I've had my 10 gallon for about 3 months now and am starting to notice my sand getting a little dirty, mostly fish waste it seems the filter cant pick up. Also the way I have my tank set up is a little difficult to vacuum the smaller spaces around some of the decorations with the vacuum I have as the intake is a little big. I'm looking into a better gravel vacuum with a smaller intake and adjustable flow to solve that but I also started co2 and have a carpet beginning to grow. What is the best way to vacuum through or around a carpet? Do products like Seachem Pristine or Seachem Purigen work to help with this?
