That’s definitey work!

My work is mentally exhausting and tonight I’m fried from a rough day - and knowing what kind of week is ahead of me. I think I need a drink!
Honestly physical work you pace yourself at, but retards that make the job harder than it is, is my pet peave. I would rather bust ass from the first cup of coffee, till the last hr, where I utilize my special training and push a broom around my area... lol...

No hvac. I work in manufacturing. Our flagship equipment has been used around the world as well as by all branches of the military since at least WW2. Im not gonna say where, but its equivalent to Komatsu.. We actually built out a set of flood gates for New Orleans after Hurricane Katrina...
I’ve used hand held cutters for scribing, pretty cool :).

cj how long did you let your nutrient mix sit and settle before you tried adjusting the PH?
Nafy, has a point.
Mix your nutes and let the mix aeriate for 12 to 24 hrs prior to pH adjustment. Let it stabilize and your problem should be solved.
When my rez gets low, about every 3rd day, I make my new mix and let it stabilize for 12 hrs prior to adjusting the pH, this has worked well for me.

I’ve never had an issue with mixing the whole amount when I change out res but I always dump and fill. Mind you it took a bit to dial in the amounts to add, and lots of note taking lol. I just fill half way with water, turn on pump, and add nutes, then ph, I do check the next day just to confirm all is kosher and re check periodically through out the period before changing again. I did stop using air stones as I did find my ph fluctuated more.

what do you use instead of air stones? you just on recirculating?

Flood and drain/recirc depending on pump cycle. Basically flooming though with water fountain type action
So basically a passive diffusion!
Amazing how well it works. My GF is a waterfall freak, I like them also, but she wants to build a falls system for passive diffusion, she got the idea from a small fountain on my patio. It could work. So will be looking how I can do it later this spring.

Edit: cut from mommy I mean lol.
