How deep will 250 DE go

[Harleyguy]

I am thinking of buying a 29" tall tank. I already have some 250 DE MH lights 14K. Will these be ok for a tank this deep?

Thanks

It would work fine in my opinion. You might have to limit what type of sps you can keep down low, but otherwise it should get pretty good penetration that deep. Are you using 14K Phoenix bulbs?

[Harleyguy]

no I'm using 14k aqua connect.

i think your good: but if you wanted more intensity down there, consider a good quality 10k bulb as these are the most intense.

where can I get a good par meter? and what should my par be on the sand?

I am running two 250's DE on my 30" tall tank with a 10" canopy and lighting seems to be pretty good low down.

[Harleyguy]

Have you measured the par down low yet?

[Harleyguy]

The only reason I'm concerned about the light at the sand is my fiance' wants clams.

[phlipper84]

have not measured but I am did have my clams on the sand at one point and still have one down that low.

If you stick to 10K lamps 250 will do OK. If you want 14 or 20K go 400.
