So i have a 20 gallon High with a modded Aquaclear 70 as my filtration. The tank has been up and running for almost 3 months now and my water has stayed cloudy for about a month and a half. I was told i would probably need a protein skimmer. The thing is i already have the big Aquaclear the heater and powerhead all in there and dont want to have another huge thing hanging in my tank, its just not visually appealing to me. So my question to you guys is what is the smallest HOB skimmer i could get? Thanks
