View Full Version : Lighting recommendations for a new 70g tank

Looking for some lighting recommendations for a new 70g Deep Sea Aquatics tank. Dimensions are 36x18x25. Right now I am looking at the Aquatic Life R7S HID 36" fixture. It has 2x150w mh and 4 T5's. Anyone use the Aquatic Life fixtures or have some other recommendations?

LEDs. Once you see them, you will never go back!

Unfortunately, LEDs are out of my budget right now.j

I paid about $275 a piece for my LEDS.

Unless you can recommend something around $900. That's the price of the Aquatic Life fixture.

I'll have an Evolution LED 125watt 20k soon. Just waiting for the corals in my tank to sell off. I will be asking $240, its about a year old. PM me if you are interested. It worked great on my 75gal.

1 light on a 48" tank the normal spread is 24" x 24"

I have a 36" Metal Halide fixture with hanging kit. 2x250 watts with moonlights. I used the fixture for about 7 months. If I were keeping the tank, I would put them back up and take my LEDs down. I would sell it to you for $200, I paid about $600 less than a year ago.

Aren't those 250's going to transfer a lot of heat into the tank?

metal halides in general are going to put heat into the tank. in my opinion 150w halides probably wont give enough PAR at the sand for corals and clams since the tank is 25 inches tall. I have a tank similar sized that I am currently building and plan on putting 2 175 SE 20k bulbs, and 2 39w t5 actinic bulbs. I am pretty sure I wont have enough PAR at the sand, but I am only using that light set up as a temp solution until I can build my LED fixture.

Any halide transfers quite a bit of heat. 2x250w is negligible though. Those 150s wont give you a very good PAR rating, although they might with the additional t5. Still $200 is a good deal for that light. I would jump on it,and thats without even knowing what type of fixture it is.

Any pics of the fixture?

Here they are over the tank.

Heat was never really an issue. You would be able to keep whatever type of corals you want. The fixture is a Current USA Sunpod light.

That is a damn good deal. When can I take a look at it? I usually work until 4.
