Interesting question.

So your JBL 701 has a flow rate of 700L/h which would give a real flow rate (0.4 x flow rate) of 280L/h for your 150L that would be a turnover of 1.9 x per h

using this data: JBL e1502 would have an estimated real turnover of 3.7 x per hour. Aquael ultramax 1500 would have an estimated real turnover of 4.0 x per hour. So to get close to the fabled 10 x turnover you would need 2 of which ever one you choose when you decide to go high tech.

I used this bit of research I have been doing, it is no way finished and might not be precise or correct. Butt might help with an overview and stop you spending hours collating data. Hope you can read it?
