I have the marina version and I had to stop using this because the air pump design and water gurgling was too much.
Could that be because my pump was too strong?
I just set the same one up for my betta, and the inline airvalve controls splashing and volume pretty well. I have it screwed down quite a bit. Its a smallish air pump tho, but a bleeder valve would help a big pump.
If I decide to do another one, I'll be giving the Finnex a serious look
