;)Hi all,im new on the site,right this is about water fed systems,the main topic is the water filtering,if any of you already use a system have you made one up yourselves or bought it from a window cleaning supplier?,ive found that it is very expensive to buy one already made from a window cleaning supplier,so i did some research and it is a similar set up as marine fish systems,so does anyone know or have set up their own system far cheaper than it would cost to buy one outright? cheers for any info
