reptilez Posted August 17, 2011 Report Share Posted August 17, 2011 Hi, would 2 of these be good for growing corals in a 130L marine tank ?? http://www.trademe.co.nz/Building-renovation/Electrical-lighting/Lights/Inset-lights/auction-398945855.htm or would this be better? http://www.trademe.co.nz/Building-renovation/Electrical-lighting/Lights/Inset-lights/auction-398980290.htm thanks in advance Matthew Quote Link to comment Share on other sites More sharing options...
myfishybuisness Posted August 17, 2011 Report Share Posted August 17, 2011 i think they 70w would be better because it would give a better spread and be just as strong at the ends of the tank, but the 150w would be just as good imo , so each to there own Quote Link to comment Share on other sites More sharing options...

Zayne Posted August 18, 2011 Report Share Posted August 18, 2011 i mean if you need bulbs for marine get new ones Quote Link to comment Share on other sites More sharing options...
the-obstacle Posted August 18, 2011 Report Share Posted August 18, 2011 You'll be wanting 10000K - 14000K bulbs for marine so you're best bet is to replace the ones that come with the fittings. They're not expensive through fish-street.com. Quote Link to comment Share on other sites More sharing options...

Zev Posted August 18, 2011 Report Share Posted August 18, 2011 Actually, the 150w would be better in my opinion, the DE lamp the fitting takes is the same as a lot of the marine lamps that are available on the market that have the correct colour temperature. The downlights appear to take single ended lamps, and you may struggle to get the correct lamps for marine. I have 150w MH over a 108l tank, and it grows softies well.

Ok so i will get the 150w Metal Halide if you think it is better...so do you use DE 10000k bulbs?? Quote Link to comment Share on other sites More sharing options...
Zev Posted August 18, 2011 Report Share Posted August 18, 2011 I think I have a 14000k lamp in there at the moment, the colour is a bit yellower than I would like, but different brands behave differently. The best one I had came from Wonderworld in Rotorua, and Ardie took it out of a new fitting to sell it to me because he did not have any in stock. I will see if I can dig it up and see what brand and temp it was. Quote Link to comment Share on other sites More sharing options...

Zev Posted August 18, 2011 Report Share Posted August 18, 2011 Nahhh... the lamp is past it's prime and I would not even give it away! Just because it still glows rather brightly does not mean it is putting out the correct light, the coraline algae would not even grow it was so old!
