Continuing to Lose Chlorine after Switching from Baquacil

[Lynne0616]

Thank you for your quick response! Yes, it has been drained several times in the past 20 years of using Baquacil. It was even drained 3' (leaving 1' of water) this year.

So, we will be replacing the filter sand tomorrow. Hopefully, that is the problem. It is too late in the season to drain the pool, so if need be, I will keep shocking it at night until I only lose 1ppm. What should I do during the day since even with the floating Trichlor, the FC goes down to zero?

Is my TA of 190 ok? My pH dropped down to 7.2 from 7.4...so am aerating again. It likes to stay at 7.0.

Next year, I would like to go with a SWC system. Any suggestions of brands? Also...do you have a favorite heater?

Thanks for your help.

190 in a vinyl pool isn't really a problem, especially since your CH is low. If it was 400 or 500 you might have a problem.

I'm in my first year of an SWCG so see my comments on my results in the SWCG forum here. It won't save you money but it may save you effort.
However, I think you should clear up your remaining Bac problems first, so your FC doesn't keep dropping.

I have a FantaSea pool, first cousin to a Kayak.
