    Water hardness/softness

    Hello everyone, So seeing as I’ve been told that my water is soft at 38ppm, I’ve been scouring the internet looking for fish I may want down the road. Problem is, so many of the fish I find myself looking at want 45-60ppm or above (at least according to seriously fish). I don’t want to make any...

    Fiddler Crabs & Equipment

    I've been doing a ton of research on Fiddler Crabs and I've found some good stuff. One thing that is giving me high anxiety is not having the correct equipment. What are the most accurate tools to measure water gravity and water hardness? And salinity I guess? I've gathered a good amount of...

    What is going on with this tank

    It's Jan again - long story ahead, I know you love it: I recently purchased a new tank to break up a group of peaceful and aggressive Gourami's as well as most likely purchase a few new fish. So purchased a new 29 gal glass tank. It has a lovely heater I've been keeping at about 78 degrees, a...

    What is so important about water hardness?

    Before I started my first aquarium I did about 2 months of research - mainly reading books. My needs were simple I wanted a peaceful community tank. But it's not all about the fish. Anyway - all the books and online articles had extensive information on how to cycle your tank so I was quite...

    Why is my (soft) tap water becoming hard in the tank?

    New to this and new tank - after weeks of prep, finally have neon tetras in. Testing the water, all seems fine except for the water hardness, which is measuring at the hardest on the scale (180). We tested our tap water and this had a very soft measurement (20). We now have a new tank filter...
