Varied Ph result

[Anonymous]

can you take some water out and airate it for a while and see if the ph raises after about an hour. this should show weither or not it is caused by disolved co2.

Amazing.

They have low ph and nitrates. Plant life fixes both. It's really that simple. Even Dr. Holmes Farley agreed with me in a pm. Plant life will "suck up" the carbon dioxide so that in a 24 hour period the tank becomes a net consumer of carbon dioxide and producer of oxygen. Removing carbon dioxide and adding oxygen to the air surrounding the tank.

What happens at night though when plant life reverses its method, and produces CO2 instead of O2?

Check first page of this thread, already answered that question and even gave the chemistry equation to prove it. Seems to have passed unnoticed by some I presume.

Hi Angy, which post are you referring to? So far, it looks like we're back on track.

SB, that was my point. Plant life can't fix everything, and a low PH/high CO2 problem would be "temporarily" fixed during the daytime. With lights off, and the opposite of photosynthesis occuring, then I believe the problem would only exacerbate itself.

On top of what Mark asked, please also include the following :

- Filtration if any
- Powerheads if any, number, gph for each, placement in tank
- Sump if any
- Size of tank including dimensions
- Lighting
- Substrate
- Live Rocks, amount.
- Water parms : Ammo, Nitrites, Nitrates, pH (daytime), Alkalinity, Salinity or Specific Gravity, Calcium, Phosphate.
- Fish population
- Corals / inverts if any

Do you even have an idea as to why I am asking the question I did?

Oh just shut it, will you!!! I asked those questions to complement your set of unprecised questions. Gawd, do I have to spell EVERYTHING for you to understand? We need all the details we can have. That's why I posted those questions after your post...as a complement. Geee... get a grip man!

No you did not. I wanted to see if he was dosing anything that would effect the pH. Wanted to check to see if the tank was being airated properly, etc. If you have a problem with me please take it off line.

Hey Mark and Bob, if you guys have issues with one another, please simply ignore one another.

100% agreed

Yes I did and please just shut it. You are only seeking an argument for no reason. You've been doing that to me in several threads. I posted my questions to complement yours. If you would use your brain for one second, you would see that we are seeking the same thing : A better, complete picture of the problematic tank so we can better solve the problem. I have no issue against you, but get off my back... is that clear enough for you?

Now back on topic!

Bob, I will give you no further warning. Your continued insults and your non-compliance with my last warning in this thread will not be tolerated. I can understand some of your frustrations, but the way in which you worded your opinion was downright uncivil and rarely leads to an understanding of two conflicted parties.

If someone rubs you the wrong way, be the better man and ignore it instead of escalating the situation. This goes for everyone, not just SB.

Yes plants do consume oxygen and release carbon dioxide during lights off.

That is the reason I specified the 24hr period. It is better to have a ph that rises to 8.4 and higher during the day and drops to 7.9 or so at night then have a constant ph of 7.8. Because that means that insufficient carbon dioxide is being removed from the system. The permanent fix is to change that situation with additional plant life.

Whatever else is known, plant life definately consumes carbon dioxide and nitrates. Which is the problem in this thread.

I stand corrected Guy, Thanks for sharing the reference about CO2 in the home

[/quote]You bunch of americans are so thin skinned and are sooooooo easily offended that it's not even funny. [/quote]

This is a deal breaker for me.

A buffer is not going to raise or lower your pH for any extended period of time. A buffer will only help the water resist to changes in pH. I dont think a pH of 7.9 is to low and no need to yell fire. How are the animals in the tank doing of the Original poster?

Sponge BOB: I dont think that posting chemical equations is going to help the OP.

can you take some water out and airate it for a while and see if the ph raises after about an hour. this should show weither or not it is caused by disolved co2.

I don't remember if this was suggested earlier but it is an excellent suggestion.

I might take heat for this but if it doesn't change after an hour try taking some water outside to aerate it to see if there's any difference in PH.

My pleasure Nautilus.

To be honest have read all this but have refrained from posting fely like a nuf nuf!

Having said that will increase gas/ surface transfer and open doors and windows while it makes sense to do so(in other words until my wife is cold :wink: ) and will see if over the next few days if the ph lifts

Thank you to those who helped without the barb wire attached appreciate it

Regards Darren

moving a power head near the top of the tank to disturb the surface of the water will help out with gas exchange as it increases surface area as well as moving fresh water to the surface for exchange.

 

[Anonymous]

How is it going for the original poster? Any changes?

fwiw, guy helped me out a lot in the past. He did spark me to learn a lot on my own about pH-alk-calc and the relationships between them.

Buffer does NOT raise pH, except only temporarily. It is a mask over a real problem. The only thing adding excessive buffers will do is raise the alk and throw ionic balance all out of whack.

I didint see it mentioned, but better surface agitation will help a lot of the time as well.

 

[dearis]

The only surface agitation i can provide to this tank is an air pump near the surface to try and reduce co2 hoping it will help and hoping the bubbles wont be too bad in the tank.

Regards Darren

P.S. Ph is 7.9-8.0 flickering between the two

 

[ChrisRD]

That is the reason I specified the 24hr period. It is better to have a ph that rises to 8.4 and higher during the day and drops to 7.9 or so at night then have a constant ph of 7.8.

Actually, it's probably worse, but neither scenario is recommended. A pH swing of 7.9 to 8.4 in a single day is a lot and likely a sign of poor aeration. The better aerated the system is the less pH swing you will see from normal day/night effect.
