Hey guys, I was just researching an alternative to the common root tabs in the pet shops, and was at Bunnings and found Osmocote "Water Gardens & Aquatic Plants" - safe for fish, Feeds for 6 months, pellets. Just wondering if anyone has any personal experience with these. I picked these up for $6. Anyone with experience with these - or any other Osmocote products - please write in. Thanks jn advance.
