What's your GPH water turn over rate on your tanks?

  • We are currently upgrading MFK. thanks! -neo
The more efficiant a filter system is the less need there is for massive turn over rates. Contact time is VERY importiant in the most critical stage of filtration...biological...

Put a bit more simply... the amount of times you run water through your filter is far less importiant in the long run than the amount of debris and contaminates removed from the water on each pass...

The target turn-over rate for any given volumme depends almost exclusivly on the TYPE of filter system your using...

HOB units require the highest rate...with canisters secound...and properly set up wet-dry systems next followed by sealed pressure systems.

The pump ratings on wet dry systems rarely ever reflect the actual GPH of the system as a whole.
 
150G-1850GPH with 2 Emp 400s, 2 XP3s, and a Mag 350.....~12X per hour
100G-1300GPH with an XP3, AC110, Penguin 350, HOT Mag...~13X per hour
75G-750GPH with a XP3 and Emp 400...~10X per hour
45G-500GPH with a Penguin 350, and Penguin 150...~11X per hour

My other tanks are filtered mainly by UGFs, and internal box filters and sponge filters so Im not going to bother listing them :)
 
around 10x on all tanks
 
on my wet/dry filters it's about 2.5-4x per hour. I don't know about the others.


I love the low flow on a wet/dry. My 265 has a decent stock, but 2.5 turns is plenty (and nicer on the wallet).
 
I'm going to run a Mag Drive 2400 on my wet/dry and a Mag Drive 3600 on my two Ocean Clears and UV. That's a total pump rating of 6000 GPH but I know darned well I will be lucky to see 3000 tops due to head loss, piping loss and especially loss thru the OCs.

I bought a couple of high rate flow meters so it will be interesting to see what my actuals are. I hope to have water flowing by the end of the month and will post my results.
