Hi, I am new to this site. I wanted to ask if anyone uses feeding rings? I have a 30 gallon community fresh tank with a aqua clear filter and a air stone. I feed them both flakes and frozen foods. Even though I turn the flow down on the filter the food swirls around too much and falls to the bottom before they get a chance to eat it. Will a feeding ring help or someother feeding device. Any suggestions??? I am glad I found this site and all the helpful information. Thanks, Brooksie
