I use 13mm on my fishroom airline system in a BIG loop above and below top 2 rows of tanks on 2 separate lines of tanks, one line 9 metres long and the other 6 metres long.

I have my two old Resun LP 100's fitted with new diaphragms and valves as emergency backups for my fishroom, and have hooked them up and tried them on both my Nexus 300 filter and my fishroom airline system. While they pump just enough air to get me out of trouble for the short term while I repair or replace one of my Evolution Aqua airtech 150 pumps, I would need to shut down quite a lot of outlets on the fishroom airline system, they just do not pump anywhere near the amount of air as the Airtech 150, particularly when you have a lot of 2 foot deep tanks as I do. Cheers, Doug

I use these in my fishroom from AOA, made by the same company that make the Nexus filters, made for ponds and very powerful, will pump up to 5.5metres depth and will do 130lpm at 1 metre depth. Uses 106 watts and according to box runs at <50 dba, I find them very quiet with little vibration. From your picture, you don't seem to have a lot of deep tanks, you may get away with one of these instead of 2 x LP00. http://www.aquariumproducts.com.au/catalogue_products.php?prodID=4022&catID=14

Yep, that's what you find when an enthusiastic hobbyist runs an aquarium shop instead of a corporation. We all need to be supporting guys like Andrew so they can continue to operate. Cheers, Doug
