Here we go. It looks like I need to lower the three entrances from the bottom drains in the filter about 20 cm. I also need to lower the entrance to the skimmers. They're a little bit too high up. No other major problems though.
It's not that I'm so patient. I haven't been able to run the bog filer yet because we've been playing around with tube levels in relation to the water levels.
Now for the mis-calculations. We didn't figure the water level correctly in the filter and we have to lower the inlets from the bottom drains. While we're at it we need to install the third gate valve. Some how my third one that I brought from the states disappeared.
I have the intake for the external pump and a submersible pump in the filer.
Here's a look at the filter. I've got 4 rows of filter brushes them various grades of filter mating. The maroon layers are scrubby pads to take out the fine particles. I also bought some filter felt that I'll place in there some where.
We lowered the entrance level of the skimmers to be able to take in more water. Just in case.
