Lots of guys are saying- I have Alga in my pool. All I read is- do the slam. If you use Algaecide 60 With chlorine level on target, you should not get alga. Just asking.
Ok, I understand that. I see lots of guys getting algae and doing the slam does cost money. A bottle of Algaecide 60 Plus is $17 and putting in 4 oz every week is a great prevention. I use 4 oz a week with my pool that’s 86,000 or more. $17 bucks last all season. Your going to need Algaecide 60 Anyway for closing?If you have your chlorine level on target, you don't get algae. Why do you need an extra expense in that case?
Also algaecide is a preventative. Adding it to a green pool will do approximately nothing. Adding it to a clear pool will help prevent algae if the FC drops too low. But not allowing FC to drop too low prevents algae better and keeps the pool safe to swim in, so again, why bother with the extra expense?

Marty:
Algaecide is only used during pool closings and in very rare situations. I honestly believe you have a situation where you pool is quite large, and there is limited circulation. To avoid getting algae, you will only need to keep your CYA/FC ratio in check, but the weekly brushing (at least 2X weekly is necessary). Are you brushing your walls frequently?
This year I have not brushed yet. Last year when pool service was doing pool. Yes, I brushed a lot because I was seeing green alg were it went from 4 ft to 9 ft. I now use a submarine and put 3 tabs in it. It sits at 9 ft deep. Circulation was the problem at 9 ft. I now leave the bottom 2 drains open. When it’s winds and leaves are falling I close bottom drain to get max suction at skimmer. I do put in 4 oz of algae 60 in every week. So far Pool is spot on. Im still lowing the CYA. I’m at 250 now. When I took over the pool it was off the chart. 350 to 400. That’s because the pool service guy was putting in 3 tabs in each skimmer (3). As I learned more about pools I fired him. Also pool guy said to leave bottom drain close all the time, you don’t need ???Marty:

This brings up a question regarding the life span of polyquat and how FC affects it. Chlorine seems to oxidize a lot of things, is there a chance of the polyquat being broken down by higher FC levels?
I haven't used polyquat since finding TFP. The 1 quart bottle I bought is still sitting on the shelf barely used. I keep away the green with free chlorine.

No I stoped using tabs and bought cal hypo and liquid chlorine 10 % since my tap water is very soft and pool water is at CH 30 using cal hypo should raise it. I also bought 100 lb CH raise but only use 30 lb. I’m still dumping water out and refilling.You're fighting high CYA and yet you are still using the tabs?
