daharley February 17, 2011 February 17, 2011 Is this good or bad ? What are we looking for when it comes to lighting? And what will these kind of readings support?
Guest thefishman65 February 17, 2011 February 17, 2011 What I have read is 500 at the surface at 100 at the bottom. So this might work for a real shallow tank. If they where cheap maybe, but I doubt they are.
Origami February 17, 2011 February 17, 2011 150 minimum at the bottom if you want SPS down there. I believe that ctenophore's greenhouse is set up to give him around 300-350 at the bottom of his tubs. Very few corals benefit from more than 700 PAR according to something I read today. I don't know if that's true or not, though.
daharley February 17, 2011 Author February 17, 2011 Just starting to gear up to get in to corals are sps the ones that need the most light or??? Bear with me please:)
Origami February 17, 2011 February 17, 2011 Just starting to gear up to get in to corals are sps the ones that need the most light or??? Bear with me please:) In general, yes. There are some deeper water SPS that require less light.
daharley February 17, 2011 Author February 17, 2011 Do you know any good resources as far as lighting? Basically I would have to keep sps above the 12" lvl on the setup at the top of the post barring other requirements I haven't gotten to yet?
daharley February 28, 2011 Author February 28, 2011 Probably a silly question, but if I double up I will have double the figures??
OldReefer February 28, 2011 February 28, 2011 You will not double the numbers, but you will reduce some of the fall-off towards the edges. That means you may get a larger area of 130 PAR at 12", but that is not very impressive. I spent $200 on a 24 LED DIY kit for my frag tank, and I am getting 500 PAR 6" below the surface.
OldReefer February 28, 2011 February 28, 2011 Opps I forgot. That is the number I told my wife.... The DIY fixture was more like $300
