Hi, I am new to the forum, I have had a small 500 gallon pond with just 2 ghost carp and 2 goldfish for nearly 10 years. Now I have purchased a 1100 gallon pond on EBay and also got the bits and bobs to go with it i.e. 4 bay filter, air pump, UV & pump and lots of pipe and gate valves. I want to get it set up an running andf then slowly introduce some more ghost koi. But I could do with some help with the plumbing.
