metal halide or t5 ho actinic?

Gabriel.I · 12/09/2009, 12:24 PM

have a aquarium with 90g and i want to keep soft coral,polips,zhoantus...

but i have a litlle problem:distance between water surface and place where I could suspend the lamp is 20cm.practically between water surface and the lamp would be a max 10cm. though I want to bring 3x150w metal halide+2 actinic t5 ho 39w.or just bring t5 ho 6x39w actinic?

I wish I would be better advised to make taking into account the short distance between water surface and the lamp.

thank you

please need some answers for this question.

and I would like to know from people using the lamps above the tank resting on those feet of plastic to tell me what distance from surface water have to lamp.

Actinics would be enough if your tank isn't too deep but wont provide the shimmer of MH.

aquarium has a column of water 24 inches (60cm).

Should be fine.

I would go with half 10k half Actinic.

so it would get 6x39w T5 the 10k for 90g

6t5's, it would be too close for halides.

i dont understand?

t5's all the way, you would be too close for MH's. not to mention the bulb configurations for color, growth, etc. I don't have the thread link handy but check out the t5 thread. I run 6 39w t5's on my 65 with great results. If you have a hood you could retro and possibly get 7 or 8 bulbs depending on what you wanted. I'm in the process to finish my retro and add 1 more bulb for a total of 7. good luck
