the principle that the aqualifter works off of may not allow for an inline installation. you may be able to use something like the mazezzi that people use for co2 with a check valve behind it, so that water wont try to flow back into the aqualifter. i think that the filtration hose may have too much pressure inside and that it could prevent the aqualifter from pumping, besides it would be hard to measure in ml the output of solution as it will be mixed with water coming out of the spraybar.
okay, rather than measuring output, measure the input. you could use a graduated cylinder or similar filled with water, so that you can measure in ml what the aqualifter is pumping from the container, and into the aquarium. i am not convinced that this would work, however, because the effects of head pressure on this pump are so great, i really dont think it will be able to fight against filter hose pressure.
peristaltic pumps would be the answer for an inline installation. im in the process of a project, a very large glass eurobraced rimless tank and dont want any junk in the tank or tubes/cords rolling over the edges, so everything is going to be plumbed from the underneath, Tom Barr inspired, with fancy light hanging from above on emt conduit. this means everything will be connected inline, heater, autodosing, ect. so i will keep you posted and let you know what i come up with for hiding out the autodosing tubes.
right now im starting to think about running the aqualifter tube up along with the light cables, then finding a clever way to attatch and hide the tubing inside/behind the light fixture so that it will remain unseen, and letting the solution drip 10 inches from the fixture into the water. that way i dont have to figure out how to plumb autodosing inline.
my only concerns are that i dont want the fert mix hitting the water and splashing all over onto the glass, but i dont think that will be an issue.
