Aquarium Advice FINatic
Hey all, i was looking to acquire more live rock just for use in the occasional change in aquascape or use in future fragging, etc. I was wondering if i had a 1o gallon tank with just live sand and rock and whatever comes on the rock, could i keep this without a filter without needing to change the water weekly? assuming the rock is fully cured. how often would i need to change the water and has anyone done this?
