Shaz Posted October 19, 2004 Share Posted October 19, 2004 I think I decided to get the 250w MH pendant instead of the 150w for my 29/30 gallon tall nano. I was wondering if I would need a chiller.... Does anyone here have a 30gallon or smaller with a 250w mh pendant, that does NOT have a chiller? here is a link the the specific pendant.. http://hellolights.com/ocli25hqiame.html I have air conditioning in my house for the hot summerdays, but I live in Michigan, so we get a cold winter. During the summer I dont want to just run my house's AC just for the sake of my nano. Thanks in advance P.S. If anyone thinks the 150w would be a better choice instead of the 250w (I want to keep sps, lps, and clams) please let me know before its too late Link to comment
JonPM Posted October 21, 2004 Share Posted October 21, 2004 150 isn't going to be good enough. Before investing in a chiller, I would just try hanging the pendant maybe 8-10" above tank, and have a fan blowing over the top of the water. I think this would be good enough, but then again I've never used MH before. Just trying to save you some $ Link to comment
Samc Posted October 23, 2004 Share Posted October 23, 2004 Why do you say 150 isn't enough? I have a 150 de over my 29/30g and plan on keeping sps and clams. It is PLENTY of light, as far as I can tell. Great spread, penitrates completly to the bottom. And heat hasn't proved to be too much of a factor, with it 6" off the water. Haven't added anything but rock, sand (1") and a stray hermit-all from my 75 g fowlr. But, looking around on the web for a 13k bulb-I have a 20k now, not too much blue but thinking about a little more light-they are hard to come by for de period but more seem to be made in a 250 watt version. I think I might go with a 10k as my next bulb choice, one of the bluer ones. Most people advocate more light the better, but then people have thriving sps tanks under pc's. So, I personally say that either one is fine and 250 is overkill on all but the 29 and above (those people running 250's over 15's and 20L's are crazy-no heat prblms my a#@1). Also, being a nano, we don't need insane growth rates-the coral will overrun our tanks!!! Sam Link to comment
Shaz Posted October 23, 2004 Author Share Posted October 23, 2004 But still the 250 would be better right? And again, Would I need a chiller with a 250w? Link to comment
phergus_25 Posted October 23, 2004 Share Posted October 23, 2004 i would go with a 250 ovwe a 29 i have a 250 over my 20 and it is grea tbut i would go with the 250, you might not have a problem wiht head, so get it and see like the guy said go with a fan blowing if it gets real hot. but you get a lot evaporation. i'm glad i didn't go with the 250 for my so but if i had a 29 i deff would Link to comment
Shaz Posted October 23, 2004 Author Share Posted October 23, 2004 Do you have a chiller on yor 20 gal with 250w MH? Link to comment
phergus_25 Posted October 23, 2004 Share Posted October 23, 2004 o no mine has a 150 DE it stays at 80 or 79 but with a 250 on a 20 i would either have it real high or need a chiller but i think you'd be fine Link to comment
NanoReefTexas Posted October 23, 2004 Share Posted October 23, 2004 I keep my apartment around 68 - 70, I like it cold, and am awaiting hte arrival of a 250 watt retrofit MH for my 10 gallon nano, in which I plan to place LPS, a couple SPS, and definately a crocea clam. How far off the top should I place it? Link to comment
