    green algae cannot be erradicated

    The only thing rain is going to do is make you wet. Unless you get a monsoon, rain has very little effect on pool chemistry. Does your test kit contain a FAS/DPD (drop count, no color matching) chlorine test? Can’t properly perform the SLAM without it.

    green algae cannot be erradicated

    Following the procedure, lower pH to 7.2 and raise CYA to 30ppm in preparation for the SLAM. Before you do anything, do you have a proper test kit to complete a SLAM? How do you test?

    Constant battle with algea

    CYA is a bit of a challenge at first, I hope this info helps. Pool School - CYA I find it easier to fill the view tube to the first mark, then glance, not stare. If I see the dot, I fill to the next level and glance for the dot. I continue until I don’t see the dot at a glance. If I stare, my...

    Constant battle with algea

    +1 Brushing your pool is like brushing your teeth, it is a preventive measure that should be done regularly. Would you please list a complete set of test results including: FC CC pH TA CH CYA Also, are you doing the CYA test outdoors on a bright sunny day, back to the sun, reading the vial in...

    Constant battle with algea

    Welcome to the forum! What is your CC level? Once the pool is completely free of algae, we will help you keep it that way. I had your same filter and pump on my 6700 gallon pool and found it’s overall performance marginal. It took forever to vacuum, and required backwashes during vacuuming...

    Pool Year of Algae

    Circulation can be supplemented with proper brushing, but as already mentioned, circulation is not the issue right now. You need to focus on FC and pH right now, and we are going to need proper test results to get you back to a TFP.

    Pool Year of Algae

    Those test strips are useless. I doubt a pool with a steady diet of Trichlor only has 50ppm of CYA. If those test results can be trusted, you have two major issues, zero FC and a very low pH & TA. 6.4 is most likely the bottom of the pH test, and the actual could be much lower. If you have a...

    Pool Year of Algae

    As you already know, exclusive use of tablets will push your CYA upward, requiring you to raise FC to keep the pool sanitary. Did you purchase a recommended FAS/DPD test kit last year? What is your daily FC target, and current CYA? Use of chlorine tabs/pucks

    Ladder full of algae

    Absolutely not normal. I’m on my fourth season and have never experienced that with my ladder. I also suspect algae in the main body of water. Are you following the TFC closing procedure for your pool?

    Use of PoolRx

    Oh my..... fire that joker. We use our pool every day during the summer, never a speck of algae. Pool Rx is a waste of your money. Maintaining the proper FC level is key to a sanitary pool. Before I switched to a SWG I would add chlorine daily to maintain the proper residual sanitizer (FC).

    Algae issue with good numbers

    OP has a SWG pool, with CYA of 70ppm, FC recommended minimum is 3ppm, with a daily FC target of 5ppm. The algae is not ‘coming back’, it’s just never been completely eliminated. That will change after a proper SLAM.

    Need Help Getting Rid of Algae

    You must follow the SLAM procedure to eliminate the algae. Regular daily FC levels will not do that. Please take the time to read through the procedure. Also, it would be very helpful to read through the .

    Green Pool this morning, Hot and Humid Party tomorrow... HELP!

    Algae is just a nuisance, it’s only a green plant. But if FC got low enough for algae to grow, it’s possible that bacteria could have as well. Odds are not really, but it’s possible if the FC goes to 0. How long has the pool been consistently at SLAM levels? Yes, visibility is a big concern.

    Green Pool this morning, Hot and Humid Party tomorrow... HELP!

    We are in the same boat neighbor, family cookout/pool party/movie night plans ruined by the weather (I have a projector and 10 foot screen that I hang on the house by the patio). That deep end is far from clear. Yea, I can see the vac, but I still wouldn’t let my kid swim in there...

    Green Pool this morning, Hot and Humid Party tomorrow... HELP!

    Just to clarify, filters to not eliminate live algae, chlorine does. The DE is to help the sand filter catch the dead algae that’s been killed by the chlorine.

    nitrates

    Using Trichlor tabs, you will add 6ppm of CYA for every 10ppm of FC added. Let’s say your pool uses 3.3ppm of FC daily, in 3 days you will have added 10ppm of FC, and 6ppm of CYA, in 6 more days it’s 12ppm CYA. In 12 more days it’s almost 25ppm of CYA. Before the end of the month you’ll be...

    Dead algae not filtering out through sand filter

    Algae spores are microscopic. By the time you see green, there are millions of them. The floc you added should be vacuumed to waste, your ‘pool guy’ should have told you this. It is not good to put the floc into your filter. It will make a mess of the sand. Have you looked at any of the info...

    Dead algae not filtering out through sand filter

    We do not normally recommend using floc, it usually creates more issues than it corrects. Floc will need to be vacuumed to waste, does your filter have that option? Vacuuming floc into your sandfilter will eventually gum up the sand requiring you to change it. A sand filter is more than...

    Dead algae not filtering out through sand filter

    Hello Gabrielle. Does your filter have the ability to pump to waste? If so you could manually vacuum to waste to remove the algae (and some water) from the pool. Watch your water level doesn't go below the skimmer. If you have been continuously vacuuming dead algae it is very possible that...

    Can my Chlorine pool have Pink Algae?

    Can my Chlorine pool have Pink Algae?

    You have a Taylor K-2006, correct? Why are you going to the pool store? If you see someone here post a CYA over 90ppm, we always recommend an extended (diluted) test. A CYA result of 121ppm is impossible with the Taylor CYA test, even with dilution.

    Can my Chlorine pool have Pink Algae?

    Agreed, the SLAM procedure mentions nothing about adjusting TA. Did you lower your pH to 7.2?

    Can my Chlorine pool have Pink Algae?

    If your CYA is 100, your absolute minimum FC is 8ppm. Telling me your FC is at 3-4ppm is meaningless without a good CYA level. Regardless of how it got started, if it is still there, your sanitizer levels are not high enough to kill it. As it reproduces it will overcome the FC much quicker.

    Can my Chlorine pool have Pink Algae?

    Welcome to the forum! Pink slime is a bacteria, which means the sanitizer is too low to kill bacteria. Algae is just a nuisance, it’s only a green plant. What you have is a bacteria growth and it needs to be handled properly.

    INTEX - 2,000 Gallon SUMMER SLAM!!!!!!!!!!

    If you really want to finish this quickly, check and dose more often whenever you can. If this were my pool, and I saw a loss of 18.5ppm in 3 hours, I would start checking/dosing every 30-60 min until I could get FC to hold better. Of course life gets in the way, but the point is to try to...

    INTEX - 2,000 Gallon SUMMER SLAM!!!!!!!!!!

    If your CYA is 80ppm, you should be SLAMming with a FC of 31ppm, not 8-15ppm. [FC/CYA][/FC/CYA] If the pool is only 2000 gallons it may be more cost effective to drain it all and start over. If you insist on SLAMming, I would drain half to get the CYA down to 40ppm.
