So I have a 28g tank and have been thinking about switching from gravel to pfs. I've been having problems keeping the nitrate levels down in my tank and I think part of the problem could be solved if I had an easier to clean substrate. (I'm not overstocked and I only feed a small pinch every other day. I do pwc's every week of almost 80%. My tap water is nitrate free and I just can't figure out why the nitrates are still around 40 before each weekly pwc) I've heard that to clean pfs all you have to do is swirl the sand around with the vacuum and the waste will come out because it's just sitting on the top. Any thoughts on this?
