I've decided to post this thread as I was asked to elaborate on my air system & I didn't want to hijack someone else's thread, lol :encouragement: So here it is, I have a LP40 & I use heavy duty irrigation hose to make loops around the lower side of each shelf, then I drop airlines down through a 4mm tap, the advantages of doing it this way is that you can drop an airline where ever you need it & the main air hose is above the tank so no chance of siphoning back to the pump & slowly emptying your tanks. The reason I do complete loops around the under side of each shelf is to balance the system, you get an even pressure all the way round the system. Now I haven't done this yet but I'm hoping to do it soon but if you get a short length(about 500mm) of 100mm PVC pipe & place this in the system just after the pump, this will provide a reservoir which will help reduce back pressure into the pump if you aren't using enough air & help keep the pressure constant, hope you all enjoy the pics :encouragement:
This starts at the pump
Then travels up the support of the stand to a T piece
Then joins into the loop under the shelf(I secured it with every mans best tool, gaffa tape)
As you can see, I just punch hole anywhere & drop an airline
