Lighting question for 20 gal .

[minaraiko]

Hi everyone.

I have a 20 gallon long with a 20 watt Life Glo 2 bulb. The tanks has a few anubias plants, horn wort, java fern, water wyseria, water sprite, and a melon sword. Should I go with the All-glass twin tube light srtop which will give me 2 watts per gallon or can I get the twin tube Nove Exreme t-5 fixture which will give me about 2.4 watts perr gallon. I am surrently using Flourish and want to avoid co2. Thanks in advance for any replies. =)

Stay away from the T5 if you want to avoid CO2 usage, the Nova Extreme are T5HO and would put you closer to/over 3wpg. For your plants the all-glass should be more than enough.

might and to think about just adding one or two screw in power compact bulbs.

Thank you for your replies. I had a feeling that the t-5s may have been too much for my tank, but wasn't sure. I'm new to plants.
