1.即係唔夠光 ? hmm.. 即係可能要加多枝燈,一係換過枝 ? Yes, at least you should have 24Wx4. BTW, I'm curious... are you sure that the height of your tank is 18"? 'cos it doesn't look like so. You can't even hold your water inlet tube and CO2 glass tube vertically...
2.即係8個鐘光 + 8個鐘co2 ? This is a quick way to do. Or, some pros would suggest to turn on CO2 30 mins after the light is on, and turn off CO2 30 mins before the light is off. BTW, try to lower the CO2 diffuser closer to the bottom of the tank. You may consider to use UP's simplified mini diffuser. That would allow better CO2 diffusion by keeping the CO2 inside your tank longer.
3.唔夠co2. 好,加大d. OK
4.我有枝外置紫外光燈係出水位. 長開.不過d人話長開唔好 ? I turn it on 24hrs a day. Some pros say that the UV will adversely affect the absorption of some fertilizers, such as Iron, and that you have to put more than regular dosage.
5.遲d加風扇. 但係加左燈咪仲熱 ? That's the trade off. You'd better keep an eye on the temp changes. Some pros say 24-26c is the ideal range for plants. I don't use chillers (too expensive for me) and just try to keep it below 28 by using fans. So far, my plants are ok.
6. 開缸時兩日1/3水. 而家keep 住一星期兩次1/3水. 謝謝指教. OK
Also, 8 hours of lighting may be too much for your new tank. Be careful of algae burst. We usually advise to start with 4 hours and increase 1 hour every week until 8 hours a day.
