[Repashy]

I'm looking to try Repashy foods for my guppies.
 

• Approx. how much do you feed a school of 10 guppies?
• Can/will it last 24-48hrs in a tank without causing water issues?
• any other pros/cons?

Looking for a way to be able to take long weekends, or be able to say to fish babysitter "just drop in 1 block per tank". type thing.

Thanks in advance.

Dave
