Algaecide first then shock?

[avpowerstn]

I also have a question. Do I shock 1st, then let rest for a day (simmer down), then add the algaecide (Kem-Tek 60% Concentrated Algaecide) ..?? or Algaecide first then shock.
I thought I was told the shock would kill the algaecide..?

Re: Kem-Tek 60% Algaecide

Algaecide works better as a preventative than a fix. SLAM, then add it when things have simmered down.

Re: Kem-Tek 60% Algaecide

So why not just maintain adequate FC after the SLAM process and forget the algaecide?

There is no reason to use algaecide in that situation. It won't help clear up an algae bloom.

 

[Smykowski]

Since switching to TFPC, I have never used algaecide, and that includes the closing process.

Curious -- Did a Pool store tell you to add the algaecide?

Speaking from experience -- My blonde granddaughter has green tinted hair all summer and fall from the copper in the algaecide. The shampoos that are supposed to remove it don't. I blamed it on chlorine but have researched it and found it is the algaecide. You do not need it if you use the methods in this forum.

 

[JasonLion]

There are several different kinds of algaecide. One foams, one stains hair green, another uncommon kind is alright to use. There isn't any kind that both foams and stains hair.

Thanks Jason I did not know that.

No I believe it was a tech working on my Intellitouch system.

I was doing a little research, I have an EZ-Flow fertigator (fertilizer injector), and I am using MegaGreen (Hydroslated fish, which rocks) but I do believe I am getting "drift" from a group of sprinkler near the pool. MegaGreen is famous for making algae thrive. Looks like a need a "Hanna Instruments Checker HC Handheld Colorimeter, For Phosphorus", and some "Natural Chemistry 05121 Phos Free Pool Cleaner" may have to tweak the sprinkler system a bit also. Thank You all for the input.

If you maintain the appropriate FC level for your CYA level, then chlorine will kill algae faster than it can grow regardless of algae nutrient (phosphate and nitrate) level. There are members on this forum with 3000 ppb, 5000 ppb, and even 20,000 ppb phosphate who prevent algae using chlorine alone.

 

[avpowerstn]

I have been having trouble keeping my FC level where it should be, I was just rinsing my cartridges (500 sq.ft.) with water only, I have a 100 gallon plastic horse trough I bought at Lowe's and just received 4-10lb boxes of cascade I ordered from Wal-Mart. Time to use the advice from TFP and soak my cartridges overnight. I have two sets of filters so may downtime is minimal while one set soaks. 20K ppb kept in check by chlorine only...wow. Thank You for the information. I will tighten my FC game.

IF you are already having problems maintaining your FC level, then it may be too late and there may already be algae growing in the pool. If you Perform the Overnight Chlorine Loss Test you can determine if there is something in the water and then start the SLAM Process.

 

[avpowerstn]

Excellent, I will perform the overnight test.Thank you
