Can you use glass strips? Ive seen tanks run narrow strips to support the lights.. I have a glass top made for mine too, but got tired of cleaning the glass every 2nd day. And now with the 20g ATO set up, no worries with evaporation

wow i see you have been heavily accumulating your corals, almost looks fully stocked and it hasnt been that long since you got your lighting.

yeah .. the bottom left... see that anemonie ... damn thing was only the size of a toonie.... now look at it... it loves the light.... ur blue frag is now starting to grow onto the putty ... and everything else is NUTS ... cant wait to put more in ... LOL

^^wow it looks purdy :mrgreen:

but certainly not full!! more like 70% empty I say put 40 more colonies in there just use acrylic rods to mount them like trinkets on a xmas tree......

Twon if you have a decent hvac unit in your house then you're laughing cause you can feel like winter even in the summer.

just use the 400 for now and pick up a 250w also hamilton ballast can usually fire most bulbs a ballast is a ballast just make sure if the ballast is a pulse or rapid start and match the bulbs up. Alternatively buy a dual 250w ballast like a pfo, ice cap, or galaxy or really whichever you want so that when you get rid of your 400w you will only need a pendant and bulb.

as for the glass tops just leave them on unless you want to risk your jawfish jumping.... just mount the pendants inside your canopy by hanging them then cut a hole in the back and install 4 pc fans to suck the air out and the heating issues should be gone!

off to the craft store for acrylic rods and staples for more Glue... getting ready for more colonies and frags :D

industrial plastics on minoru acrylic rods 8ft piece for 4 dolla!

wow... ok ill head there tomorrow on my lunch :D gonna glue all the corals and frags... tired of my mexico turbo snails knocking them over

yes i would prefer a 400 over a 250 also but how about two 250 over a 400? if kept in close proximity like only 2-5 inches apart between pendants and having both the lighting overlap i am hoping that it would atleast be close or = to the 400 in par and intensity. i would have more flexability with two 250. i would not have a huge reflector sitting on my canopy and with two hqi i can get small pendants or just the shell to fit it into my canopy just need to find a way to rid the glass top to let the heat escape.

what do you guys think?

with 2 250s... .you will get alot more lighting out of it ... and there is a central over lap ... so the center is alittle bit brighter then the outsides... but now you will also have lights on the sides where you dont have much light now..... as for the glass top ... i think we can rig something up

my 400 reaches all corners of my tank, im not worried about that. my prblem is how it comes out.
