Can; The original pendant came with an internal ballast and one MH bulb.
I bought another lamp, bulb fittings and wires. The two ballast became external, leaving enough room in the pendant for two bulbs. I made a new larger reflector from polished aluminium sheet.
I rewired the whole setup, so only the lamps are in the pendant, everything else is out, in a (air-cooled) box.
I will make a photo soon to explain better.
TCU Reefer; I experienced an increase in color since I use these trace-elements. Especially the green and blue colors become more intense.
I tested it by not dosing anymore for a few weeks, colors became less vibrant.
Maybe because I skim wet and always use GAC, trace-elements are taken out of the sytem fast.
ycnibrc; Thanks! I experience the same thing with these elements.
iantoh; Thank you for the compliment
Davidb6; I don't feed the corals directly. I feed the fish (and the whole system) by giving lots of different food. Spectrum Thera a + pellets, Prime Reef Flake food, OSI spirulina Flake food, frozen mysis, frozen artemia, cyclopeeze etc.
I feed multiple times a day in small amounts. I believe when you feed the fish, you feed the whole system indirectly. (sponges, tunicates, corals, featherdusters etc.) They break down the food even more etc etc.
143gadgets; Thank you! Of course I have some links
