gravity feed question
gravity feed question
Ok, got my new reeflo today (thanks cweder), hooked it up to one side of my dual overflow via gravity feed, and openned the valve. My issue is that the gravity feed is not constant, seems to slightly increase and decrease, so the level in the cup can go up or down by an inch or 2 over the course of a 1/2 hour (overflowed into the collection cup once) - this unit has the gate valve mod on the outflow, so how are you supposed to keep the level constant with a gravity fed unit?
This may be important, I am in the process of upgrading my tank, and the current setup is only temporary and the flow down this side of the overflow currently is only about 200 GPH (I know I need more for the skimmer, so this might be part of the constant level issue?)
Any help appreciated,
Mark
