674]

Wow! I have never seen a pool Go from green to blue in one day! That was amazing!

[@drdrew3]

It only cleared up that fast because all the water was new from a fresh fill and only 2 weeks of missed chemical service. It doesn’t take very much algae to give that bright green color. A few more weeks and it will turn dark green and then black - that takes several days to fix

[@thetoking_6128]

we use pool rx blue algaecide and that stuff works as a charm. havent seem algae since the beginning of spring when we were first adding them to our pools.

[@ezimm81]

I loved how you had to address adding chems to the skimmer. Been a service tech for 20+ yrs and always added chems to skimmer u less it was liquid based chlorine. And still have had heaters on pools for many many years. Not as bad as everyone thinks

[@ddtuss2585]

Adding a liquid isn’t as bad as the people who put the Chlorine tablets in the skimmers. The bleach gets circulated out quickly rather than constantly being in there.

[@drdrew3]

Some chemicals are specifically designed to go into the skimmer but most are best diluted into the main pool - important to know the difference. You don’t see equipment failure immediately but a pool inspector can find early evidence of damage in just a few months of chemical corrosion

[@TomWilson8003]

Great video. Thank you.

[@Elfnetdesigns]

I used to have a pool but I had it filled in. We just stopped using it and the money spent on having it serviced / cleaned to maintain a clear pool was reallocated to other things for the home.

[@kimberlyschwartz5299]

Can u plz explain what u mentioned that it's important to do when u use acid? Thank u

[@SwimmingPoolAZ-SPS]

Always pour over the return while the pool is running and never pour down a skimmer. Acid is denser than water and will sink and damage your pool surface. You can also brush where you poured it to help dilute and spread it.

[@TESFox]

Interesting choice on the poly algicide. My go-to was always silver, though I've been out of the game for a while. Been there done that though, algicide + chlorine + clarifier means murky green to crystal clear in a couple hours. Give it some time to burn off the excess chlorine and good to go :D

[@SwimmingPoolAZ-SPS]

That’s it man. Yeah, the polymer stuff has been working really well for us.

Does acid affect vinyl liners? I'm dreading opening the pool on my own this year. 1st time out of 5 years. Also my water is 1 yr old. Had to replace liner last year.

[@SwimmingPoolAZ-SPS]

Pre dilute your chemicals in a bucket of water and you should be just fine.

[@bioberserkrgaming]

Judging by the video speed settings this likely took about 3 minutes real time. This is based off of him starting to pour at 9:20 and it being completely blue (visually) at about 10:30 and the speed being somewhere between 0.50 and 0.25.

[@Eddysstrangesituationplayers]

I've been taking care of pools for 15 years, 5 on my own now. I do like your method and may try it soon. Using liquid bleach didn't cloud the water like 12 lbs of shock would. Good job!

[@Cavediver86]

He didn't even clear the pool. All he did was shock it. Of course it will turn blue but this pool will take days to get back to clear and sanitary.

[@bobamus1987]

Use a pool vac with cal hypo in it. Power vac with no more than 1-2 lbs at a time, and you’re good. Minimal clouding too. Max dispersion as well.

[@Eagle1538]

Shock or any algasides aren't needed in my opinion. I've been doing pools 13 years in SW FL. Regular chems will take care of any bloom no problem. Cool it changed color so fast. But its gotta filter out still and he spent alot of $$ on that stop! 2 jugs and some acid would have knocked that out overnight..

[@andrewharrison5740]

@@Eagle1538 completely agree. I never use algaecide myself. Just liquid chlorine and time to filter it out with a few backwashes/cleanings in between to help it along. Lowering the pH does help too. People really overestimate what chemicals are necessary for a clean pool. In my own pool I just use liquid chlorine, and muriatic acid when necessary to lower pH. That's it. My pool is so clear, you could throw a quarter into the deep end and still read the date, lol.

[@danielfield5764]

Can I ask why you used an algaecide when Sodium Hypochlorite would have dealt with the algae anyway? Thanks.

[@SwimmingPoolAZ-SPS]

Supplementing with an algaecide can speed up the process as they tend to attack the algae in different ways than the chlorine. Also, Sodium-Hypo dissipates very quickly where the algaecide will stay in the water and work longer. It’s sort of like preparing for a battle with an army. Sure you could just throw ground troops at the enemy but you can also call in an air strike to help the troops get the job done. In short it can be done with just bleach but adding the right algaecide means lugging less bottles and a speedier recovery.

[@balkangetaway]
