Hey all, I am currently cycling my tank and whilst I was testing the tank water for ammonia I figured I'd test my tap water for Nitrate and Phosphate. Nitrate is almost zero (maybe 1) but Phosphate is 2.5 possibly slightly more.
I was planning to dose TNC Complete once the tank is setup but now I'm thinking that's going to be no good because of the already existing Phosphates in the tap water. Can someone confirm this is the case?
I will be doing 50% weekly water changes to reset everything but as the tap water has Phosphates in already it will be resetting the Phosphate levels back towards 2.5-ish once I do the weekly water change.
If the TNC complete is no good I presume I will be best making up my own EI mix? Any advice on what I would need to mix taking into consideration the existing Phosphate?
