Questions about marine setup?

Can you have to much powerhead? Like more powerful then the 200 gph, instead I get 2 150 gph.

I seen the difference on liveaquaria.com and true percula have way more black where as the ocellios dont have a lot of black. Can I just fit a pair and thats it or can more fish fit?

What size tank? Is it the 20 long in your signature? If so, yes, you can fit another small fish, like a firefish or small goby.

I'm sorry, I don't know about powerheads.

Thats cool I can fit another fish.

in a small 20 gal 2 would be ok directed at each other to creat more water motion and disturbance a big one would be ok but would not creat the same movement in the water

technically, i would say you could have too much current. If your fish are too small and can't swim right, you may have too much flow Other than that, some people will put 20x's the flow in their aquariums so I wouldn't worry too much

Ill get 2 of the lowest powerheads I can find. If not Ill get a 200 gph.

does anyone have a lcue how an air stone would be anything but good for an SW system, assumeing its not bubbleing water up out of the tank and onto an electrical outlet or doing some other thing of that sort.

How many times a week do you have to make waterchanges in a sw tank?

There are people with established reef tanks that only change water every 3 months or so
