I washed him with my vacuum cleaner , I handed the maximum discharge, and since the state remains stable.
Today, 18 days after planting, plants have continued their respective previously detected at the 10th days.
Just after planting
3 days after planting
6 days after planting ( algae growth )
10 days after planting (after cleaning )
17 days after planting
tray seems increasingly gloomy about the pictures, because plants that have reached the surface. Without flash, the light begins to fail, but the picture is poor.
photos also highlight another lighting problem: the ends are dark. Indeed, my tank is 120 cm long tube with 90 cm. It therefore lacks 15 cm on each side.
All this convinces me to anticipate the purchase of additional lighting to increase the power and also better coverage ends. T8 at 120 cm is too large, and those at 105 cm too rare, I move into a T5 115 cm and 54 W. I then 114W for a real 180 liters, or 1.6-1W liters.
