Battling Algae - yellow

Postby skos007 » Wed 22 Jul, 2020 14:34

I have a salt pool

I have used a couple of different Algaecide. used Black Algaetrine about 2 months ago and Phosphate Remover about 2 weeks ago. I also added pool stabilizer a week ago.

My water test from pool store came back normal. I have a gunite pool with salt system.

I am brushing with Milliard wire brush.

It seems like it will go away but then come back as in areas I do not see algae but pool is shimmy. Also some area show algae.

What else do I need to be doing?

What is normal?
You really need to Slam (Shock Level and Maintain) with relation to Chlorine / CYA Chart and Recommended Pool Levels
Turn off the SWCG and use plain bleach
Don't use copper algaecide as the effects aren't always desirable. Use a Polyquat 60
(Any brand as long as the ingredients are "Poly [oxyethylene (dimethyliminio) ethylene (dimethyliminio) ethylene dichloride" at 60% concentration.)
You really need to get yourself a decent FAS/DPD test kit (Taylor K2006c or TF Testkits TF100 in the states) to get accurate results as maintaining an appropiate shock level means testing quite often during the day
