Freshwater Dip for Macros?

[Willj626]

I am setting up a macro display tank and I'm concerned about pests like flat worms and hydroids and such. Would a freshwater dip on Macroalgae be effective in removing any pests they may harbor? Would a freshwater dip harm the macros? If not how long could I leave them in? Is there some additive I should mix into the freshwater dip?
Thanks for any advice.

I had a marine macroalgae tank some years back. I really enjoyed it too. I don't know about freshwater dips. But, in my case, I never did any, and I didn't run into any pest issues. So, good luck with your tank.
