Does a KDF carbon hose filter rob cal-mag from tap water?

Got this filter to flush the chlorine and chloramine from my tap for gardening. I guess noticing that it removes heavy metals made me think maybe it also reduces magnesium.
Wondering if there’s anyone with direct experience. Maybe i should add more calmag to compensate.

Ive wondered about these filters leeching minerals out if the water so i was hesitant to get one was having calmag issues at the time.I opted to get an ozone generator that also treated water to bust up that New chlorinamine shit, its bonded right to the water molecule and you have to break it off.I wondered how does that filter break it off the bond?

@Pigeonman uses one of those filters like the ones for RV water i wonder what he could chime in?

I gotta say if it works, it beats maintaining 2 trash cans full of water. Tho post filter it still smells of chlorine, at least more than when i off gass for a few days.

Although I have not noticed any difference whether or not I remove the chloramine, either way the plants and microbes grow fine, I do have and use a chloramine filter. The nutrient mixture should be providing all the micronutrients a plant needs, so I don’t particularly want unknown quantities of whatever the filter is removing in my feed solution

Yes, but even a standard carbon filter will remove a fair amount of calcium. Personally I like removing as much mineral from the water as possible. It allows me to put back the amount of whatever minerals I want in there, not having to guess where I started and try not to over-do or under-do on adding my minerals to the water. And yes, more cal-mag is the answer. Well, technically you could just add the calcium back in, but then your ratio of calcium to magnesium would be off.

I have a run of plants going right now as an experiment i watered with plain tap water as is.Got to say so far im not seeing a real bad difference here.It will all boil down to how she smokes but im not seeing anything bad yet.Have a look

Ok good information. Sounds like you guys are not fans of hard water. Im all organic so ill add a topdress of micronized calmag weekly. Probably cant hurt either way.

So all organic…no attempt at chlorine removal? Those look beautiful.(dialed in)

Just TPS one and the Bud and bloom booster with General Hydroponics Floralicious and un treated tap water thats it.I dont even PH it.All i did was one weekly feed with regular unfiltered untreated Buffalo Ny tap water .Normally i use a 55 gallon reservoir i keep a huge air stone in to keep my water oxygenated and fresh that i run my generator on for 12 hours to treat the chorine and the chlorinamine.This one run i never ozoned or filtered anything.I add the TPS after my organic soil mix is depleted.i time it twords when i flip so i dont have to topdress and wait two weeks for the feed to uptake

Well the results speak well for your methods. I guess microbes are gonna microbe…but i happen to live just downstream from the local water treatment plant. So i get blasted with fresh chlorine when they treat. It smells way strong. Idk if id be as ok as you. Fellow ny native btw. Now expatriated to the dirty south

TPS one can be used for flower and veg all you do is adjust the dosage probably how my scheme worked out so well and probably the reason i dont have to flush as much.Im not running Salts the whole cycle its broken up tword the end with a weekly moderate dose and not a minimum every watering dosage.Not a whole organic run but a hybrid one i like to imagine.Results are no nutrient stress and less effort to have to flush residual salts from pots saving some work and no adding top dress and wait on potential plant pickiness.

I noticed alot of people run a srt of synth-ganic approach. Im really trying to embrace this living soil thing till i can get it dialed in. My main experience has been with hydro and rdwc.

Do what works for you is my motto.I was never against Salts or Organics and have run both.It is nice when all you have to do is add water

Thanks for the tag @CapnCannabis !

@BudLarfy I use a Smallboy chlorashield filter that does the same thing:

The tap filters are great as they remove heavy metals such as lead, mercury, and arsenic in addition to the chlorine and chloramines.

Personally I always add cal/mag with every solution mix I make when using my filtered water for indoor plants.

For outdoors I use rainwater, but still add the cal-mag out of habit though it’s prob not necessary. I haven’t gotten a tap version for outdoors because I have not turned on my outdoors tap in over 2 years due to my OCD’d rainwater collection and storage system(s).

I don’t add cal-mag when just using water from my filters; but again that’s not a feeding solution.

@JohnnyPotseed uses the hose version and may be able to chime in on if he’s adding much cal-mag to his filtered water.

Hope this helps if at all!

We use the Boogie Blue Plus from Amazon. It takes out a LOT of bad stuff. I always add my Calcium, Nitrogen, etc to my water to feed the plants.
goes on the end of garden hose and filters (no waste!) 45,000gal life
