Hi there I am still uncertain how I got into all this, but I ended up with a 1000 litre tank. Got all the basic equipment I hope to believe. Been told how to connect it all together and the basic function of each. Furthermore ... I selected a beautiful location to put the tank and spend the past three week-ends preparing. Now i am at the point to do the sump filter and the water ect .... And now I am uncertain how to go about everything.
