After doing things the wrong way for a couple of years like dumping huge amounts of powdered shock in the pool in the spring after leaving it uncovered in the winter and trying all sorts of "magic bullet" elixirs like " Yellow Rid" as well as constantly using chlorine pucks I have finally gotten my pool in hand using BBB and my SWCG. It took draining and refilling a major amount of water in the pool and probably a lot more bleach than it should have because of my lack of a proper test kit but I got it done. Then I set about fine tuning the balance of the water with borax and baking soda and also powdered stabilizer in a sock hung by the return. Up until a few days ago, the only "pool store" product I was using anymore was the stabilizer. The only problem I had was that even though my water tested well and no matter how many times I rinsed the cartridge to my "skim filter" my water still had a very very slight cloudiness to it. It just wasn't the sparkling clear I remembered from the first summer I had the pool. The filter wasn't even getting very dirty either. That first summer I had the pool, I had cloudiness once after an extended period of heavy rains. Back then I used Clarifier and the pool cleared back to sparkling seemingly overnight. So the other day while in Wally World, I stopped by the pool aisle and could not resist buying a bottle. I put the recommended dosage in my pool and while the results were not as dramatic as I had remembered before, there has been a definite difference made in the water in the last couple of days. If it's not quite sparking, it's close. I've also noticed the filter cartridge has been much much dirtier the past couple of times I've cleaned it with nothing, no swimmers etc., to account for extra dirt. It seems as if the clarifier is doing what it is deisgned to do which is make the tiny particles that get through the filter clump up so they don't anymore. So I'm kind of wondering what the school of thought is on clarifier with BBB. I know the general consensus seems to be to stay away from pool store chemicals and I agree after what I've been learning here but I can't argue with the results of the clarifier.
