Recent rodi threads got me curious and after a bunch of reading got a question about tds creep. At idle, the h2o in the product (clean) due to osmosis will migrate to the waste side of the membrane. Thus the product will have less h2o and higher tds percentage, though the same amount of tds. It...

Is it the ro buddy? Got a pic?

That’s the million dollar question. Don’t think anybody has tracked the real world impact. Don’t know anybody that tests for chlorine post membrane. I nominate @Alexander1312!

Salifert for Alk, cal, Mg, no3, po4 TM hydrometer for salinity (no need for calibration) Hanna for alk backup and po4 ulr clarity

Blue eyes and sharp claws are generally bad news

I’m interested. Will msg you.

Be careful. Hermits might kill snails to take over its shell.

Think @ReyDeFarts made the threaded ones for the BAR table at the September CFM.

Bring down the easyreef evo, it’s got electrolytes!!!

I do

If you don’t mind holes in your wall, why not put the vents and fans in your laundry room behind the tank? Resolves the light bleed issue and potentially noise issue as well.

There’s some spots of Dino on the egg crate in the before pic but is gone in the after. I had to look a few times before I saw it.
