I seen on Youtube many people are doing 50/50 bleach and water solution and letting their decor/ nets sit in that for a few minutes keep in mind this could reduce the integrity of your nets over time making them ware and fray quicker. Then wiping your tank down with a similar bleach solution and rinsing everything( tank, nets,decor) really well in declorinated water( use your tank declorinator for this). I have used a vinegar solution to clean tanks before (smells a little) but i dont know if this kills every disease, i used it to get rid of white bugs everywhere that a wild caught bass brang in. I heard people use
hydrogen peroxide, isopropyl alcohol solution. Ive heard people use a heavy salt concentration with water, this one could get messy with salt stains everywhere so you would have to rinse really well.
