No, I did the salt, too, honest!

But the only reason I remembered it was that the bucket of RIT was foaming so bad with the air stones and the laundry detergent they suggest, I had to add it to kill the suds! LOL

Someone mentioned there are two types of canopies...lexan or polycarbonate and one would work with RIT and the other wouldn't...

I think I got "the other" LOL
