no idea what sort of a stand a cheank stand is, but it doesn't sound like you did too bad.
the only thing that really matters is if you're happy with it.
Sumps can be loud depending on how you run your drains and how high the standpipes are in the overflows.i thought it was a good price with the 90 gallon sump and hammerhead water pump myself.........one more question if anybody has a sump pump i wam going to re route the plumping to put it under my tank stank withe the hammerhead water pump...my question is are sumps or water pump loud in anyway? i can take a vibration butis it any worse then that? thank guys
