Ok, due to insufficient water flow in my 29g planted shrimp tank (film on everything, no movement in plants) i did away with air pump and installed a fluval ac 70. i swapped out bio stones about 20% from estabished tank and added part of the sponge from the sponge filter as a pre-filter on the ac70 and have it on slowest flow settting. Would it still be possible to have shrimp fry survive or fry of any kind?
