sump turnover rate

  • We are currently upgrading MFK. thanks! -neo
Uh, one thing to keep in mind: your wet/dry works MUCH MUCH MUCH better when the media is exposed to air. That's the "dry" part of a "wet/dry", and that's why they are also called drip systems.

After a certain point, increased water flow keeps the media constantly covered in water and dramatically DECREASES FILTER EFFICIENCY.

From a filter perspective, turnover rates need to be high enough to keep ammonia/nitrite at 0. That's it. No more is needed. As Rallysman mentioned, 3x can be plenty good enough.

If you are worried about water movement in the tank to avoid any dead spots, you can use a power head. If you want more oxygen, then you can use an air stone. But let the filter get plenty of air directly on the media by avoiding a constant waterfall of water.

BTW, I suspect 10x beliefs originated with HOBs. My HOBs tend to slow down over time as the media clogs a bit. 10x easily drops to 5x or less, so it makes sense to get a filter that can move more water when it's shiny and new.

The 10x turnover rate mantra should never be applied to a wet/dry since the flow should really depend on how much water can move through the drip plate and still let the media get air directly.

Just my experience...

.... I wonder what it would be like to use a diatom filter from a 20,000g swimming pool, with a couple resin filters for ammonia. Getting close to nervona? (not the band)

Hey, if we filter to much could we end up with just Oxygen & Hydrogen?! ;-)

hmmmmm ... now that's a thought ...
perhaps a distiller with a condenser would fit the bill. then we would just need to add trace ellements for the perfect balance..

I think it's time to win the lottery

PS. is anyone else not able to see the smileys today?

It will be fixed soon, Li is playing with upgrades again:)

We have to keep MFK FAST you know! lol

Bigger sump...problem solved.

Funny, I was thinking of that again today...I was trying to figure out how to distill without great amounts of energy useage or pollution.

Do you understand over-unity theory? ;-)

Perhaps a home-made 'still' ... An evap chamber & a condenser. I have made them before but never for that volume. I would think a turnover rate of 1 time per day would be fine though.

I made one that would make about 50 oz of pure water a day from raw ocean water with just the SUN. I will have to think of what it would take for like 100 g/day.. If we could get a rate of 50% per week, this would be an interesting way to remove nitrogen & loosing the waterchanges...

We just need to get the 'heavy waste' out somehow.
Also cleaning the evaporation chamber might be an issue.

Sometimes called a perpetual generator; I played with the theory in the 80's. Never attempted a prototype though. We often joke about just plugging a power strip into itself ...lol...

Didn't mean to hyjack this thread...but..
Glad we started this conversation, it reminded me of a solar project that may work... I'll keep you posted

Yep, I played with it too... Best I got was in the nano-amp range, maybe it will be useful in another 20 years ;-)

Hope that was the very late eighties ;-) (I did't get into quantum physics untill I was 14, freaked teachers out... they didn't know if I was right or wrong)

Nah, power strip won't work...tried it... But a UPS on the otherhand (think about it).

Fun ain't it?!

Here is a pic of a perfect one...We just need to get the nice folks in Lynchville, Tn (pop. 361) to let us use it.

Yep, I have been having smiley withdrawals lately

I think we all tried some sort of perpetual motion device. As a kid I designed a ramjet, but my mom said it would never work...
