Too Much Flow?

[AndyS]

Hiya, new to this forum but have been reading for a good few months now.

I have a 10g cube and have recently replaced the stock pump with a maxijet 1200, i tried using this as a powerhead for an afternoon (cube has compartments at the back for pumps) in the main tank section and my clown was really struggling with the flow, also a lot of my substrate was moved.

I then did a bit of modding and have fitted the maxijet in the back middle section of the tank, with a tube attatching it to the original spray bar to the front, this has led to a much better flow and my clown and other tank inhabitants are coping much better with the flow, plus there is lots more water movement than before.

I was just wondering if there was such a thing as too much water flow, or have i just got a lazy clown

Great forum btw, wealth of information, provided me with most of the knowledge to get the tank up and running in the first place.

Welcome to TFF Andy!

It really depends on what your keeping. For the stock standard nano reef containing LPS and softies, 100x turnover is probably way in excess. For a bare bottom SPS nano, 100x turnover is probably something to aim at. If you figure out the value numerically, we can suggest a guide, but most if not all your creatures can cope with higher flow. As for the sand bed, you can just aim the powerhead/pump outlet to the surface in an attempt to stop too much sand being disturbed.

Agreed, 295gph in a 10g tank is only 29.5 times turnover. No problem ther at all

Thanks for the comments guys, i have mounted the maxijet at the back, connected to the front via a tube saving me a bit of space in the "main" aquarium. Flow seems much better after replacing the stock one, didnt realise how bad it was until i had tried the Maxijet. Will post pics when i can get my camera to hand.
