Hi guys so what ppm do i need for my tap water? Right now it tested at 48ppm without ro filter. With ro filter it drop down to 3ppm. I'm just wondering can i just use the tap, because it takes too long to fill up 120 gallon with my ro filter.
Yo red! With a ppm out of your tap like that your good no need for ro, just of course let it sit out for 24 hours before using it
Which I see would be a pain in the ass with 120gs. You might just need to invest in a dechlorinater. I doubt spelled correctly!
can i use airpump to evaporate chlorine? Also i have a hydro logic tall boy prefilter. Well that work for chlorine..?
was gonna suggest the air pump. will only help evaporate faster. but with 120 gallons gonna need a big airstone the prefilter though, i have no idea
Most folks would kill for tap water with that low of ppm, mine is 10 ppm higher then yours and has been fine, I just let it sit for a day, just remember to deduct the tap ppm number from your overall reading.
Right, I was also impressed, our tap water is obtained from the ozarks, (where I live), it's 32 ppm and 6.6 out the tap! And I haven't been doing that Mr.Florista. so if I'm at 250, then I'm really only at @220, curious!
I do concur, I'm certain you would want to add that as well, being that it is trace mineral and elements. The plant does take those up.
You deduct the water PPM from the overall number to track the nutrient ppm's you've added. The water PPM is an unknown, thus it should not be added to the nutrient count.
so, regardless of whether or not my plants react negatively, if my ppm is 142 i should completely ignore that number? you're new here so trying to give you the benefit of the doubt but seems like a lot of misinformation is already coming from you
How much nitrogen and/or potassium is in your tap water? Unless you have it tested you don't know, correct? When you feed, do follow the label feeding schedule? I don't! I always reduce by as much as 2/3 from the beginning of the grow and add by observing the plants.
Anything that's in the water, you are feeding your plants. And (food) in the water is registered as an ion with a positive charge equalling @1, thus, our meters pick up said charges and calculated according to temp. Any particle whatsoever is registered and should be considered food for the plant. Including the food out of your tap.. If the water reads 250 in the rez, then you have 250 particulates of matter total (food). Including the trace minerals and elements in your tap water. What if all the sediment out of the tap is calcium? would you still provide your calcium supplement or trust it's getting it from the other 50 ppm in your original water
If you are having negative reaction from the water alone, I would get it tested, how much waste chemicals are in your water? They have ppm's correct? There would not be enough nitrogen etc. to cause "negative" reaction.
