Hey Burt, the forum has been very quiet today.

Are you mounting just the Metal Halide lights or the T5's as well?

Hi Burt - sorry man that I did not see this thread earlier...

You can use any water-resistant paint, ie. Dulux Velvaglo, or perhaps Marine White (this is paint used to paint areas around harbours, etc, that is tested to be saltwater proof)....

Alternatively, you can use something like a white or very light grey epoxy paint with hardener.... this too will work....

You preferably want the inside of the hood to be either white, or as reflective as possible.

W.r.t the lighting you have - are you just going to have the light lie on top of the tank, as you have in the pic?

You will have to contend with heat generation, as the lighting will cause your tank water to become much warmer...... did you ever think of installing some fans inside the hood as well? Fans that can blow onto the water's surface to improve evaporation, which would assist with the cooling of the water?

waterproofing, installation

Quiet or not,masa is THE FORUM.
think of it as a "drive through" with a notice board.:p

How many times do you expect somebody to drive past to notice something of interest to them?;)


Members are also looking for help, and items of interest to them.
NOT everybody has answers available when we'd like to have them.

..... patience , you'll will get your deserved responses


MAYBE below info will help you?.


Cut out ventilation slots on sides, and or rear.

Install fans to assist in cooling, AND reduced condensation problems.

Cut/Rout spaces for your floodlight fittings, ONTOP of canopy.

try to aim for minimum 150mm distance between water surface and fitting glass cover.

This will allow almost even coverage of tank by both lights, and reduce heat/coral light shock/burn issues.

Waterproofing
Use woodoc 55
Follow directions....
Apply 2 coat minimum.

Install fluorescent T5/T8 in front of and behind floodlight fixtures.
Make an effort to use the BEST reflectors for these lamps
....more light, less waste!!

Ensure all ballasts are away from evap/condesnation/splash damge.

DO NOT install ballasts in cabinetry, they need cool ventilated area for safest, best operational efficiency.

Waterproofing with resistance to UV and moisture... one solution:)....Epoxy.

Heat build up....many solutions....primary solution would be not to close in your lights (dump the lid) Blow the heat away from the surface with some type of fan. PC fans are good to go

I don't know if you will have such big issues with heat, as I have seen those CFL floodlight fittings on a 50 liter tank, fitted about 5 cm from the water, and no heat issues.. One or two pc fans should be more than enough to keep the temp stable...
