Safe for cassette toilets?

Hello, This is an enzyme-based holding tank treatment, which means it's safe to use in any type of holding tank (RV, Marine, truck) and in septic systems. Thank you

Can it be used in gray and black tanks the same way?

We really don't know about the use/purpose in the Gray tank, definitely in the black tank. Why not just something like Dawn dish detergent in the Gray tank? Just a thought, it's a good degreaser.

This product uses 8oz single use bottles and another company has 4oz single use bottles. Which do you need?

My tank is 50+ gallons. I tried the 4oz version with poor results. Switched to the 8oz bottle and it works just fine.
