Well guys I can assure you I am not going into pond business of any kind because I know I am no where near knowledgeable to help myself let alone anyone else!
I also understand all of the points made above about the help I am recieving. Bill has been helping me a great deal with this project and I will buy products from him in return for all the voluntary help he has given me! I am sure I could source the compressor he has recommended elsewhere concidering i have a lot of connections to industrial suppliers of many types of pumps and compressors but I would much rather buy from him in return for his help. If I could afford a vertex system and all the other projects my pond is needing this year I would probably talk to sue for suggestions but since I know that is out of the budget I dont feel right wasting her time to probe for info.
The one thing I wish there was is a good search engine for this forum, I really struggle to find information that I know has probably been posted a dozen times before on here and would really help me not have to ask all the dumb questions that I do on here...
