Hello all, Quick question for you. I have pretty dang low water pressure. I have a 125 gal tank that I do weekly water changes of 30 - 40 % on. It takes a fair amount of time to refill with my python. About 20 -30 mins to refill tank. This may be a silly question but I am not well versed on water conditioners. Should I add the total amount of conditioner at once at the beginning or maybe spread it out through the refill process? I wasn't sure if the extra conditioner just hangs out waiting for unconditioned water or if it degrades relatively quickly. I hope this makes sense. Thanks!
