sure bro, but will post it after the modifications done. need to fabricate 15mm fittings as well as put some layers of perforated sheets inside...
Alright thanks! Please include also photos of your perforation sheets. What do you have in mind, make an adaptor and use two sets of hoses, 15mm and the smaller ones( splits of 4 hoses)? Or have the fittings be adjusted to 15mm so there will be two long hoses instead?
