Questions
I have a 20 gallon fresh water tank, how much will I need?
Can this be used with an undergravel filter?
- Yes,I have a reverse flow undergravel filter in my saltwater tank and not only is the CaribSea functional but is very attractive.One note though,I had to rinse a few times to clear up the cloudiness as I used 60 lbs.

Is it good for real plants!
I have a 40 gallon fresh water tank with a very high pH/very basic. Will this coral help make the environment more acidic/lower the pH? Also, can it withstand being cleaned with an electrical vacuum cleaner?
- Crushed coral has buffering capability which is why it's used in saltwater tanks which requires a higher ph so it wouldn't make your freshwater tank more acidic. It's heavy so vacuuming with any device shouldn't be a problem.

I need sand that will raise my ph to 7.8-8.5 Will this sand do that and keep it there?
- It's crushed coral so it will raise your Ph bit it is not the same texture as and. More like gravel. You could put some in a mesh bag in the back of your filter for a more steady higher Ph.

Hello how many bags would I need for a 100 Gallon tank ?
- It depends on the dimensions of the tank since not all 100 gallon tanks are the same and also how thick do you want the substrate to be. Most likely you will need three bags.

Can this stuff be used in a refillable mineralizer for a R/O system, in order to put healthy minerals back into the water?
- I think it sounds good since RO water is acidic. It should get your Ph up.
