How do you kill this sponge?

[Leslie88]

I know it’s not algae, but it seemed appropriate in this forum.

How can you kill off this sponge? It’s in a clients tank and I want to kill it off. It’s so invasive. No idea why someone previously put it in.

It’s a 58 oceanic tank.

Thanks!

That way

Excise it, surgically. Messing with that in tank is asking for issues. If it's hard to access/ large tankers problems lol prognosis still the same, cut it out like a benign growth and you won't lose nontargets. Arrange rock expecting growback/follow up gardening

Dont kill it in tank

Take the tank apart and clean it. You can siphon out your clean 90g of water to reuse, then refill from that same water column

Lift the rock out alternatively, but access it in the air, directly.

Sponges can be hard to kill.
I’d cut it out and try to keep pieces as large as you can.
The. Dose coral snow and cut down on DOC and particulates and and carbon dosing and Aminos, phyto etc.

You can diy it too. Basically chalk.


Might need periodic treatments cuz Mother Nature rules.
