Using a Freshwater tank for Saltwater

I am new to saltwater tanks.

I have a 150 gallon acrylic tank that I am currently using as a freshwater planted tank. I am in the process of taking the tank down to convert it to a saltwater tank.

Are there any special cleaning/disinfecting tips? Or any special DOs and DONTs?

No, not really.

Other than, "Don't scratch it!"

Seriously, simple cleaning with water should suffice, but if you are worried, you can use a 10% bleach solution soak, then rinse, then air dry.

People do this pretty often. The main concern is whatever treatment (especially those with copper) you had been using in the freshwater tank may have left residue. But a rinse with a water and bleach solution (light on the bleach, like a capful for a gallon or so) and drying it well should do the trick.

You were probably planning that, anyway. Some rinse further with RODI just to be extra cautious.

Good luck!

Welcome to RC, rainsong!

As stated above, there's not much to do, switching over to saltwater. Just a basic cleaning.

I have bounced back and forth with fresh and saltwater versions of my acrylic 180 gallon tank. Currently, I'm running a Planted Saltwater setup, combining what I learned from both sides of the hobby. My thread, "Weeds", down in the Macro Algae Section may interest you. Come by and check it out. Here's a taste:

As many naturalists and environmentalists have suggested, we should set aside our arrogance,
our desire to conquer and control everything, and walk hand in hand with Mother Nature. -Walter Adey
