yeah i think its just a higher ph here ill have to verify tomorrow evening when the new pH meters get hereand your water is excellent, practically like RO/Di
bubbling water only nute solution stays in 1-2 gal buckets with no agitation unless it goes into my res which has a small pump circulating the nute mixture this naturally raises pH some and after pHing maybe 1-2 more times it stays solid... bubbling the water only, or the nute solution?
so i did some digging on canna's website and found that initial runoff can be high due to coco dust and should be rinsed easily hence the ppms dropping so fast. i put about 1.5 gals threw it maybe not much as i would expect from a initial 1250ppm runoff . wheew!.. see how fast it went down after some flushing! -how much did you put through?- a note I read about coco flushing: never just pure water as you know,.. use RO/Di (or low ppm) water, with 150ppm Ca-Mg plus 150ppm nutes, pH 6.0; pour through until pH/ppm's are at or near input values,.. this preserves the CEC, while purging the excess crap,....

yeah my water is really sensitive to ph down when there is little ppm/nutes in it lolremember with RO/Di/low ppm water, there's little to no carbonates in there to buffer, so even small inputs will cause large swings in pH,... I assume it took tiny amounts to adjust it down!
its just a cheapo one brotha. here is the 2 new ones(still cheapo's lol) i got until i can afford a more expensive one. gonna be like 2-4 weeks.uhhh, what brand pH meter? I'm not familiar with some of them, like the cheapo-units-- if this is one of them,... two calibration points is best for good meters, but shouldn't jump back and forth like that, mirroring your adjustments at each point..? Mine hasn't done this, it's a middle level one, so I don't know what to make of it other then it's a design flaw in economy models,...![]()
Amazon product ASIN B005H78ZI0Amazon product ASIN B00N7432IIi figured having 2 will help me be able to make sure my feed pH is correct

and im not sure what you mean by mirroring my adjustments.
As it reads, it implies you're submerging the A8 into liquids..?
