A little more done today.
I installed the last of the 600ltr vats, the cryptic/benthic zone.
Unfortunately because I had to lower the ceiling and raise the floor it left me with little room for access. Due to this I had to cut out some holes to make life a little easier. The water level in this vat will sit at about 34cm, the holes allow for an additional 10cm for when the surge fires.
The cryptic tank is fed via the sediment tank. This is where the flow is split, 50% to the cryptic zone and 50% to the mangrove tank.
Inside the vat the water is directed to the base of the tank where it will emerge under the live rock.
The 63mm standpipe will control the running level
For additional flow there will be a 3000lph CLS on this vat, the feed and outlet bulkheads are installed on the side.
Inside the tank is a simple manifold with 3 outlets to direct more flow upwards towards the rock.
I made some koi crate stands to sit the Live rock on
I picked out the smaller rocks I have, the ones that will be a little tedious to aquascape in the display and added those to the vat. I would estimate there is about 30kgs of rock.
