Curious how that would work with the back flush the RO's do. Would it run some of the calcium out of the waste line? Or would it be installed as a standalone post filter or something. Interesting idea, let us know how it goes.
Typically tap water that has high carbonate hardness (aka dKH) is water that has CaCO3 and MgCO3 (calcium carbonate and magnesium carbonate, respectively) in it already. Why strip it to then add it back? Instead of going to all that trouble, if you want CaCO3/MgCO3 back, add a little tap water back to the RO water.
There is also a problem with CaCO3/MgCO3 in that they don't seem to be readily available for uptake by the plant, at least not as I've found by my own efforts. I believe that the form of Ca/Mg is very important, and if it's a form that can't be taken up by the plants then it needs to be mineralized by microbes. This is why I can use unfiltered tap (well) water that has not only a very high level of carbonates, but also general hardness, on my OD organic girls, yet cannot on my indoor coco girls--well mineralized soil with a healthy soil food web in situ vs non-mineralized coco sans healthy soil food web.
I know I spelled discussion wrong. Sorry about that. I noticed it the second I did the OP but I couldn't change it once it was posted. My apologies once again. Fortunately you were able to make out the meaning of the misspelled word so I suppose the title wasn't all that misleading to ya.this is a very good iscussion
can i join in on this iscussion?
i think seamaiden is right on with this iscussion
the calcium really needs nitrogen to assist in the untake of the calcium, and you will find none of that in your iscussion
i think fat man has a good iscussion about it
a very good iscussion
Ya the tap water is definitely a decent Idea, but I would rather have the chlorine, and chloramines removed inline without having to let the water sit out for 24 hours. But if One is willing to wait it is a good idea no doubt.I like r/o water...then adding calmag.....but......Seamaiden has a good idea of using a bit of tap water.....i have a buddy who uses 25% tap water along with r/o....He just lets the chloramines and such evaporate off the night before he uses it.....He doesn't use calmag, which saves him some dough......He gets great yields and quality.......Peace
Chloramines don't dissipate? Huh.....Cool.....Thanx for the info....Calcite cartridge huh? Where did you hear about that? Sounds really cool and it would be nice to stop paying for all the Calmag
Chlorine (sometimes referred to as free chlorine) is being displaced by chloramine, which is much more stable and does not dissipate from the water before it reaches consumers.
