Looking to do a mail in water test. I'm having issues with my one of my newer tanks and can not nail it down on a simple test. For some reason my when I put frogspawn, hammers, brains in they close up in about 2 or three days. I put a brain in yesterday and just looked amazing! Swelled up just like it's supposed to. This morning still nice and puffed up, but all the mouths are open. I also noticed my turbo snails when I put them first in we're very active. And the last three or four days have been very lethargic. I have hermit crabs that are running around the tank like they're supposed to as well as a cleaner shrimp. They have been in there a while now and show no symptoms of anything wrong. So I'm thinking of going ahead and sending a water test in to get a closer look. What's the best one? Thanks
