I've been planning to switch my 26g community to sand for a while now, and now I'm finally ready to order the Black Diamond Blasting Sand from tractor supply. I have a plan (I think) and I'd really like some feedback. I don't feel comfortable adding sand with fish in the tank, but I ALSO don't feel comfortable taking fish out of the tank. So I'm nervous. 1) Wash BDBS thoroughly in a bucket until water is clear. 2) Stop all tank equipment. Fill two buckets with tank water. 3) Put filter media in one bucket. 4) Carefully net fish into the second bucket. Power on the battery powered air pump. 5) Drain the tank until one-third of the water is left. 6) Scoop out gravel. Vacuum tank to get loose particles out of the water. 7) Put BDBS in a cup. Submerge the cup and carefully pour sand on tank bottom. Repeat. 8) Fill tank back up. Give sand time to settle. 9) Add filter media and fish back into the tank. I'd like some advice on taking fish out of the tank. Is it safe to leave them in the bucket for (possibly) two hours? Here's my stock. 1x platy 2x platy fry 1x guppy 1x endler 2x balloon molly 4x glofish tetras 5x cories 1x mystery snail 2x nerite snails I realize that some schools aren't completed and such, but that's because my tank has suffered losses in the past month. Has anybody ever taken fish out of their tank for long periods of time? Should I cover the bucket with cardboard to prevent jumping? Also, any advice to prevent clouding? I've never done sand before.
