First off, your tank looks great!

Secondly, some corals do well under the low light, but for most corals you are quite underpowered for light.

You should be looking at a T5 system with individual reflectors to cover your tank, keeping in mind you need at least 4 watts per gallon of water in order to house all kinds of corals. with the T5's, if you have the individual reflectors you get 300% watts (from what ive been told) so if you have 100 watts worth of T5 globes, you have about 300 watts due to the reflectors. Or alternatively a Metal Halide is a great light source.

you should be looking at 100 Watts of T5's or above or 300 watts of lighting of whatever combination.

hope that helps you a bit.

thankx josh ,
you think i can do polyps with this light's or i need a total new light system

 

[Jmck]

I dont think you should yet, mainly because they require quite a high light from things I have read. I would suggest getting a good lighting system of at least 300 Watts then you can house anything without a worry.

There are some corals and polyps you could have with those lights. You could look into ones like button polyps, yellow colony polyps, look into some of the LPS corals that like low or moderate lighting. There are corals out there you can keep under those lights but you will have to do alot more research to find em.

Welcome aboard Andrea.
With your lights,you can keep a lot of the soft and LPS corals.BUT,those PC lights are kinda outdated.
I ran these T-5 Aquarium Lighting: Nova Extreme T-5 Fixtures w/Lunar Lights over my old 75.
But I think these Aquarium Lighting for Reef Systems: Current Nova Extreme Pro Saltwater T-5 Fixtures would be a better choice.

Hello and welcome to the site! I agree with everyone else, you will need new lights to keep most other corals.

Hello and welcome to the site...everyone has you covered. :)

I agree with Yote.

You have 4x65w power compact lighting.Good enough for soft and LPS corals.It will better to have LPS corals top half rather then the bottom.Soft corals anywhere.Ideally a new T5 fixture with 6 bulbs and individual reflectors would be better but not necessary for the two types of corals I listed.Remember PC bulbs don't last very long(even if they look okay),every six to eight months they need to be replace.

Polyps is a general term.Everything from zoanthids to cloves are considered polyps.You have enough light for polyps.

Those new Nova's that yote recommended seem like a really good deal. I have a 4 bulb T-5 system but I may upgrade to those if I don't get MH's.
