Creating flow

Could possibly introduce microbubbles, also makes salt creep like mad. Could you maybe try a hydor koralia? I think the magnet feture would enable you to put it on a cylindrical tank.

i never asked when i was told about not putting an airstone in a marine tank i guess thats because i was just trying to get the basics at the time i need to know what exactly makes micro bubbles bad anyway?

If you don't have some kind of surface water removal (to a sump), then an airstone in the tank will turn your tank into a full size protein skimmer. You'll have a good scum on the surface.

When I had my hex tank, I ran the return pump from the sump into a SQWD which split into two opposing outlets in the hex. Every 30 seconds or so, the current would change from clockwise to counterclockwise.

So you're saying a airstone in a cylinder tank isn't a bad idea?

I think he is joking with you. Using an airstine is not going to help with flow in your tank. There has to be a rock that you can hide a PH behind or hang one up high pointing downwards.

If you have a cylindrical tank, how about placing a powerhead down in the rock work with a vertical spraybar? You would need to deal with the cord somehow.. If your rock work went to the surface you could hide the cord and the spraybar that way. Depending on the size of the tank you might be able to put something bigger in there, a Mag or some other submersible pump.

You may be able to run it the opposite direction..power at the top of the tank..spraybar facing down.. Need to hide the whole thing in the rocks though, if possible.

Telford,

Welcome to Canreef by the way...Always glad to see a fellow Okanaganer on here.

As for creating flow, I'm pretty sure you could run Hydors as their mount is partially suction cup. I have a Hydor 4 that I'm not using right now that we could try with when I'm in Kelowna sometime. I know Hydor Nano's would work because mine is stuck to a curved surface right but the flow is so little that it would do nothing for you. You would need 10 of them to get anything really going. Tunze's are a hard cup mount and will not work for you.

I also don't see why a Seio wouldn't work for you either (it would just take a little modding to the suction cup mounts.

Whatever you decide, you want flow or cyano will become one of your big enemies.
