hello zp
i was thinking about water movement in my tank as i have 2 internal power heads used to create movement also i have my rena external.and air pump. currently i have my power heads 1 at each end of the tank is it a good idea to have water movement coming from 2directions in the tank?
also ive found that there is a few areas in the tank were uneaten food builds up?
prob a noob question but i cant remember would zebs use a cave that has water flow going into the direction if his cave
thanks
