Setting up my 150 gallon tank....question re: RO/DI cleaning
Just started to run a Captive Purity RO/DI. TDS meter reads 172 in and 000 out. That sounds good. Two questions: There is already a brownish colour in my DI chamber (about 1/2 at the bottom). Is this normal? And, how often would you routinely clean out the sediment, carbon, Di and membrane cartridges and is it cleaned with tap water or it's own produced water?
Thx, len
