Just wondering. Pond dechlorinator comes in a BIG bottle for a cheap price compared to the little bottle with a big price for aquarium dechlorinator. The pond dechlorinator says "for outdoor use only." Is that a scam of the manufacturer to sell us more expensive stuff for aquariums?
im not really sure, because i havent used pond dechlorinator before. but i do know that on drs.fostersmith.com they have really big bottles of stress coat for a better value than buying all of the little bottles.
I do, I have done for months - I use Tetra's one, it treats 4 gallons with 1ml - very economical. Lasts me ages with the tanks, only trouble is if my pond level drops (and it has a lot lately, leaky waterfall) it doesn't last long - my pond is 900 gallons!
