20g Long Frag Tank Lighting

[Frag Freaks]

I am going to be setting up a 20g Long as a frag tank. It is going to be a closed loop setup which I am going to be pushing 1050gph through.

I plan on having 4 x 24w T5 bulbs to be used for lighting with an IceCap 660 overdriving the bulbs giving me approx 156 watts total.

Will I be limited to only softies and LPS in this take or will I be able to house SPS also.

I think you can take on SPS due to a 20g long is only 12 inch deep. IMOHO, that is a lot of flow for a 20 gallon tank.

I think you'll definitely be fine with overdriven bulbs. Might even be too much considering 20g longs are pretty short.

I was going to have valves to be able to adjust the flow. I would rather have too much and turn down the flow as needed rather than not enough. At full blast I would be looking at roughly a 52 times turnover rate.

What would you suggest as a turnover rate for SPS?

The flow and the lights should be fine for most sps. As long as you don't directly blast the corals with the returns. I had about 60x turnover in my 20l mixed reef.

52X and that lighting plan sound just about right to me

We run around 1800gph flow in our 20 long sps frag tank, between the return and a mp10 set on 100% reef crest, but before that we had 2 evo750's which kept the sps happy. For lighting we use an Apollo reef led fixture, but before that we had a 250 watt hqi.

So I ended up with a Sunpod Fixture to hang over the frag tank. It is only their 70 watt model. I got a good buy on it from a fellow club member.

The question is now, since its a downgrade in the lighting department of what I originally planned. I am probably guessing that I will won't be able to keep any SPS and if so maybe very limited.

With this lighting and the same flow of 1050gph what will I be able to house for corals. The fixture right now is about 8 inches or so from the surface of the water.

Here it is cycling. I am going to use this tank as my main tank for awhile until I can set up a 120g that i have planned for the future. After that that the 20 will turn strictly into a frag tank.
