175watt MH on a 20g?

[mythrenody]

I will be moving my 175watt MH light from my 55g onto my newly cycling 20g and moving the corals into it also. Would this be too much light?

yes, id say 100wtt wopuld be good. and dont move all your corals in to a freshly cyled tank. maybe a coral a week. starting 2 weeks after it cycles.

Got it,thans!

 

[mythrenody]

Oh and I was gonna replace the 10k bulb with a 20k if that would make any difference

Its not too much light but I recommend 150watts..because it did well on my 24gal nano.

Your 175 will be perfect, because it is mogul i think that it actually about the same power as a 150 HQI. If you decided to get a new light id go with a 250 HQI with a 14 or 20K bulb and hang it about 2 feet above the tank.

Your 175 watt will be just fine. I love the color of a 20,000 K; more blue and the colors really pop under it and fluoresce.
:joy:
