Hi, I recently set up an experimental tank at 15 July, my last attempt was unsuccessful so I want to find solution and learn. English is not my first language but I will try.
This is a 25cm tall 30L tank, light source is 14W T5, 5 cm above from the tank. I also cover the tank with tower so there are no other light source.
The tank is bare bottom but it has four party plastic cups containing inert gravel and two containing some aqua soil (looks like AS, but not sure which brand) , they are cut into 4cm height and used as the plant pots.
I dose 2x EI daily and use liquid carbon for the carbon source (easy carbon) .
Filter is a 1000L/H canister. Tap water here is realy hard, both GH and KH are above 20 degree.
Plants are staurogyne repens and rotala sp green. No fish.
Repens seems growing well. I accidently up root some of them during water change, I notice that repens in the aqua soil pot have longer and thicker new grown roots than those in gravel pot.
Is that normal? I guess that is because the soil is lighter and less compact than the gravel?
Rotala's growth looks stunted, the new leaves are small and some of them are twisted. Could this be the plant is still adapting?
Tank also apear to have surface scum, not too bad but they are there. From what I have read, surface scum means the plants are not happy with the current nutrient/Co2/etc.
I think there are enough nutrient since I dose 2x EI, I am worry to dose more liquid carbon than the instruction.
Maybe too much light? I can reduce the light by blocking it with paper, that would reduce around 50% of light, but it looks too dark for me.
The tank has only been running five day, so I would leave everything as how they are now, I also did a 50% WC today.
Any thought?
