Yeah I just found some on ebay for quite cheap. May not last long but I only need to drill 4 holes in relatively thin glass, so I think they may do the trick.

What size hole is generally needed for a 1.5" bulkhead? I thought 2" but does it depend on the bulkhead itself? Or is there a standard?

You should phone up rona to see if they rent the bits. I bought some holesaws from ebay but I never did look for bits.

You guys think this retrofit would be enough light to make my fish look good???:mrgreen:

Would I be better just ordering two? Nice thing with retrofit is I can just add another if its not enough!

Which bulbs would you recommend with it?

Im going with the T5 retro fit. Nicer reflectors and it will cover the tank nicer. I can also add another if its not bright enough.

Oh and another question. I got my closed loop pump from "Nautical" today...Thanks again for delivering man! Its a beast...It will be more than enough flow for my closed loop. Its rated at 6000 gph, so even with a bit of head loss and elbows, it will be a lot for a 115G tank. Now Im thinking that I will go with less flow through my sump and refugium because the return pump does not need to be a factor in providing the tank with flow. What would you say is ideal flow through a sump and refugium without being too little? Im thinking a MAG18 could work but it just seems like so little. Any ideas?

Or maybe the Sequence Snapper?

Have a 145g with a Dart on a CL. Started with a monster pump pump that even with head loss was giving 2000+gph through my 75g sump full open. After running awhile, valved it back to ~1000gph which seemed better (pulling less bubbles through, more settling of detritus, etc).

Ended up replacing the return with an Iwaki 70 series (still get ~1000gph).

Yeah I may valve this thing back a bit. But this is a 6 foot tank and I want good flow across it. Its also going to be barebottom and really for that to work effectively needs lots of flow so no detritus settlings. But it will be set up with an option to valve it back if needed.

Overflow-Have the glass but need to make it black. Anyone ever used Krylon IN their tank for long term and had no bad effects? I don't think I would go this route but apparently its quite the debate around the net...Seems to be about 50/50 boths ways on whether its safe or not. Otherwise, I may just leave it clear and hide it with rockwork a bit and then hope coraline covers it fast.

Return Pump-I have the 2" drain for my overflow and want to keep the flow through my sump and refugium pretty low. What is a ideal flow in a sump/refugium? I have enough flow through my closed loop that the return does not need to be a factor in the tanks flow. I think I will use a mag drive, so a suggestion would be great. There will be just one elbow at the end of the return and the head will be about 5'.
