Soaking MP10 wet side for algae question

[aviator300]

My MP10 has been in my tank while trying to resolve a Bryopsis and Red Cyano outbreak for about 6 weeks now.

 

I took it out earlier this evening and found it covered in red slime and also Bryopsis growing all over it. What would be the best solution to soak it in after removing all the gunk I can by hand. I sure don't want it to carry bad stuff back to the tank once I get it all cleaned up.

 

I thought about posting this in the pest/algae forum but I hope to get some ideas quicker here.

I'd use vinegar.

vinegar is good, but if you have bryopsis you might want to consider bleach.
