Hi all, looking for some advice on the best kind of dosing for my tank. I have a 240l, CO2 injection (in line diffusion). I have been dosing with TNC Complete, usually 20ml after a water change (twice weekly), occasionally supplemented with root tabs in clay substrate. Lights are fairly low (the Fluval LED strip that came with the tank) on for approx 9 hours a day. Fish stock is 9 black ruby barbs, 6 boesmani rainbows, 4 mollies, 7 sterbai cories, 3 sodalis cories, 2 apistogramma, one clown pleco and 3 nerite snails. Typically do two pwc per week, totalling 50% water change weekly. Have been running this set up since Christmas.
I would consider the tank to be moderately planted, growth has been good and I'm largely really happy with my modest achievement. However, lately I've noticed some plants (especially hygrophila polysperma) shedding a lot of leaves (five to seven a day), often with holes which I believe indicates a potassium deficiency. My nitrates are always around 20ppm due to our tap water, so I have been considering swapping to EI dosing, skipping on the nitrates and focussing on the other macro / micro nutrients. Is this suitable for my kind of set up or would I be better sticking with liquid ferts and just upping the dose?
Any advice greatly appreciated!
