I've bought another test kit which can test NO2 more specifically, and my NO2 came up as 0
I also bought a Ca test kit yesterday, and by Ca is between 540 - 560mg/L (apparrently 1mg/L = 1ppm) I use Seachem Reef Advantage weekly - might have used it too much
I've placed the kenya tree in more direct flow, and I must say, it seems a little bit better.
seapug: that is just the thing, I've not been neglecting the tank, I put in soooo much time and effort weekly, but went wrong about it:
~ I bought the tank on budget, didn't have money for decent lights or sump
~ Couldn't find RO water near, so used tap water with dechlor (never knew it didn't remove the NO3!)
~ Had too little flow
I've fixed all of these except the lights and sump, so the tank is recovering, but I'm still struggling with it
