Hello everyone,
I had set up a planted 40 gal tank about 4 months back with Caribsea Ecocomplete. Its cycled (ammonia, nitrite 0, nitrates 10 ppm) and is fully stocked (102% AqAdvisor). While the fishes have been fine from the beginning, for the last 2 months, all my plants have gradually stunted and were showing extremely poor growth. I have regularly dosed ferts (NilocG ThriveC, 2x dose per week), liquid carbon (glut), have medium lighting (Beamswork DA FSPEC 36"), do not have much of an algae problem and change about 30% water weekly. My plants include easier to grow species like water wisteria, Bacopa monneri, dwarf sag, rotala indica, etc which I have successfully grown before in my previous 29 gallon tank on Seachem fluorite/regular gravel mix.
So I got frustrated last week and decided to check what was going on. The pH in my tank is freaking 8.6 (tap water 24 h resting pH is 7.6), GH is 6, kH is 3. I googled around a bit and saw many complaints about EcoComplete raising pH which seems to be batch dependent. So after researching a bit, I have decided to move on to UNS controsoil which apparently lowers these parameters and releases much lower ammonia than something like ADA amazonia.
So here is my question:
1) Would adding a 1" layer of UNS ControSoil on top of EcoComplete would bring the effective pH down? Of course, I will cycle the soil separately before adding to the tank.
2) OR should I completely replace the EcoComplete with some generic inert gravel from Petco and then top it off with 1" Controsoil (which is quite expensive).
Thank you.
