In search of the best pick...

I'm getting ready to order some reagent for my hanna copper checker and to qualify for free shipping I need to add more to my cart...

In your mind what has been the most useful <$20 purchase you have made for your tank....

Happy reefing everyone!

Haha! I was doing this yesterday and the alk reagent was my add-on for free shipping

How about your other tests? You can get other refills.

Too funny. Yeah I was going to just double the amount of reagent but thought I would ask to see if there is any brilliant add on I have missed along the way.
