Added 20kg coral sand, filled it up let it sit for a couple of days and the salt finally arrived today. Warm day chucked a sicky, added the salt and started the sump
My custom PVC return :)
Ok this is my overflow, I m not really sure if this is the best way to do it, got the idea from a youtube clip, but he had longer pipe the width of the tank. fingers crossed don't know what problems it will cause me in the future....so far it does the job, very quite.
I m not too sure about this sump, aaaaaanyway....
