Pink algae

New here and am looking for any reason for pink algae. I have a 22,500 inground pool and use Baquacil instead of chlorine, more expensive I know, but enjoy the positives from it. In the past two or three weeks, I have developed pink algae. Treated it yesterday with extra strength algicide and two pounds of non chlorine shock. I keep brushing it daily. What might be causing the growth of this pink algae? Thanks in advance

Welcome to TFP :)

The reason for it is Baquacil does not kill Algae... Chlorine kills algae.. Algicide does not kill Algae, it is used to try and prevent an outbreak..

I am very sorry you are you having issues with your pool.. When you want to have a trouble free pool we will all be very happy to help you change over to chlorine... There are many who have done it and have never looked back and have beautiful pools now that are safe to use..

IF you plan to stay with Baquacil, to get rid of the white mold you'll need several gallons of Oxidizer, Line Cleaner if you can find it and the non-chlorine powder shock. You will need to tear down and clean your filter. Most likely a sand filter? You'll need to pull off the multi-port and clean it as the mold will hide everywhere. You'll probably need to replace the sand. The internals in the filter buried in the sand will need cleaned. If you have a big pool light in a housing (niche) you will need to pull it out and clean it. There isn't one thing that Baquacil has created to get rid of the white mold and their costs are skyrocketing.

I had a baquacil pool from 2006 until May 12, 2021(the day I was finally converted). I have only a 13,700 gallon pool and have been battling the white mold gunk since 2018 -every year about this time the pool would begin to cloud, gunk began to appear in the pump basket and every time the slide was turned on, stuff would start flowing out. It would get so cloudy you couldn't see a few feet down, nothing would clear it and pool store was no help. I dumped so much baquacil chemicals in the water would taste and feel bad. With Sanitizer jumping $5 to $49 for 1.5 qt bottle this year I just couldn't take it. I probably spent $1,500-$2,000 the last couple summers, each, to swim for 4 months. In 2018, I found this community looking for guidance. They suggested then to convert.

Unfortunately, I never found a Baquacil community like these great people here. Since converting to a TFP pool, swapping to a DE filter, Salt Water Generator and also wiring in a timer, my over all costs and time have dwindled. While not a fan of the chlorine smell, I have gotten used to it. I constantly get comments of how clear the water is, how great the water feels. I test daily or at least every couple days. With the SWG, my test numbers have stabilized so that I feel I could leave it for a few weeks and it would be the same when I returned. PH is the only thing that has fluctuated which is simple to maintain as well. Since June 1st, I have only added 1 qt of Liquid Chlorine and a little acid to bring down pH.

I’ve never even heard of pink algae. I’ve seen pink biofilm before though. I must google now. Best of luck to you though. I know nothing about your type of pool sanitizing unfortunately.

Thanks Matt. Yep every year about this time, white water mold or algae of some kind. I might consider switching over next spring. I see your from Bluffton. I'm up here in Archbold. Enjoy the rest of your summer.

Nice village, been there many times. The Barn still a favorite restaurant, was there a few weeks ago after seeing the new 'town' at the Village to the North.

Here was my step by step, almost day to day conversion: May the fun begin - conversion of 15 yr Baquacil pool
Its long but very documented on the process. I know there may have also been some CDX in the water still but I can say, I am much happier and have less stress walking out on the deck, wondering if I would be able to see the bottom or not. The attached pictures were from 2017 when it started to get bad. All chemical levels were almost perfect but who wants to swim in this? 1st pic is the pink/white mold on the first step, 5 inches of water and still cloudy. 2nd pic is of my robot, hiding at the bottom of 7ft of cloudy water. Took 3 more seasons to give up on baquacil.

If you decide to switch next spring, you'll want to find a good source for liquid chlorine 12% (sometimes 12.5%). It can be from any of the residential water treatment companies that service softener systems. Now is the time to read up and educate. ABC's of Pool Water Chemistry - Trouble Free Pool and a must for conversion is TFTestkits.net TF-100 Test Kit with the XL option for testing FAS/DPD CHLORINE & CC'S.

I was in your position last summer, hesitant to switch especially since it was like learning a who new language or at least a different dialect!

I’ll start by echoing the cheer to switch to chlorine. That said, I’d say you’d be crazy to switch this late in the season. You’re looking at about a two week process to convert and may only have four or five weeks left in the swim season…….depending on weather/equipment pad. So let’s try to pinpoint why you’ve got yucky water.

Can you post a full set of results like your sanitizer and oxidizer levels?

next spring would be a GREAT time to convert over after the winter rain and snow :)
