Hello all, I have finally finished piping and filling my 300 gallon. I got lucky, as this was a freebe tank, the guy didn't want it anymore, I still need to clean the outside. The stand is made of 4x4's with 2x4s for bracing. The top part of the stand is laminated plywood @ 3in thick on edge. I rounded up some bulkheads and plumbed with PVC and tubing. I filled it and checked for leaks, so far so good.
I ended up putting a valve for each filling zone, and it has came in handy, as i can dial it in just right so sump doesn't drain faster than the tank and supply it. I put a check valve right after the pump so it wouldn't backflow if the power failed. The sump looks to be a little small for the size of tank, but it doesn't overflow.
Last night, the pump started making a bad noise, i went to check it, and the impeller was totally shot, pieces were pulling apart, so i got ordered a new one. The pump is a pondmaster model 24. I was very happy at the power consumption, however i found out something odd, with all the valves open, the pump consumes more power than with them closed down. Full open pulls around 170 watts, where as reduced to the flow i am looking for, it pulls about 127w.
Not sure what to put in it yet, the wife is thinking of pacus or other other South Americans.
I am not new to fish, but new to large tanks, we currently have a 70, 55, 29, several 10's and a older walmart MARS system.
I also started a thread way back, but didn't get back to it because of our move. That tank is still in the garage, waiting to be put to use. Its a 8'x4'x4'. (Thinking its 1000 gal) I'll get back on that thread and post some pics. That thing was so dang heavy, it tipped my tractor up trying to move it, hence my user name of Kubota
So, glad to be back, I have always enjoyed reading the forums!
