............some bad news, as I'm posting on a seperate topic about it but in a nutshell,,, had microbubbles and tried redoing some plumbing and I bought a big yellow sponge from walmart,,, wrapped it around my drain exit so the water would flow through the sponge breaking down the bubbles... worked for a while.... well yesterday I noticed my tank was cloudy and a weird color... thought nothing of it,,,, got home today, tank was pure yellow... I was like are you freaking kidding me,,,, yellow sponge died my water yellow..... so I took the sponge off did a 30g change, and am awaiting the morning to see how its going, I didn't want to do a much bigger change, and actually couldn't as thats all the r/o I had made.... so that ruined my night =/
