I believe you wanted to substitute cal hypo tabs for the trichlor tabs in the feeder or floater. THAT CANNOT BE DONE!!!!! Cal hypo tabs cannot be used in a chlorine feeder or floater (except for special vented united specifically designed feeders designed for them and usualy only used on commercial pools). The tabs sold for residential pools are designed for skimmer use, dissolve very fast (in a day or two) and have a lot of binders that leave a lot of goo behind.

This does not exist. There is only 1 form of chlorine used in pools that is slow dissolving enough to use in erosion feeders and floaters and that chemical is trichlor, wich is a chorinated isocyanurate--a chemical made from chlorine and cyanuric acid. When the chlorine is used up the cyanuric acid (stabilizer) stays behind and builds up at a rate of 6 ppm CYA for every 10 ppm FC added by the trichlor.
All forms of unstabilized chlorine (and the other form of stabilized chlorine -- dichlor -- are either fast dissolving (compared to trichlor) or liquid.

If you want to use an unstabilized chlorine and have its addition more automated so you do not have to add chlorine daily then you need to look into either a SWCG (your best bet for a residential pool) or a chemical feed system such as a peristaltic dosing pump for liquid chlorine (not that expensive but you need a storage tank for the chlorine and the units do require regular maintenance to keep the running and the tubing needs to be replaced on a regular basis) or a special vented feed system for cal hypo granules (expensive and hard to find for residential pools).

The peristaltic pumps sound attractive because of the price but I have worked with these feed systems on commercial pools (both with and without ORP control) and they do require almost daily checking and regular maintenance so a SWCG is going to be less maintenance once you get it set up. properly.

NONE of these options are going to have any effect on how often you test or balance your water, btw. You still need to test chlorine and pH daily (or at least every few days) TA weekly, and CH and CYA monthly. (If you use cal hypo or have very hard fill water you might need to be testing CH weekly).
