Just wondering... I'd like to test ammonia level in my tank, but I don't have the test kit yet.. local lfs don't have them.. need to find somewhere else.. so wondering whether any one knows how to DIY the test?
I would wait for the test kit. The components in an ammonia test kit are contact hazardous plus it would be very tough to calibrate IMHO. 2 part solution: part 1: 90% polyethylene glycol and 10% sodium salicylate, part 2 10% sodium hydroxide and 1% sodium hypochlorite.
