i just set up a new plant tank, auquasoil, high light , high CO2,
the tank is very small, only about 30L, but kinda tall, about 15 inch. the light is 3X24w, although part of tubes are outside the tank surface. i know the light is very high, thus normally only 2 tubes are on.
the CO2 is on 24 hours per day, i do not know exactaly how much, i guess about 3 bubble per second, as all the snail of tank are out for surface gasping for air there is no fish yet, so i do not mind a little high CO2
the problem is, although the first 2 days plants pearling a lot. But now, none of them do it any more, even ricca. meanwhile, all the plants do look kinda sad, not much growth i can see.
the another problem is, there is a white film with some dirty bubbles on the water surface, as there is not much surface movement, i know it is kinda normal when you cycle tank, but i have never see so much, so thick disgusting film.
i guess some kind of nutrition of tank was used up, thus the plant not growing, maybe O2? as the thick film block the O2 exchange.
or marco?
or i should cut down to 1 tube of light?
do i need to change water more often? as i know aquasoil need a lot water change, but i used it b4, never had problem like this.
normally plants do well in new tanks, even no CO2 and low light, where the problem is?
Many thanks
