I STILL want to change the substrates in my 10 and 25 gallon tanks, and I do apologize if this seems like a repost, but last time things weren't very clear (and the forum gives me some 225 day old message).
First off, I don't want to scrap my tanks. I cannot afford to start over. I would be SO pissed if I had to give away my possibly prize winning angels. I cannot explain how pissed I would be.
What I am thinking is, while doing my 10 gallon, place my 10 gallon inhabitants in my breeder traps and put them in the 25 while I'm changing the substrate in the 10. I would leave a thin layer of rocks on the bottom of the tank or mix about 2 cups of it in with the sand. After the water has settled and I've gotten everything placed back, I can put everyone back in. I would obviously do a water change just to avoid splashing and an ass kicking from my mom for getting water on the credenza.
I've actually done this dozens of times, but don't tell her. I wiped it up and I clean it up when it gets dropped food.
With the 25 gallon, everyone is pretty big and knows my hands. Plus, it's a larger space to work with so I'm pretty sure I wouldn't have to take anyone out BUT this would take longer BECAUSE I'm not taking them out.
How fesable does this sound to you guys?
I'd also appreciate any stories on your experiences with doing this.
