BTA flow

[chewieee]

How much flow is needed for a BTA,

 

[Lance M.]

In general terms, I would say moderate probably at least 30x tank volume turnover.

I have about 40x turnover in my 20 gallon w/ two btas. One I have had for over a year and the other I have had for a month. They are doing great. The oldest is positioned so that half of the body is in direct water flow about 3 inches from an Aquaclear 20 (~125 gph).

Moderate, but you will find that the anemones will find the flow they like best by moving toward or away from the flow. I have 3 RBTAs and they are all different as to what flow they prefer. I had a single Koralia 4 in a 4 X 4 tub and that was too much flow in conjuction with the sump return. It was about 15X but since it was a tub without anything but an anemone in there it was really strong flow. I now have Koralia 2 and those are working great. If the flow is too strong the anemone will keep its tenacles really short.

do you worry about the nems getting caught in the koralias, or did you do something to nem-proof them?

sponges cover the intakes and are cleaned weekly to keep flow up.
