BTA and Powerheads (Koralia)

[monicaswizzle]

Don't have a BTA yet, but I am thinking of getting one. I have read that BTA can often wander into powerheads so that they should not share the same tank, which makes sufficient flow rates for the BTA challenging.

In addition to the return pump from my sump (which is attached to a wave maker that alternates the flow), I use five Hydor Koralia pump/powerheads that range in rated flow from 400 gph to 850 gph. (90 gallon tank). The Koralia is designed differently from the average powerhead and draws water from a 360-degree area around the impeller, which sits inside a round "basket" of plastic with a larger set of openings on the water delivery end. I assume that still might attract a BTA and provide too much suction for them to avoid contact with the impeller, but I am not sure. Does anyone have experience keeping BTA in a tank with Koralia pump/powerheads?

My BTA never really moved more then a couple of inches. Never even comes close to my koralia 4s. As long as your water is stable and your lighting is sufficient the nem shouldnt move around much.

But cover them up just to be sure...do a search, there's a thread in which someone used a pre-formed "egg" shape of cross stitch mesh.

Don't believe the hype! Even seemingly happy anemones will go on a stroll. Cover them powerheads .... better yet ditch them completely and move water with the return or a closed loop.

But closed loop intakes can be just as dangerous.
