Currently have a 74 gallon column tank cycling that I would like to add a few SA Leaf Fish to the top water column of the tank. I have a Ehiem 350 canister which is rated for that size tank. Beacuse it is a column tank it doesn’t have the length of a standard size aquarium. As such, it seems as though the water movement at the top of the tank from the spray bar is “excessive”. Since the Ehiem’s flow rate can not be adjusted and the Leaf Fish do not like turbulence, Any suggestions on how to lower the flow rate? Someone at the LFS suggested drilling more holes in the spraybar facing down. Thoughts?
