Sunlight Supply 4 bulb 54watt enough???

[messina06]

for a 90 gallon tank.

I do plan on having a mixed tank with lps and sps and zoes.

Thanks.

Also have 2x 24' power compact 65watt that I plan on putting actinics in.

Four is OK but I'd feel better using 6 for the sps.

It'll be ok. Placement will be very important however.

I was told that I may be able to run t-5s off my PC 65W ballests. any others hear of this

 

[Phong33]

Exactly what kind of ballast is it? Brand, specs?

 

[messina06]

when i get home i will check and repost the specs.

I run a 6 bulb T5 on my 92 and it is just the right amount of light.

I have the 6bulb on my 90g.

Spend a little more for the 6 and have no worries.

 

[messina06]

Well, I changed my order to the 8 bulb so I should be good to go, although i am now broke

I think it'll be ok for softies and invertibrates but not for hard corals. A clam would be very marginal...

I have a derasa clam under 4 -54w t-5 on a hundred gallon tank and it's doing great.
