    Shrimp seem to like it

    This is more an overall review since I've been trying really hard to get back to y'all! So shrimp have been hard to find and expensive. I want to thank who ever packed my lil friends an all the rest of you. My Zen Tank is looking so Cool now. It's jus shrimp and under water legos i.e. scuba guys sharks angle fish. My Dude Loves it.

    New to the game

    So I’m just starting this new tank, this is the first time I use caridina GH+ and so far it’s made everything easy, 1 pump and just testing the water every other day and it was able to establish the correct parameters. Happy to continue using it on this tanks journey

    Seems to be doing the trick

    I’m not exactly sure what to say here. I just set up my tank for caradina, and I’m in the process of having it cycle. So needless to say, I don’t have anything but snails occupying the tank. It’s super easy to use though with the pump. Test your water every hour as stated on the bottle to get to the levels you desire and go from there. No complaints so far. Thanks flip aquatics!

    Not what I expected

    This product took a lot of squirts to reach the expected hardness that I want in my shrimp tank. I would recommend sticking with other dry salt based products.
