Every time i do my weekly water change for my 5 gallon tank, i use a gravel vacuum to get uneaten fish food out of the gravel. However, the gravel that i have is very fine black quartz, and the finest particles always get sucked up first and clog the living daylights out of the vacuum and it turns out sucking more water than dirt. Its very annoying and more time consuming that it needs to be. Any tips?
The only time he moves if hes half buried in gravel or if the lights off
