The tanks look great. Water changing must be a breeze with them so close to the sink!
Yes, no trouble at all. I just use a section of hose about 3' long and put it right into the sink. I think I need to buy some smaller hose though because it sucks out almost all the water before I can blink. Those shrimps had better hide!

The stand is DIY - I picked out the wood, planned it and did the finishing work, and my husband did all the cutting on the nice Hitachi miter saw he got last Father's Day, and got the base and canopy together and square for me.
