Hi all, I want to start dosing E.I in my tanks but i also want to have soft water. I have an R.O unit that i have been using for well over three months and my Rams are loving the soft water. I have no nitrates or Ammonia, my PH is around 6.4 - 6.7 and my GH and KH are 0. I add some electro right to put my GH to about 5 and my KH is about 5/6. My question is if i use EI dosing (I have KNO3 KH2P04, MgSo4,K2S04 and ther trace mix..all from Aquaessentials) do i have to make allowances for the fact that i'm using R.O water and is therfore stripped of everything?? I have an 18 Litre Nano tank and a Rio 180. I use CO2 on both tanks (well Excell on the 18 litre, preasurised on the nano) and i have about 4wpg on both tanks. I think what i really need is someone to tell me use 10ml of this and 12ml of that. I'm not the best with Maths and i think i'm getting confused!!! I have made my own solutions up using the directions from the aquaessentials website and am happy to throw them away to start again!! Sorry to be a pain! You probably get a lot of stupid peolpe like me!!!
