So we have drained the pond and acid washed the plaster after letting it cure for a couple of weeks.
Nothing seems to be leaking and pond water level held up nicely. Air diffuser are in place and working nicely as well.
Refilled with meter on the hose and it came out to a little over 5,100 gallons
Making some final tweaks to the pumps and installing the vortex inner screen basket system and it's time for fish.
Let me get some landscaping and the low voltage light system in over the next few weeks (if it will ever quit raining) and I will post up a bunch of pics of the final product.
