hi everbody i was wondering if i had enough lighting to grow sps corals in my tank. i have a 125 gallon tank with 3x175 mh 2x96 pc?

What is the depth of your 125g? 60"L x 18"W x 24"D or 72"L x 18"W x 18"D?

717w / 125g = 5.7w/g <<<< Plenty of power to keep SPS under. The depth of the display will determine the height at which the coral should be placed.

ty for the reply the tank is 72" L 18 " W 23" deep.i am also looking to put clams on sand if thats possible with my lighting

I have 3 x 175W MH on my 125 and it supports some SPS. But I find that they do best towards the top of my tank. Some more light demanding SPS will not do well.

Ty frog for your reply yes that what I have been doing with 2 sps that I have is placing them at þhe top and they are doing well but I was wonder about the bottom because I'm thinking about clams

[pogodzib]

I agree with Frogfish as I also used to use 175w halides over my 125 gallon tank and it was enough light for most SPS to survive, but at the lower levels the more light demanding corals struggled some. As for clams, I used to keep a crocea clam on the very bottom in the sand and it did very well.

what about Blue Maxima's clams? would that work on bottom

[pogodzib]

I've had bright blue Crocea clams on the bottom and, IMO, Maxima and Crocea clams have very similar lighting needs. Some other types don't need as much. If you decide to get a maxima clam and if it seems to not be getting enough light, raise it up to the middle of the tank and it should be fine.

thank you.. i also have a pic of a coral that i dont have no idea what it is i bought some star polpys and its on there need help i have pic. its the mat looking stuff on the rightIMG00055 00002.jpg. need help thanks

[pogodzib]

It's tough to tell from the pic, but star polyps have a purplish mat when they are closed up, although it doesn't look very purple from the pic. Other options could be a type of sponge or encrusting montipora. Can you peal the coral up or is it hard? Also, how thick is the coral?

[lukky424]

hi ty for the reply but its hard and you can not peel it..here is some more pics no one seems to no what type of coral this is ?IMG00057.jpg
