Too Much Flow???? Please Assist!

aykim2188 · 03/31/2010, 12:06 PM

Greetings!

I have a 20 Gallon Tall and right now I have two powerheads in it. I have a Koralia Nano (240 gph) and an aqueon powerhead (500gph). I'm worried that this is too much flow and I was wondering if I should change my aqueon to another Koralia nano so that I would have 480gph instead of 740gph. Also I am still not sure where I should place the powerheads. I have one points up from the side and one pointing directly across to the other side and it is placed much lower on the tank. Please help! Thank you.

Blowing powerheads into the glass and upwards to the surface (not necesarily at the same time) is a good way to create random flow and ripple the water surface for good air exchange.

As for "too much" you'll have people running anywhere from 10x to 100x or more so it's really a matter of what you want to keep.

Just don't blow right on any corals, although there are some like like brutually hard flow you don't want to blow the tissue off the skeleton!

I have a 29 gallon and have a koralia 1 and koralia 2 and flow from my HOB for over a total of 1000gph! My corals and anemone love it. Besides 500 to 480 won't make much of a difference. I have mine on opposite sides of the tank pointing slighty to the middle and slightly down

Sounds like a good flowing tank, I wouldn't worry about it!

I agree that you are probably good. As long as you aren't blowing your rocks into the corner of the tank I'd go with it. Good air exchance is important not only for general water quality but to lessen the chance of algae and cyno bacteria.

Thanks for everyone's comments.

The reason I say this is because my two clownfish stay in only one spot of the whole tan -.-?

As long as the clowns are eating, don't worry about them...they may be acclimating to the tank if you haven't had them long and, they will often pick an area in the tank as "their" territory :-)

+1 I have a 125 gallon tank and they stay in the back right corner 90% of the time. It's their territory.

as implied, this is what clownfish do. they pick a location as their home, and they seldom venture far off. this has nothing to do with flow, and everything to do with the nature of the fish.

Ah i see i see. Thanks!

I have a 120 with two koralia 2s pointed at the top of the water and two koralia 4s pointed at the front glass of my tank i have great flow and my clarckiis stay on the left side of my tank.I don't think it's a flow prob just give them time.

aykim2188 · 04/11/2010, 11:18 PM

thanks! I will keep both powerheads

The time when you have too much flow is when corals don't open up or if their polyps are waving in the currents too aggressively.
