First read this short after posting. Noted that a few of the master growers checked in and did not comment. So, could not post, as I felt the first post deserved comments. Guppyponics took me by surprise. I've had aquariums and it seemed I used charcoal filters in the water, but wanted to hear from the pros here! This will be interesting, at best! I personally, think, you may just end up with some very happy fish or buds that may very well taste great 'deep fried' with the fish! Good luck, will watch this interesting grow! pr
