Okay so here's the deal. My tanks been up roughly 2 years now. It's a 120 with a 40b sump with fuge chamber with rock and chaeto in the fuge running a skimmer and a UV. Now my tank is admittedly kinda overstocked. If I wanted to change my sand to something I don't hate would i have a significant risk a crash if I suction out the thick ugly sand I have so I can replace with a sand that doesn't make me hate looking at my tank?
Thanks in advance!
