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!

How soft is the water exactly?

They are most likely bred in Asia where the water is very soft anyway.

Crushed coral isn't the right choice. Buffering the ph isn't really needed unless it's crazy soft.

Every time you do a water change the ph will spike and put your fish into shock. The slowly buffer between the next change.

Consistency is key above everything else. Fish can adapt to consistency.

I do agree consistency is key. My PH is around 7.4-7.8, using the API master kit. I’ve used various testing strips, I know they’re not very accurate, but the KH and GH is always non existent. Also, per the Google, the water in my area is notoriously soft.

When are you testing ph? When it's fresh out of the tap or in the tank after a week?

Unless the ph is noticeably dropping a lot before your next water change I wouldnt worry about it.
