To baffle or not to baffle?

No baffles on my 70gallon sump. The skimmer is at the opposite end to the return which works great but I have to throttle my return pump back to slowdown the incoming water (which is located "mid-sump) in order to avoid microbubbles. To solve this I just run a filter sock that gets changed weekly and no problemo. I don't worry about the level in the sump as its controlled by my autotopoff and controller

No baffles either. I make sure my drain pipe is completely submerged on both ends and let my ato take care of the level. I only run my sumps as refugiums.

Ya, I plan on plumbing my RO in full time for ATO, so level is taken care of there. Just the skimmer bubbles left to think about

Ok, so I am setting up a pool, $2.00 to enter. Pick the date Brad's sump overflows

You're just still bitter about flooding your garage. And driveway. And neighbourhood....-lol

My ATO will be plumbed through a timer, so it will only operate periodically throughout the day....

I thought that was supposed to shorten the life of the membrane??

I haven't heard that, but I've never researched the technique. Not sure how it would, most RO units are plumbed under sink for drinking water, to fill a 5g resevoir...tank application seems to be the same principle??

True dat, but filling a 5g reservoir is different than the half inch change in level in your sump IMO. Then again maybe it just keeps the 5g full and it doesn't completely empty. I dunno, I just heard someone on here talking about it, maybe they'll see this and chime in.

Running small volumes through your unit is hard on the DI resin due to TDS creep. When the unit is shut off the solids will cross the membrane as time goes by and when the unit is turned on this large concentration gets taken out by the DI. I now with my online monitor it will read about 25ppm at the membrane outflow upon startup and then settle to about 2 after a minute or so. I don't know what small volumes does to the membranes tho.
