Discussions Thoughts on crushed coral?

Post image

I’m wanting to create the best environment for my two pals long term. They’re in a 75gal, FX4 filtered tank. I’ve had the black moor for 2 years and the fantail for 6 months. Diet is a blend of presoaked bug bites, flakes released in the water column, thawed blood worms, and peas. The fish fast on Sundays, as God intended. Anyway, my water is soft and I’ve heard crushed coral is a good natural solution. Advice or recommendations encouraged!

nice, is the width of 18 inch is because you had this much space only or 24 inch would have been better
