水草情迷

my 電磁伐 and Meter is not working at all,
and it is too expensive to replace a new one ......

can i keep my co2 on for 24 hours???


lighting time is 8 hours now,
shall i light more?????

since there is lot of "cho" before,
so i keep the lighting time at 8 hours,
but now is okay to extend longer lighting hours .....

sorry, there is no chinese input in my company computer ....
