just received my eheim pro 3e and have a couple of questions. currently i have the spray bar pointing down, but since im going to be using sand will this kick the sand up. my other question is what type of flow rate should i use. thanks in advance for the help.
flow rate and spray bar question

It would take quite a strong return pump in order for the downfacing spraybar to disturb the sand below.I dont know how high your tank is but it's probably at least a foot high and most spraybars are near the waters surface where they can cause ripples and provide better oxygen.
Your spraybar should be positioned within 6 inches of the water's surface (submerged) and pointing towards the surface (at an angle) to help agitate the surface for oxygen transfer.
I have sand in my 29 gallon and a Rena Spraybar on a Fluval 304. The sand will get kicked up slightly just with this setup so on a Eheim P3E I am sure, depending on the depth of the tank and spraybar, sand will get kicked up if its pointing down.
