SRC Member minireef Posted August 11, 2006 SRC Member Share Posted August 11, 2006 Intend to keep a bit of SPS(30%) at the top of the reef, is my 2x150 MH OK? if not what is the minmum? I do have a chiller and tunze wave maker. Thanks in advance Quote My Reefing Mission:- To manage the waters and lights with efficient resources, disciplined husbandry and prograsive knowledge.

SRC Member madmac Posted August 11, 2006 SRC Member Share Posted August 11, 2006 If you make your water really clean, it is possible.... BUT, having 2*250W MH will make it much easier for you. Quote Link to comment Share on other sites More sharing options...
Moderators thomas_lim Posted August 13, 2006 Moderators Share Posted August 13, 2006 I have personally seen someone using 150W for his SPS tank and his SPS grow as well. Some of his SPS is even in mid water. His setup also uses a tunze wavemaker. Like what Bro MadMac say, clarity of the water is the key to this.

Wht's the height or rather depth of the tank that u hv seen using 150W? Quote Link to comment Share on other sites More sharing options...
jamomatt Posted August 14, 2006 Share Posted August 14, 2006 I personally using 2x150W MH + 2x54W HO T5 Growth and health is not a problem, only colours I can't tell how it will turn out as I have not kept them long enough for any conclusion.

jervismun Posted August 16, 2006 Share Posted August 16, 2006 Hi bro I previously used 2 x 150W for my 3ft, it looks very bright to me. So shouldn't have any problem with SPS being on top of the reef. However, having 2 MH spread across 4ft length may be a bit more tricky as you may end up having darker zones. Secondly, what chiller are you using? Is it underpower? If yes, then consider properly before overloading your heat emission... then you will have upgrade your chiller... double whammy Quote Tank 60x40x40 Optiwhite Glass Tank Sump Elos 500 w/ Tunze Overflow Protein Skimmer Skimz Kone SK1 Return Pump Hydor Seltz L30 Wavemaker Hydor K1 Illumination 150W + 2 T5 Chiller Arctica 1/5hp w/ Aquabee 1000 Water Top-up Tunze Osmolator Dosing Pumps Grotech 3-Channels Calcium Reactor Deltec PF 501 Computer Aquatronica Link to comment Share on other sites More sharing options...

SRC Member Dorado Posted August 18, 2006 SRC Member Share Posted August 18, 2006 I start with 2nos of 150w mh with 2nos of t5 for my previous 4x2x2 sps tank it started fine but after 2 mnth most of my sps turn dull and start to brown out. The intensity of 150w is not sufficient if you go for full sps unless you focus on locating directly under it. Futher to that the illumination will not give you a wide and fluent spread to cover the whole tank. I reckon that the best solution if you gonna to stick with 150w, add- in more T5 as 2 nos really insufficient to keep the sps healthy and maintaining the colour not forgeting good growth rate. I know a reefer using just t5(8 tubes) for his sps tank. For me, In using 3x 250w with 2 t5 actinic for my 4'x2.5'x2' currently. Quote Link to comment Share on other sites More sharing options...
damienkee Posted August 25, 2006 Share Posted August 25, 2006 IMO, no problem at all. but some might not showing their true colors only...... Quote Link to comment Share on other sites More sharing options...
jervismun Posted August 25, 2006 Share Posted August 25, 2006 IMO, no problem at all. but some might not showing their true colors only...... Then that's a major problem... what's the purpose of keeping SPS and not be able to see their true colours?

Moderators thomas_lim Posted September 22, 2006 Moderators Share Posted September 22, 2006 Wht's the height or rather depth of the tank that u hv seen using 150W? Sorry, I didn't check this thread earlier. The person tank is a 2LX2BX1.5H using just 1 150W-10K Giesemann Nova II lightset. Light is placed abt 8inch off the surface. The SPS are placed in mid water level. Light do play a part in browning out but the biggest culprit is the nutrient level. Suggest you try Monti first. They are more easy in tank with a bit of nutrient. IMO, i think they prefer tank with some nutrient. Quote Tom Link to comment Share on other sites More sharing options...
