Chlorinator location

After realizing that chlorine pucks in the skimmer isn't the best idea, I picked up a perform max chlorinator off C/L. Haven't yet installed it and was wondering about location. The chlorinator makers seem to recommend installing between the filter and pool return line. I read somewhere here that some recommended installing between the pump and filter as the chlorinated water keeps the filter from growing nasty things in it when not being used.

What is best? Is the increased water pressure from being upstream of the filter a possible problem?

Plumbing wise, installing it between the pump and filter would be nice as it requires shorter hose runs.

1. Using skimmer tabs is NOT a bad thing . . . unless you have a timer on the pump. In that case, you need to make sure the pump runs 2 - 3x per day, and not just 1x. Problems result when people let tabs sit in their skimmer for 18 hours at time, with no circulation.

2. I don't know that particular chlorinator, but many of them restrict the pool water flow . . . and that's bad. Possible the worst of all is the Hayward inline chlorinator, which has a restriction a quarter -- $0.25 -- won't go through. Watch out for that.

3. Where you put is is not critical, UNLESS you have a heater. If you do, the chlorinator needs to be down stream of the heater, and possibly, needs a check valve between the two.
