First let me say - I have maintained my pool with both bleach and with Trichlor tabs. Both methods have their +'s and -'s, and I'm now on a hybrid method using a little of both.

My question is this:

Has anyone with experience with Trichlor tablets noticed a difference in the quality between different brands.

In the past I have always used Leslie's Pool branded tablets purchased in store. I always hated the strong chlorine blast that I got when I opened the bucket, so this year I decided to try some wrapped tablets and purchased 50Lbs from In-The-Swim (online/catalog supply store).

The In-The-Swim tablets seem to yield a really low level of chlorine, and I have struggled to keep my levels in check this year.

I feed the tablets with a Rainbow (model 320 I think) online feeder. It doesn't matter if I have 3 tabs in, or 8 tabs, or if the flow rate is low or on max, I can't get my chlorine level to stay where I need it.

Any input related to quality of tablets is appreciated.
