250w is moer baie for a tank of that depth, if you want to keep sps's they will work lekker.The specs of my tank is 900L X 500D X 480H
I have T5's at the moment but want to run MH and T5s. What should the gap be between MH and top of tank? Will the MH be to much for such a size tank?
Thanks Jacques, The skimmer i have is rated for a 1200L tank. So its rated approx 6 times more than my tank volume. Any other advice?Keyaam - just an example:
Puppy (David) has 3 x 400 watt metal halides over his 1.5 metre tank. His tank is (I think) 800mm deep..... ALSO - he has 8 x Geissemann 54watt T5's as well.
So, NO - it is not OVERKILL.
Only thing that you have to watch out for, is your water temperature, with a 250 watt metal halide, it might just sky-rocket.
And: AS Viper has already said as well - you should be able to ANY coral under those lights. You might perhaps just find that LPS might not extend as much, due to the HUGE amount of light.
To keep SPS, you will just HAVE to make sure that you overskim by at least a factor of 2 to 3 times the water volume (meaning, that your skimmer should at least be truly rated for at least 2 or 3 times your total water volume of your tank and sump together)....
Good luck mate!
18 blades:yeahdude:Keyaam - that is a good skimmer (I have/had one) - the only problem I had with it, was that the impeller kept on breaking - the impellers are what Red Sea calls: "turbo impellers".... (with something like 14 blades)....
BUT - you should get good milage out of that skimmer, until you need to upgrade to a ReefTek/ReefOctopus/Deltec or something similar... ;-)
