After much research on this site, I decided to order the 8 gallon liquidator. It arrived on Thursday, and I installed it on Friday. I was able to use the hole where the unused chlorine puck used to connect on the input side, and I was able to connect to the basket drain on the output side. Got the adapters at the home store. I initially did not install any check valves. Was able to reach full pressure (5). I did notice when the pump shut off the liquidator would drain through the input hose. I wasn't too worried about it, but decided to try out the check valve. This stopped the draining, and had no effect on pressure. Now I just need to play with it to figure out what setting works best.
While I was at the home store, I also picked up a cover for it. I got the Weber grill cover (the kind that goes over the round charcoal grills) and it fits perfect! Cost about 10 bucks, and I use a bungee cord around it to keep it in place.
Question for those with the liquidator: Do you find yourself having to constantly adjust it based on how sunny it is, or have you found a setting that that works no matter what? I know that the amount of bleach I used to add to the pool would vary daily based on how sunny it was. I used to always bring the FC level up to 5 ppm every night. Sometimes it would only drop to 4, and other times it would be down to 2 (with zero CC, so I don't think it was anything other than UV burning up the FC).
Second question: Would running my pump during the day, when the sun is out and burning up the FC be more effective than running it late in the evening or over night? Just wondering if replacing it as it's being burned off is any better than replacing it after it's been burned off.
