So I found some flatworms in my 24 gallon Cardiff, and I know from online research that they'll breed like rabbits if left unattended. I also read they like low flow areas, and since I was going to ask if my tank had enough flow in it I figured I'd kill two birds with one stone.
I have two Hydor Koralia Nano 240s in a bullet-shaped tank. One is pointed facing left across the flat back of the tank near the bottom. The other is facing right and is at the top of the tank near the middle of the tank's length. I have three returns facing towards the surface, opposite the highest Koralia, and one pushing water towards the highest Koralia. Overall the water movement is counter-clockwise, but with some variance from the return pumps. That is, the water is not constantly being pushed in one direction.
Is this enough flow or should I order a Nano 425? All my corals seem to be fine with the flow I have (all LPS
and softies), and have grown larger/more heads.
The flatworms are in an area where I can't easily reach with siphons, plus my rock is full of crevices and hide-aways. My stock level is full so I can't add any fish in. Should I just buckle down and get some Flatworm eXit and nail this problem before it springs up or should I try increasing my flow first? I'm worried that even if I increase the flow the flatworms will hide in the rocks, but is that a bad thing? As long as they don't touch my corals, right?
I appreciate any and all help!
(I should add I don't really plan on getting SPS
anytime soon, and if I did they'd have a nice spot right in front of a Koralia for their super flow needs.)
