Cook, boil, freeze

[CoryDude]

I kept my mg levels at almost 2000 for nearly 3 months. The bryopsis would go away, but then return after the levels were brought back down. Or, I could have reintroduced some when adding new corals. As y'all know, there's never an easy answer in this hobby.

I pm'ed bill before I even posted this thread. He seems to be the resident expert in this subject.

I've frozen rock before with some success. But, it wasn't anything large scale like this project would be. I'd just put a piece or two in an old plastic grocery bag and leave it in the freezer for a few days. My wife hated it, but it seemed to work.

There's an algae killer for FW that kills pretty much all algaes. You'd have to search around for the threads though.

I think it was either algae killer or algae fix.

OH and it was used in a FBR (full blown reef!)

I personally thought the guy was STUPIDDDDDDDD but he didn't lose anything.

Interesting discussion...

I have read articles about proper disposal of macroalgaes in order to avoid introducing them into our ecosystems, etc. that swear freezing them is the only way to go. I think it would be worth a try.

Wow. Wish I had known that! I hope mine don't come back after drying out/bleaching

Whew I just looked up safe disposal procedure for macro:

As responsible aquarists, we need to remember that our fish are not the only creatures in our care that can damage an ecosystem. It is very simple to add bleach to old water during maintenance to kill organisms from the tank, and to kill any harvested macroalgae before pouring the tank water down the drain. Or, if you're opposed to bleach, freezing the alga, or leaving it out to dry completely, is also effective.

So I am hoping I am good. I would think drying should destroy the cells much like freezing would.

Karin, what parts water to bleach ratio did you use?

So far I'm thinking I'll dry the rock, freeze it, then soak in a bleach solution and then finally rinse and dry again before adding to the new tank.

here's a thread where bstreep mentions his recipe:

I think I used more than that. Don't remember. It was burn your eyes stinky though -that kind of ratio...
