Hello. Since asking for help with my tank mates previously I have fixed my stocking issues. I have a 30 gallon cube style tank (20x20x18) and am currently now running a fluval 70 filter on the lowest flow rate I can have. The stock is one adult angel, 4 glofish, 7 Cory cats (panda). I will be adding in a few more glofish or guppies and a dwarf flame gourami. My question is that being the tank is a cube style is the flow from the 70g filer too much "current" for the tank? I do have a 50g hob that I can use if this is too much. Any suggestions would be appreciated.
