Ph level 7.8

[rmendis]

I would love for you to show me some proof that CO2 build up inside a house will drop the PH in a tank. Is there an experiment that is out there that excludes all other factors that effect PH and narrows the drop in PH to a house full of CO2? If somebody actually did that experiment then I shall concede to your house full of CO2 explanation, but lets be real here. What solid info will this site possibly have about CO2 build up in a house and it's scientific relation to the build up of CO2 in an aquarium.

This has been discussed on many threads here at RC. Simple tests like opening the window or comparing indoor pH tests to outdoor pH tests seem to indicate that certain levels of indoor CO2 can affect a tank's pH level.

Why can't I increase my PH?

I'm not sure what you disagree with, mb4000. Is it that you don't believe CO2 can build up within a tightly sealed domicile, or is it that you don't accept that it can effect PH?
BTW, if you re read my post, I said PEOPLE tend to go outside and get some fresh air, your tank doesn't have that luxury. I never suggested that people leaving and returning added significant fresh air to a home full of CO2. I don't think I've been arguing with myself here.
Do you at least accept that CO2 is a byproduct of animal respiration?

You would have to litteraly never open a window or door and have a ton of people inside the house with no plants of any type to build up that much CO2. With lots of surface agitation and good water movement throughout the tank there will be plenty of oxygen inside the water. Like I said, The tank should be the least of your worries if your house is building up CO2.

My first response was more of a joke since CO2 in the house is a safety issue rather than a PH issue.

My second response was because you actualy believe that somebody would actually build up enough CO2 in their house to effect the PH

My experiment response is because your responses tend to suggest that PH is gonna crash left and right due to high CO2 levels.

It is funny how a humorous resonse could cause such a debate about something that probably will never happen.

taggin'

It doesn't appear that I'm going to change your mind, that's okay.
Should I start having problems maintaining PH in my system, one of the first things I'll do is open a few windows. I'll also recommend that course of action to others that have the same problem. It might not be the solution in every case, or any case for that matter, but it certainly couldn't hurt.
BTW, did you take the time to read over any of the links rmendis posted??

Guys, some people just refuse to accept certain things and itââ"šÂ¬Ã¢"žÂ¢s not worth your time arguing

Mb4000 I would kindly ask that you do some research before you begin to argue, certain things are just conmen sense.

Co2 build up in house

Co2 build up in house

Co2 build up in house will lower the PH in a Tank. Here is the test I did, PH at 7.8, run tubing from outside to Skimmer air intake after 24H PH 8.1. Take tubing off PH back to 7.8 after 24H, Tubing on and Ph at 8.1. This is only when AC is on

Hey Kevin,

WELCOME to R/C!

Here's another article that says inside CO2 levles can cause low pH.

Very interesting.....so high CO2 causes the PH to drop...or lower CO2 causes PH to drop?

 

[DgenR8]

High CO2 will cause PH to drop, significantly in some cases. This tends to be a problem more often in newer houses that are very tightly built.

I have the same issue. CO2 inside the house is keeping my PH low.

I did a couple of tests to confirm (based on the articles from Randy)
1. I took a water sample from the tank (showing 7.85 PH) and aerated with small pump and stone for 2 hours inside the house. PH did not change.

2. I did the same test outside of the house. Resulting PH was 8.2

Was this close enough?
