Keri,sorry if i came off argumentiitive,it was late last night when i typed that.You have a pretty low aquascape right now,as it grows you'll be able to put those SEIOS behind the aquascape where there flow is easy to break up.Slowing them down might be a good option for you then if you tried everything else.One that Xenia attaches itself,you'll be fine though with a good flow of water blowing on them.
