thinking about trying to make one. What is the bleed valve you used? I want to look a little more into this.
The Bleed Valve is the button that is on top of the House filter, some people
will remove this and use it as there point of co2 input, I left my intact it makes filling the reactor up fast when my filter is full of water and the return is under water.
Jim got a pic of your sump set-up, was thinking of similar set-up for a big 180g tank. Will be breaking down my tank by the end of this month for our big move to our new house.
