The quote above is very misleading. Algae will NEVER cause fish a problem. Plants and algae will produce oxygen as well as use it at night as they feed off the carbon in the CO2 and release the excess O.
Most heavily planted tanks do not have ANY surface turbulence at night even if they are running CO2 24/7 and the mass of plants will consume much more of everything than algae.
Why is my quote misleading? I didn't state that "Algae will NEVER cause fish a problem". Please don't rearrange sentences to suit your needs.
And plants use oxygen at night and release carbon dioxide. They cannot photosynthesise in the dark. When it is dark they rest and do not use CO2.
People that run CO2 all day and all night are wasting the stuff. It's not necessary. Do you eat when you are asleep? I doubt it. And plants don't eat when they are resting either.
To set the record straight it is you that is understanding my sentences incorrectly.
I didn't say that you stated algae will never cause fish a problem. I stated that myself. the quote I said was misleading was the one that says......QUOTE...before and after it. It is above my statement highlighted in a blue box. I know....a little hard for you to notice!!! So I did not rearrange your sentences at all. I clicked on the quote button on your post and it copied your exact words. Then I stated the
fact that algae will NEVER cause the fish problems.
You are indeed correct about plants using CO2 in the day and O at night but you are wrong that plants cannot photosynthesize in the dark. Most plants slow down when it gets dark and some do indeed stop photosynthesizing so it is wrong to state that they all stop!!! Resting does not always mean sleeping.
People that run CO2 are wasting the stuff is a very silly comment as you are now offending many very good plant (and fish) enthusiasts) and it is not a waste for them. There are several reasons that some of us run 24/7:
1. So that the Ph remains reasonably constant instead of dropping a point in the day and rising a point at night.
2. Some plants seem to prefer the water to stay the same parameters (Ph and CO2 ppm) I assume because these are the ones that slow down rather than stop.
3. So that we don't have to use a solenoid which of course is electric and once we are at work a power cut will mean the CO2 doesn't come on at all and we then have wasted our money having a stable system because it is now unstable.
4. Some people use CO2 24/7 because they find that BBA grows when they cut it off at night.
So to say it is a waste is just plain silly. And to answer the last of your statements. Some plants do eat while they are sleeping as I have stated above.
Please read my posts properly before trying to accuse me of something. If I say a quote is misleading then I will use your quote. Not change it from something that is clearly visible 2 posts above.
