Crushed Coral - Is it sustainable?

I was talking to a fellow TPT'er about peat and she mentioned that peat, contrary to public perception, is not renewable (in fact, its much closer to a fossil fuel) and is not harvested sustainably.

That brought the conversation to crushed coral. I know its made of coral skeletons, but where does it generally come from? Harvested? Farmed? Collected?

If anyone's got thoughts on sustainability in this hobby, I'd love to hear them.

Like all things in this hobby, some are sustainable and some are not. It's really up to the end user to determine whether a product they're buying suits them on all fronts.

I've found that many manufacturers have detailed information about collection or sustainability (specifically when it comes to "live" sand on the reef side of this hobby) about their products on their websites if it's not on their packaging.

Yes, Peat is Mined, most of it comes from Canada.

The use of Peat in Gardening is a rather hotly debated topic. There are renewable options such are Oak Leaves that offer similar benefits.

Here I'll "resurrecting" a Melted Crypt in 25% dirt /75% Oak Leaf litter.

I believe there are ancient Coral deposits that are harvested in Florida? Oster shells are a renewable option for Crusted Coral. There are alternatives if one simply looks.

I salute your Moral Compass I got out of Salt/Reef keeping 20 years ago due to destruction of habitat by collectors.

Considering the rate of decline of coral due to rising sea temps and the poaching of wild corals for profit, crushed coral seems to further fuel the exploitation of this environment. I'll personally turn to gh booster and baking soda to raise my gh and kh as these tend to dose better in more controllable amounts with more predictable results.

I don't know where it generally comes from, but I remember seeing places places in Florida far inland where all of the ground was just old crushed coral. It wouldn't harm the ocean much to quarry that material.

Somebody should manufacture and sell a consistent, well-composted shredded bark product as an alternative to peat. When I have used it before composted bark works as well as or better than peat in potting mixes. It's surprising that there are hardly any commercial products like that on the market.
