looking for light recomendations for a 20 tall tank

[pascal32]

I have two 20 gallon frag tanks that will be up and running shortly. I was hoping to put MH on one and T5 on the other.

what wattage MH should I be looking for 70 or 150?

for the T5's is 4 bulbs too much?

thanks!

I believe the 20H dimensions are 24x12x16? I would suggest a 4x24w Tek; it would work great. I believe Dan just bought one for his 20H, maybe he can chime in. If you can find one used (they are no longer sold), some people also like the Current 150w Sunpods. Hope this helps!

I have a 20h and I use 4 t5s and I have kept almost everything in there without a problem.

If you're trying to grow everything including light loving SPS, go for the 150 or even 175. I had a 175 over a 20 for about a year and everything grew well.

I do 4x24 t5 bulbs on my 20H with great results.

I was leaning towards the 150MH and a 4 bulb T5. Time to find some used goodies!
