how do you know 25 is the max

i dont, that is what i think the maximum that I would go ;) (see below quote), as i dont see the point, all i am bothered about is for my plants to grow, which they do well enough with just 10x, 32x is just over the top IMO ;)

Each to their own though...

I think George with 25x is the max i would go

Nice to hear from you, George.
That's some flow, can't wait to see it all (especailly the new lighting system).
I have a Superfish Pro 1. That one is rated at 600lph, although doesn't look like it.... You don't see many of these filters being used, glad you've opted for one :)

Thanks, Fred.

Let's not get too concerned with actual turnover rates. Truth is, most of us lose a significant amount of flow through in-line heaters, CO2 reactors, filter media etc. etc.

I may actually get around to actually measuring my flow rates one day...

How would you measure the flow George, just out of interest?

bit of a guess, but i would get 1 tank bigger than an other side by side. inlet in one out let in other switch on pump some water for a period of time. measure water in small tank,how much water-how much time to pump that water , do maths....hey presto.

i would go larger than a 1 litre jug for more accuracy. give yourself a fighting chance at getting a correct measurement.

Just read throught this. and Use a 10l Bucket with mesurement on it. this will give a long enough test run. also i would do it 2-3 times to get an acurate result. as a couple of seconds difference ould make up to 8-10 lPH Difference. i know its not allow but its inaccurate.

Sounds good to me. I'd also try and get all the inlet and outlet tubes at the same height that they would be when in service. That way you are covering for any flow loss due to head height (I think that is the correct phrase). Might be easier said than done though!

agree downward water pressure on the upflow would slow the rate alot.
