Aquarium Advice Addict
Has anyone tested their RO/DI water for PO4? I have had a cyano issue for awhile now and I tested the RO/DI water using a Aquarium Pham. Phosphate test and got a reading of .5.
I have recently read that a cheap GAC filter can leach phosphate into the water. I have one of the popular units off ebay and get a TDS of 0-1 from the 100 gpd 5 stage system(I don't use the 6th stg carbon)
Any thoughts?
