Hi Pool peeps. I can't find one thread that covers it all to ask the questions so here I go.
How does one deal with mustard algae attempting to grow behind a submerged pool light beyond brushing it out every 5 days? I don't use algacide now. I maintain FC of 7-10 (which seems to keep the below algae issues from going nuts, when I go lower I struggle more), TA at or about 100-120 (see below for more info on this), CYA is presently at 80, pH is 7.4-7.5.
In the creases of my ladder I also get what appears to be some sort of mustard algae attempting to grow. Yes I brush weekly using a mask and snorkle to get close and inspect my entire pool.
I have fill water that is high in alkalinity. What is the pros and cons of constantly fighting the chase of the number 80 because I can't get to 100, let alone 80. By the time I get to 100, I need to top off my pool again. And no, I have no other water source available from which to fill my pool. The higher alkalinity...is this why my salt cell gets that blue-white build up??
Lastly, if my FC is usually around 7-10, should I bump my CYA to 90??
Side note, I had considered borates but have given up on the idea due to a lower TA being unattainable. Any suggestions on the above issues would be greatly appreciated. My water is crystal clear and I've not let anything cloud it up. I'm a bit anal retentive about keeping it very clean given the past algae issues and on going struggles with the light and ladder.
