Dedon started grow question 3 years ago
Hi everyone !
i have some trouble with pH stability, i washed my tank with bleach when i change the water, but since pH increase from 5.5 to 6.3 in almost 6 hours. i also use peroxyde hydrogen.
do you know if h2o2 can do that or is it because i used bleach :/
Thanks for your help:grinning:

Perhaps, although it might not be due that. Keep in mind that as plants aborb more water (or more nutes) the pH balance of you reservoir will change as the concentration of nutrients dissolved in the water changes, pH instability can be a sign of a reservoir too small for your need, since a small water (or nutrient) uptake drastically changes the concentration of the solution. good hydroponic nutrients are buffered to prevent this. What you can try is to buffer the solution yourself by adding more pH DOWN AND pH UP, to force (buffer) the solution to stay stable at the desired range.

I wouldn’t recommend using bleach or peroxide unless after a grow. If you’re cleaning the tank between grows, spray it with hot water and wipe it dry with microfiber - Which can actually pick up bacteria. During your grow, just add positive bacteria or enzymes. You can try Hydroguard, Hygrozyme, Voodoo juice, Sensizyme... add something like that. Unless you’re doing a periodic, post-harvest clean - peroxide is probably overboard IMO. Also, like Athos mentioned, you should expect to see pH drift with nutrient use. It will happen mostly during first few days of nutrient change, and gets steadier over time. Ions, both positive and negative, are being removed from the solution. Just keep your eye on it, calibrate your pH pen every 2-3 weeks max, and you’ll be good. Let us know if anything else pops up!
