i use a 32g brute container on wheels. I mix 24hrs before the PWC
. I heat and stir the water with a heater and powerhead. I use a syphon and 5 gallon buckets to empty the 20 gallons that i change out. THen I use a powerhead with vynil tubing to pump the new water back into the sump. It takes me about 20-25 mintues.
When i'm not using the brute container, it sits in the garage with the bucket of salt inside of it. I make sure the container is comletely dried out before i store it. I just don't have room for it in the house.
I think i do it fairly similarly to tecwzrd. The thing i've found out is that if i simplify how i do PWC
's, i don't mind doing them. That means that i'll do them more often which is a huge plus.
