Im just kind of toying around with an idea of setting up a 40 gallon breeder and converting a 20 gallon tank into a sump filtration system.
This may or may not happen, and if it does happen it wont be for a while.
Just for fun, I was plugging my fish stocking into AqAdvisor and realized that I had no idea what to put down for filtration. How does one figure out what the filtration capacity is for a DIY sump filter? Is it more or less based on the gph
of the return pump, or does the water volume factor in as well.
Another question: When considering fish stocking, do I use the combined volume of the main tank and the sump, or just the main tank? Im thinking about the number of fish, not the size of the fish.
