As a first year Intex Easy Set pool owner, I have been watching the Simplifying BBB for very small pools (e.g. Intex) thread very closely. I have sort of come up with a similar plan. I purchased the TF100 test kit and am currently using the 1" trichlor tabs (hth brand) and plan on switching to bleach when the CYA hits 40. It is getting close to 20 now but has not quite made it yet. With the trichlor, I get the expected pH drop and periodically have been adding pH Plus (also hth brand) but have ran out so I am switching to 20 Mule Team Borax.
I was wondering though why dichlor was so heavily recommended over trichlor which seems more readily available.
I am not challenging the recommendation, just trying to understand why one is favored over the other.
