Hmm. All i know is that’s what he measured when I asked… He was a fan of not dosing much so I believed him

But according to these charts I should not have low ph and yet here I am, with significantly lower pH than the tables say i should have

Bht at the same time, my co2 is 12-1500ppm in my room, and thus I have cognitive impairment, so there’s a chance i’m misremembering entirely.

That’s really high and not good for you

What's your alk? Still at 10 or so?

I have quite literally noticed improvements in my cognitive function since I've started opening windows. So. I've been nerfing myself this whole time unknowingly :oops:

I kept the window closed because it was too hot out lol

Do you think i can recover my lost brain cells?

Let's hope If you're lucky you might be able to grab a brain coral at the swap.

You must have a very well insulated room. To have this as a issue.

Co2 can get pretty high pretty easily, especially if you have a family and pets and so on. It’s pretty much the main cause for low PH (literally one of two inputs - the other being alk) in most tanks.

People act like PH is such a mystery but it’s really not. It’s why often the best advice is just to open a window.

Now if you have a big family and can’t open any windows…you’ve got a more challenging problem I suppose.

I saw something about running a hose from skimer air intank to outside. Is there any merit to that aproach?

Only something i heard mention of on a few vidoes - no first hand experience with it at all.

It can work if you can't get fresh air into the room otherwise (I have done it - see my tank journal).

The problem is you need a strong skimmer AND you need to minimize surface agitation and flow elsewhere - which will work against what the skimmer is doing. I think this is often overlooked with this solution (and is also a problem with CO2 scrubbers).

The skimmer is trying to equalize your water with the outside CO2 level while ALL the other flow/agitation in your tank and sump are working to equalize your water with the inside CO2 level. And in my case, once I cranked up the flow - I stopped seeing the good effect from the skimmer since all of the other flow was simply working harder to push the room's CO2 into the tank. I think outside lines and CO2 scrubbers can be very effective in small tanks - but really drop off for big tanks that have a lot of surface agitation and sump baffles.

Monitoring the CO2 in the room and trying to keep fresh air going is 99% of the PH battle for me. The other 1% is alk which doesn't really change.

Got it, so not really useful in @tribbitt case with a nano tank and possibly only a nano skimmer. Not to mention all the other factors you mentioned that need consideration as well.
 
"ERV stands for Energy Recovery Ventilator, and is regularly referred to as an air exchanger and an ERV ventilation system. They are designed to be connected into the HVAC system in your home, office, or any other building. They pull fresh, clean air into the building and take out stale/unclean air."

I just have a small Panasonic one which is equivalent to having an open window. It looks just like a vent fan but just functions differently.
