What do you think, HQI or older Mogul
I have a 150 Watt HQI Pendant hanging over the waterfall I am starting tomorrow night. I started to think , actinic , wattage , etc. Am I going to want corals? Wait - this is a fish only display - or isn't it? So - I have decided that I will try to make it work for both. I found a OLD matal halide system, (2) 250W 10,000K halides with 2 40W Coralife Actinics. Here is my issue. I changed the bulb in the smaller HQI pendant and it looks 10X brighter than the old fixture I have. Out of the 3 tank operation, these tanks are 27 and a hlaf inch square. I am only making 2 of them reef ready. The pendant lights the 2 boxes brilliant. The new bulb I put in is HQI 14K. My question would be, what is better for the corals and life in the tank. The newer 14K pendant or the older full canopy system with screw in bulbs. My friend tells me a 150W HQI is much brighter and more lux than the older style bulbs. The fittings are there and its already hanging. Should I use iut and rely on the 14K to provide all the lighting, or do those 40W old coaralife actinic 40 watters need to be on the coral. Something tells me the HQI is the way to go. I just don't wand insufficient lighting in the actinic spectrum. Any advise before I get the ball rolling tomorrow? Also, that shelf looking coral on the home page, slightly left in the picture, looks like small shelves and grows in plates. Does anyone know the name of that species? Thanks!
