Considering C02

Hi,
I am considering using C02 for my plants but I am concerned that it may vary the PH too much. Has anyone any experience or are using a C02 system that can advise please!

I have fish that like alkaline water and at the moment my PH is 8ppm.

Hi Mervyn. CO2 will slightly affect the Ph, but probably not noticeably. I was given a digital pH meter so I can see that with my CO2 having run out, the H has increased from 7.3 to 7.8. But I have fairly soft water and rely somewhat on my CO2 for kh (carbonate hardness). So how much the CO2 will affect the pH of your tank will depend on its kh.
There is a post some where that explains the science of CO2's effect on pH, but I'll have to have a furtle to find it, as I can remember where it is.

Hi Mervyn been running pressurised co2for about 2 months now and it certainly makes a big difference my plants look and grow fantastic  but it's hard work with big water changes 40% once a week. I use a fire extinguisher  which I found was the cheapest option, as for your fish you will find them very adaptable and the ph will not efect them to much

Thanks to both Helen & Skull,
You have given me something to think about. I would have to convince the wife of the expense, but some of my plants,such as my Ludwigia Glandulosa, are not growing as fast as I hoped even being "fed" a complete fert and liquid carbon.

Thanks for that Colin,
I was thinking of one of these? But I have read that the co2 produced can be erratic?. link I certainly would like a reliable method.

That's neat! Did you watch the video?  ??? It must be the worst one I've ever seen - especially the music!

Go pressurised it is a bit more expensive but in the long run once it is set up it so easy it looks after itself,just gone to a inline diffuser which goes into your outlet pipe and the co2comes through the spray bar,it's fantastic and it's one less piece of equipment I have in the tank,all I have in my tank now is a drop checker,spray bar,and 2 power heads ,here's a picture of my tank,

Looking good Skul  ;) Still not decided on co2 yet...it is very costly to set up. I am seriously thinking of DIY setup just for the sake of cost.

I realize that pressurised is far superior but I do not think that I can convince the wife of the outlay.

What worries me about DIY is whether it is going to be safe enough and whether there will be enough co2 for my tank...Rio 180 with about 160L after decor etc. Even the cost of the setup for that  the hardware etc will be hard to convince the wife.

Personally I would opt for regulator/solenoid and fire extinguisher setup. But that is a pipe dream I fear. :(

Yes it is very costly,wife not that happy with what I have spent on my tank recently about £600.00 but it keeps me entertained and keeps her happy that I'm not bugging her so everybody's happy.Diy setup I never favoured it seemed like a lot of hard work plus they can be a little bit erratic from what I have read of them and will it be able to produce enough co2 for a tank of your size.You may have to do some serious reading up on them to see which is the best option.I sourced all my bits for mine on teebay managed to get a secondhand reg with selanoid for £40 and only paid £20 for a 2kg fire extinguisher  think everything cost me about £100 altogether which I thought was quite cheap
