A FIFTH PILLAR APPEARS.

It's just pulled out because of all the chaeto that was stuck in it. Plus I got there first so I picked the biggest ones

It has a root type structure I think.

My money is not on.... clint.

So my hypnea had some chaeto mixed in to it, which i pulled out. I ended up with a pretty hefty chunk of hypnea/chaeto. I could be convinced to part with it if anyone has interest.

little birdies can't be trusted. now big bird, that's a bird you can trust.

The 4 pillars of hypnea have been established.

I got two. I wonder who hopped in and got the third or four.

I HEARD TY AND BIGE VANISHED FROM THE EARTH. NEVER TO BE SEEN AGAIN.

It's in folks. Not many pieces though, I'd call ahead before you make a drive.

man. yo. don't even brah. Whatev. Meh.

man. yo. don't even brah.

dude. bro.

If i want them can i battle esacjack?

burning them in effigy i hope

reef crest should be reefcrest. no space?

That's not a sea cucumber in your pico. its cat poop.

seems that the reasoning would be the same regardless of low vs. super low? does DI resin dissolve? if so, lower pressure = extra contact time = extra consumption. i wonder how much of it is marketing the pumps. @65 psi you get 500 gallons. at 30 psi you get 499.99 gallons. ergo, bump your pump and get longer life...just not noticeably longer. (note values just made up for illustrative purposes. could be off by orders of magnitude) I think that the intended purpose of a booster pump is to get a low pressure system to a normal range system, and not from normal to high pressure. I think you're totally right about the marketing proposition there. I remember reading somewhere that those systems incorporate additional processes to keep the membrane flushed, and to automatically dump the first few gallons of RO prior to it hitting the resin. I think it was in PMRogers build thread. Either way, i think there's more to it than keeping the system running at high pressure.

The membranes GPD rating is measured at 65 psi and 25 C (77, f) so i would assume that it is in that neighborhood.

huh, really. I wonder what the reduction in consumption is. Now if your pressure is super low and you use a booster to get it to where it needs to be i can reason that out. But if your pressure is in normal range and you go higher than that, i can't work out how that would reduce consumption.

it'd probably be a bit much IMO.

If you mean effeciency in terms of time, i *think* that colder water would reduce the pore size of the RO membrane and reduce your output rate in addition to reducing the pure/waste ratio. I don't think it should affect resin consumption, because the water coming out of the RO should be of the same quality, it just gets there slower. As for pressure, i believe that higher pressure is better (i.e., it pushes water through the membrane faster), but that you get a diminishing return after what you would expect your max household water pressure to be (something like 80 psi is where the charts start to drop off). You have other things that will fail on your unit (fittings) before you can go too terribly high, and you don't gain anything from doing so.

Superb condition.
