I use 3" tri-chlor pucks when I need to drive my CYA levels up. I have a Pentair Rinbow 320C inline chlorinator. I used to use it when I had a single speed pump and in general I was happy with it.
However on a slow speed filtering there is not enough water flow to sustain the levels of chlorination needed. I did several modifications to adapt for lower water flow:
- switched to top level feeding
- removed the regulating switch (WOT all the time)
- replaced the feeder tube with large diameter one
Still there is not enough flow. I'm wondering if anyone has any suggestions to make it work? if not with this chlorinator is there any kind of a gizmo that would work for my situation? Obviously I can put the pucks into the skimmer but I want to avoid this for obvious reasons.
