New Weird Sediment...Ideas?

[Reach4]

how do I increase the backwash to 8.1 gpm when from what I'm seeing the fleck 5600sxt only goes to 5 gpm! (why do they sell it like this!)

5600 is the wrong thing for KL and a 10 inch tank. It's close. What you should try next is removing the BLFC washer, and do your measurement again.

There was a really good thread on this, that I might find. https://terrylove.com/forums/index....a-replacement-and-backflow-rate-issues.87918/ is good too.

Watch the pressure gauge during the backwash, and make sure it stays above 30 psi.

A 3/4 inch drain line may be worthwhile, or at least make sure your 1/2 inch is not restricted. It really should be 3/4, increasing as you exit the valve.

The maximum drain flow rate for a Fleck 5600 is 7 GPM. To max out the drain flow rate to maximize the Backwash rate, remove the Drain Line Flow Control restrictor (DLFC).

Thank you. I contacted the place that sells that combo (aquascience) and their technicians swore up and down that the fleck 5600sxt supports up to 15 gpm. They are sending me at no cost the tool to remove that little part since I couldn't get it with a screwdriver and a washer for 8gpm. Once I can get it out I'll try again with the washer they send and if I don't get the expansion I'll try it without any washer as at all. Here's hoping! I'm guessing I'm up a creek if it doesn't work
