I have this 15 gallon which used to be a high-tech tank, CO2, fert regime,... the works.
This was converted to a low-tech sometime ago, which E. tenellus, a few crypto sps., java ferns, mosses. Probably because the plants are easy & low maintainence, they seems to be doing fairly well, however I do not get the kind of growth I used to in the past.
I kinda worried since there is no base fert. or soil in the subsrate, and I stop dosing liquid fert. (PPMD, NO3, PO4, K2SO4) for some time now, are fish food as fertilzer sufficient for the plants? I do not feed heavily. Is it okay if I start dosing liquid fert. again?
The fauna are: 10 eyespots rasboras, 6 chocolate gouramis, 3 Ap. Bits and a few malayan shrimps. |
