Well the other day, I changed my 10 gallon over to sand. Everything was fine.
No problems. Today, I did my 25 gallon. Did about a 60% change and almost left everyone in because they're kinda too big for my 10 gallon to hold while I'm waiting for everything to settle. I had one cory, 2 gold, my kissing gourami, and my clown pleco in a net to keep them separate from everyone else. This apparently was a bad idea. I had my 2 other golds, one cory, and my 2 angels in the water while I was taking the gravel and cleaning the water. I put the sand in about 5 and about 8:30, my golds were looking very miserable and my angels were pretty lethargic as well.
This may be due to my lack of any levels which I don't understand. My filter had water in it the whole time and I even left about a table spoon of the original gravel in the water while I poured the sand in.
Nothing was clearing up so I put some clarify in but that didn't do anything.
I took EVERYONE out (Which I wish I could have gotten video of because we had to use the colander. My angels are too big for my net.) and I put them in my 10 gallon. Everyone looks fine now and I've got the angels in with the guppies but everyone else is in a breeders net. EVERYONE is in my 10 gallon and like I said, doing GREAT, but my family is worried about what I'm gonna do. I need to get this fixed fast.
