Well my trouble started by my own stupidity.....of course. I went to do a water change on my 20 gal and forgot to power off the top-off. Do you see the problem??? I started siphoning detritus and didn't pay attention to the water filling back into the sump. Fortunatley I have my top--off water in a 5 gal bucket and not hooked directly to the ro-di. When I realized what was happening I went to un--plug the top-off and got my return pump instead. Error #2.
That's when Murphy's law came into play. The suction cups holding the top-off float switch came loose. I pulled the fill tube out of the sump and put it in a nearby bucket. I got the return pump plugged in before the sump overflowed. While watching the sump, the fill tube flipped out of the bucket and finished draining the last gallon of ro water on the carpet. My salinity changed dramatically and therefore I had to do a massive water change to correct it. Luckily all corals and livestock survived.
Needless to say, I have since marked all power supply cords and siliconed the top-off suction cups to the sump. I then practiced walking and chewing gum at the same time .
