Anemone Lighting

[Reefman29]

I want to put a BTA in a 20 gallon, yes I know it is small. Anyway, would a 150 watt metal halide with 2 actinics for another 28 watts be too much? It has mounting legs or a hanging mount. Any other ideas on lighting are gladly appreciated. I just don't want to spend more than about $200. Thanks for any help.

No, that would work just fine. I don't see any reason to spring for more in this case, unless you plan on keeping even more demanding organisms (which, in a 20g, there shouldn't be many at all). I'm using a 250w on an 18" 25g cube, but only because of seagrasses.

Should I hang mine or use the mounting legs?

Whatever is comfortable/practical/safe in your situation. I would get the lamp as close as possible without running the risk of splashing (cracked glass) and too much heat. The latter shouldn't be as much of an issue with a 150w, though. I know I can get my 250w about 5" from the surface without a problem, but I also keep my temps around 82 degrees or so. I also personally like to hang my fixtures.

If I mounted it right to the tank do you think I would need a heater or a chiller? I live in Pa just for reference.

As already noted, heat shouldn't really be an issue with only 150 watts.

You just need to observe your tank. Every situation is different. If you can hold temperatures down without a chiller during this time of year, you don't need a chiller.

If you can keep temperatures up in the dead of winter, then you probably don't need a heater.

No way to tell without knowing your your tank reacts during certain times of year.

Okay, I wasn't sure because I know that metal halides get hot, but heat does rise so I will probably need a heater. Thanks
