Going after low pH

And then again at the end of the photo-period when pH will be the highest.

 

I understand the theory. It's what I've always assumed. Makes sense. However, I started yesterday morning before lights about every 4 hours until 5am. All tested at 7.7. I may get a new kit just for second opinion. Kit is not expired

 

Try the increase in O2 and see if that works. Do you have a sump? Can you do a reverse lighting fuge or ATS?

If able, and when convenient I would try and eventually test via a different method.

I would not have so many dang test kits if I was confident in any one method other than my Hanna Alk.

 

I particularly don't trust them when something is way different than I'd expect.

 

If you can't easily run a line outside ..A co2 scrubber is super easy. I bought a 5 gallon bucket of soda lime that will last a couple years or more. Just duct tape skimmer line to a bottle, poke some holes and done.
I use a brs reactor insert. Took about 60 seconds to set up.
PH went up about .3

 

Now this I'd like to learn more about. Thanks for the tip. I'll look into it. So far, I'm not seeing an improvement. pH still is hovering around 7.7.

 

So I looked up the CO2 scrubber. Looks very simple to set up and low tech to maintain. Great tip AV8. I'm putting that on the plan B list. Looks like it's about guaranteed to raise pH by .3. I'm going to try bringing in outside air first and go from there. Ideally I'm shooting for 8.2+. Since I'm starting at 7.7, I may end up using the scrubber. My thinking is that the outside air method would be less maintenance. May offer another layer of stability too.

 

Any tips on drilling a hole from the outside through stucco? Mostly concerned about electrical. Hole will be 3/4".

 

If you are able to run it near a window, there is a very slim chance of hitting anything electrical. Windows should have a 2x4 surrounding and a header above which is 2x6 or more and sometimes there is a gap filled with foam insulation between the window and frame. There shouldn't be any electrical in that area but you can buy a ,current detector, name may not be accurate, at lowes/HD for pretty cheap. I got one that came with a multimeter. Basically chimes when it comes near any electrical lines.

 

I'll head down there and get one MD. Thanks
