Last night around 2 am I noticed my tank (37 gal) is leaking!! It's definitely coming from the bottom of the tank and my carpet was soaked. I'm not going to try and repair the tank. I'm going to buy a new one. It's a good excuse now because I've always hated how tall the tank is, so I think now I'll get a 38 gallon and a new, nicer stand. Good thing it's a slow leak, because I cannot get to the store until tonight, or maybe even tomorrow. Here's my question - I'm going to put in new sand. I feel like stirring up the existing sand is going to cause a giant nutrient explosion. Do you think that's a bad idea, to add new sand? I was planning on doing 30 pounds "dead" and 10 pounds "live." I'll be using the same rock, after a good scrubbing. I also want to put on a new filter (this tank is skimmerless). Can I do that? Or will that be too much of a shock? I plan on putting the fish and rock into a giant tub with some of the tank water. I do plan on reusing the same water. Because I don't have time to make 35ish gallons of new water! Wish my fishies luck!!!
