A cheaper alternative to Grocery Store Baking Soda....

[TheGoose]

I bought it in a real big bag one time from Wal Mart-in the pool section to boot. I think it was about 20 lbs IIRC.

How big is your pool that you use over 50# of baking soda in one year? If you said Borax or washing soda maybe, but baking soda? Why?

A large pool run exclusively on trichlor might need that much.

I run Tri Chlor in my 18x36 IG, and I use at least 25lbs a year. My pool is in direct sun and I lose a lot of water to evaporation, 2-5" a week. My fill water is very low in alkalinity. I also carry it on my truck...

Wow that is a lot of water loss. Do you use a solar cover when not in the pool?

[aylad]

I have basically the same climate as msumoose, and my evaporation loss is very similar. The problem with solar covers in our climate is that, even without a cover at all, by late July the water temps are approximately bathtub warmth, and by August it's usually actually too hot to be comfortable swimming. I welcome the evaporation loss in my pool because it allows me to top off with tap water, which lowers the water temp of the pool enough to make swimming still fun.

Makes sense if that is an issue where you are located. Actually you get more cooling from the evaporation than from adding the tap water!
