I have a Hawkeye above-water power filter in my 5 gallon hex tank.
In the tank is a Betta and a Golden Mystery Snail.
When I first got the tank, I baffled it with a water bottle. I tried it once and then again with a new bottle. The current seemed a bit too strong, so I tried doing a sponge baffle. I bought a car-washing sponge from my local Dollar Store and while it worked for the first day, it really isn't doing its job anymore. The betta appears to be struggling a lot.
Are there any other baffling methods? Or was my big mistake in buying the wrong type of sponge?
I really want a happy, healthy fish!
