I have been using tabs to try and increase the CYA a bit. Does not seem to be working. CYA is stable even though I have been feeding tabs and supplementing with bleach to keep up with the load from swimming and sun.
I was particularly nervous about tapping the return for the pump since, if I screwed it up, it was going to be a major re-plumb as there was no room to cut and couple. Fortunately the tap went well and the fitting does not leak.
Now to dial in the feed times.
I am considering just doing a run with the stenner wide open in late evening to replace daytime loss.
What schedule do you all run your feed pump on?
How much should I run the pump after the feed?
