You building your own sump? ..............Frank

The sump has been built and I am having to modify it by adding an extra
chamber to enable the DSB to be built up. Unfortunately the person who built
it didn't listen to what I asked and the water flow is down, up, down, up.
Nothing major, the glass for the extra panel arrived yesterday, so when I am
ready to add the tank connectors and the other small pieces of glass in the
aquarium, I shall break open the silicon.
