Need advice on an R/O system??
I have a 75 gallon planted tank established over 1 year. I am always fighting diatoms. I have very hard tap water. TDS 450+, KH 14, GH 23 and high silicates, PH 8.6. I inject co2. Plants always struggle because of diatoms. Fish are all healthy.
Can anyone recommend an R/O system? I've been researching BRS and Spectrapure and now feel even more confused. I need a portable system I can attach to my garden hose. Di or no DI?. Will a system without DI filter silicates? How many stages?
Thanks for any help!
