Building the fish room and tanks putting the last bit of pipework

Fish tanks for the new fish room nearly finished just putting the last bit of pipework in, then we can connect to the system.

It seems to have taken for ever to get this far but now on the last stretch.Just have the last bit of pipework to do then I can connect to the system and balance the water flow. I have already prepped the filter box,s so the bacteria should be growing nicely.
