SPS in 28g?
 

Anyone running a successfull SPS tank in a similar sized (or smaller) tank? If so I would like to know the specs, and your experiences.

Sumpinfish used to run a very successful SPS smaller tank. You can ask him details.

I keep lots of SPS in my 20g. I think the biggest problem is keeping everything stable, as this is harder to accomplish in a smaller system.

Basically.. I keep millepora, digitata, various acros, and they are all lit under my 150w HQI . I have had great success so far.. everything colours up great and grows wonderfully.

I do weekly water changes of about 2.5g . I top-up every second day, sometimes that changes though.. just depends. I dose calcium and alk. and that's about it. I am fugeless and sumpless.

Heh, you'll all think less of me, but I have had such great success so far with SPS.. and I keep 4 fish in my 20g. Some acros do not thrive though. But most do... it depends on the species I suppose.

Anything I forgot , just let me know... HTH

Is the 150 HQI the only light over the tank? What color temp is it? Where idd you get it?

I am going to drill the 28g and add a 10g or 20g sump to hide equipment and add volume for stability.

What fisihes do you keep in there?

Yep the 150 HQI is the only light over the tank. It is a 20k Ushio bulb which will soon be replaced with a 14k of some sort.

Drilling it is probably a good idea.. my reef is in my bedroom and noise is a big factor for me.. so no sump for me.

And I keep two True Percula clowns, a Yellow Watchman Goby, and a Lawnmower Blenny. :D

Thanks for the info!

I hope to drill it AND keep the noise down because this is going into a shared office....

Yeah, I am sure that won't be too much of a problem. I am an extremely light sleeper.. so that's why. Otherwise.. the sound of trickling water can be quite relaxing at times IMO.

Good luck! Let me know if I can help with anything else.

I think I have slightly more than 20gallons in my Hex..but it isn't more than 30 gal. I have a single 175W MH and 2 9W actinics.

I use a dosing pump to add Kalk. (On a small system it is really easy to overdose Kalk!) I started with two part Ca/Alk supplements, but couldn't keep up.

SPS are thriving.

I'll attempt a photo, but I've had trouble posting photos in the past.

Oh...my avatar is a reasonable shot of that tank...you just can't see the light above it.

What kind of gph are you running in these smaller SPS tanks?

I have a 18 gallon high that I have been running for over a year (converted from a 10 gallon before that). The system has a 5 gallon sump and I use a 250W DE halide for lighting. I have been keeping SPS/clams since it was established and it has been going well. I have to agree though that it definately very hard to keep stable, and sometimes your coral color or growth will reflect this. But who doesn't like a challenge:)
