please can anyone recommend an alternative to liquidKH/GH tests as being red/green color blind they mean
little to me - the TDS meter I added to my RO unit is top because it gives me a number instead of me
standing there like a numpty trying to decide if its orange or green/ green or orange
have been reading the fora on chemistry and I need to inc my nitrates as its currently 0.
I use dennerle V30, E15 and S7 - can I add daily KNO3 to this brew? I have a 275litre planted tank (100x50cms wide x 70 cms deep) with co2, 4 x T5s 10hrs per day and some slow growth going on. I have very few fish (4 x elderly cardinals, 5 x peru neon green corys, 1x sae & about 12amano shrimp). I plan to add about 30 harlequins this weekend - will this raise my nitrates enough or should I still add KNO3 to my fert regime
thanks
