High Phosphrate reading tap water 5.0, but want to EI dose.
Currently my tank is in a black out due to BGA. Comes off tomorrow. I bought myself a Phosphrate check and checked the tap water, came in at 5.0.
So if I want to EI dose a 180L tank, how do I do it, if the water in the tap is 5.0. I dont have access to RO water.
Do I have to put something in to absorb the phosphate or just reduce the Phosphate EI dose?
Anyone help me before tomorrow
