Well, im trying to make a DIY spray bar for the betta tank and i got some garden hose, how do i dis-infect it, i just washed it unbder warm water, this is obviously not enough. Is a hand-sanitiser dangerous?
You can buy pond disinfectant from most garden centres. I use this on nets and my gravel vac every week after use. Just pop it in a bucket with the desired amount of pond disinfectant then rinse thoroughly after.
Use the cheapest chlorine bleach that you can find at the store, the one with no sweet smells added or anything of the sort. The only active ingredient should be a dilute solution of sodium hypochlorite.
