Eheim Compact And Diy Spraybar, Help.

[Nick16]

hi all, i want to purchase and eheim compact+ 2000 pump, (i have a compact 1000). The 1000 will not be good enough for my new large tank so i will need something bigger, hence the 2000. However i will be pumping from an 80L bin into the tank but i cant just pump it straight in as the substrate will get blown to pices and plants uprooted etc. I want to DIY a spraybar but i cant find any plastic ones around. (will need 5 or 6 20cm pieces)(and that are fairly cheap) i will also need a right angle spray bar connector so i can have spraybars on two sides of my tank joined up. (if you understand me?)
but i cannot find any single spraybars that i can buy or any connectors for that matter.

i have made a list of my questions for simplicity.

1. What size tubing fits the compact+ 2000? is it 16/22?
2. where can i get some spraybars
3. Where can i get spraybar connections
4. where can i get the clips and suckers to hold the spraybar to the side of the tank? (im sure AE used to sell them but i cant find them anymore!)
5. sorry for all the questions

i might just diy a spraybar out of the tubing that fits the +2000 (e.g drill it), but i will still need a right angle or 'L' connector so that i can have pipe at 90 degrees

i have trawled around but im stuck and dont know what to type in on ebay as i seem to just get internal filters come up!

any help would be super.
