Fluval Flex 15: How many gallons for stocking?
Hi, all! I have a nicely planted Fluval Flex 15 that I'm just loving. I'd like to add some more fish to it using AQAdvisor, but because the Flex has about 3 gallons of its water as sump space, I'm not sure how many gallons to count it as. Does sump space count? Does it count only partially? Not at all? While it obviously doesn't create more space for the fish, it surely helps with bioload?
I'd love to hear your thoughts and experiences!
