I recently switched to sand, an I noticed when fish swim by filter intakes an when eating an such they stir a bit up an some gets into the filter. ( i looked at filter pad.) Some could have been from when I put the new sand it. Tank was a little cloudy when I turned filters on. Is it bad to have sand in filtration? I got 2x marineland HOB with Bio wheel each rated over my tank. ( p's in my tank )
Is a little sand common?
