250w Mh

Bought the above MH 250W for a bargain. Need a bulb. Screw in type. Any advice?

 

Hi

Is it single ended or double ended?
10000k, 14000k or 20000k?

 

Screw in type, 14000k

 

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?

 

Just waiting for answers from the gurus!!!!!

 

250w is moer baie for a tank of that depth, if you want to keep sps's they will work lekker.

keep the mh about 30cm above the water,but it depends on want you want to keep

 

Keyaam - I will send you a PM now....

 

Jacques, Thanks for the PM.

In terms of lighting and tanks specs, what corals can I keep. Lanzo has mentioned it will be great for SPS which require alot of light. I was aiming at keeping one or two hammer corals with some SPS. The tank holds 214 litres approx. So the MH outways the one watt per litre concept. Help, need stocking 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!

 

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?

 

No - JUST GO AHEAD AND SHOW US YOUR CORALS NOW!

Awesome man! ?
BTW: What brand skimmer is it? Does it have a standard impeller pump or a needle wheel?

 

Jacques, its a red sea prizm pro skimmer HOB. When my tank is ready I will start a new thread dedicated to the full tank. The first lesson that I learnt was patience. Tank is running for its sixth week. Got all the equipment I need for now.

 

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... ;-)

 

18 blades:yeahdude:

 

yip go for lps and sps, sps higher up and the lps lower down.

sps like high flow and lps like medium flow, so put your (3-4 high rated)powerheads blowing around the top level of the tank were the sps are and the medium to low flow will be middle a bottom part.(plus this will give your reef a fuller look from bottum up)

 

THANKS LANZO

GOT THE FOLLOWING PUMPS.

1 x SEIO 820
1 X WM1 WAVEMAKER BOYU
1 x 1600LPH POWERHEAD
1 X 100 LPH POWERHEAD

the last two are temporary for water flow. will add another seio and wavemaker shortly

 

m1100 and one more wm1 will work leka with the m820 and the other w1

 

thanks for the advice

 

Where did u buy that light? builders warehouse?....lol
Im in need of one, but so far i've been told they start at 1500 a piece, didn't ask what size that was, i need a 250 cause my tank is around 80 deep.
