i have about 70-90 of them there, i feed it daily for now hoping to see algae soon. Btw, i have mixed the powder with the tank water into a container and realized i mixed too much, can the excess solution be used tmr or day after?
I wouldn't use anything but fresh mix from powder. Not worth polluting the tank accidentally. Also, more is not better. If you over feed your system with shrimp in it and end up spiking the ammonia and starting a chain reaction of death. Slow and steady wins the race when you have shrimps in the tank. I only did heavy feeding on empty tanks that were being cycled and had no snails or shrimps in it.
