mr_miagi32 yeah the kegs go great and im not too sure about the buts but i will do some research on the net tonight, cant do harm yet as there are no fish
cheers CFC i would have taken pics as i built the hood but i have to borrow the camera from dad but
i basically built a box the size of the tank (out of MDF) with a floor mid way (supported by strips of timber from the top) with spaces for the fluros to slot in then i brought angle steel which was going in the corners See pic where the floor of the light hood rests on and is bolted to the sides the angle steen is bolted to the wall but that was my fault because i didnt but enough to go to the floor and i also wanted it suspended. however i put thos 2 aluminium poles at the front as it was saging with the weight of the lights.
if the fish jump out you could build a wall of perspex into the wood capping but i will see if it happens, cant put a lid as the light needs to penitrate as far as possible.
ps a mangrove setup would be perfect i realy wanted to do it but i want rainbow fish in this tank so ill have to find other options.
