Serp;3441063; said:can that be toned down to work on a 37g? sounds like it might be overkill, but thats about the same price i was goign to pay for an eheim 2026 w/media.
ever run one of these fx5 with sand? curious if the impeller gets destroyed since its located ont he bottom of the canister.
No reason to bother, dialing it down is just wasting money. Just get something suitable for your 37 like a smaller eheim model.
I run mine with very fine gravel, and just hacked off about 5" or so off of the intake. There's a purge valve at the bottom you can run a hose too and wash out any sand that might get in there. As long as you don't have anything that is kicking up a lot of sand, you should be ok. You can always put something over the intake as well, and just make sure to keep it cleaned off.
