Chemiclean Shelf Life

[piranhaman00]

With chemiclean being an antibiotic I figure it has a shorter shelf life , similar to Abx meds for fish. I bought some in November 2020, is it worth using or should I ditch it? Three years old leads me to think it’s bad. It does not have expiry infor and can’t find anything on web about this.

Is it liquid or dry? Dry chemicals last longer.

It’s the dry version

It's probably OK, but I cannot know for sure.

I bought mine (powder) more 2 years ago and its been in a ziplock baggie on the shelf since then, and I used it just 3 weeks ago, it worked perfectly.

How did you dose it?

How did you dose it?

I just followed the instructions, one spoon per 10 gallons. I have 40 gallon tank, so 4 spoons into a glass with saltwater to mix it, then into the tank with an airstone, then water change 48 hours later, it worked perfectly, I was pleased with the result.
