Who said anything about too much oxygen being harmful? Tim clearly said how it's important to make sure there is "sufficient" oxygen in the tank; he didn't say anything about making sure there isn't too much. And by the way, having a HOB filter, air curtain and plant isn't going to saturate your tank with oxygen; all it's going to do is keep the dissolved oxygen in the tank in equilibrium with the air around it.

it will remove a lot of CO2 which could be detrimental a large plant load.

Well never said anyone said it, just curious if you could have to much..

What will remove CO2? If you're referring to aerating the tank, then yes and no. Aerating will remove CO2 IF CO2 is being dosed into the tank, OR if there's enough fish that the CO2 produced is higher than the equilibrium concentration. However, if neither of those are the case, then aerating will replenish the CO2 that's being used by the plants.

Sorry, I guess it just sounded very sarcastic. No, you can't have too much O2 in the tank. And it would be very difficult to oversaturate the water with oxygen the way a typical fish tank is set up.

I also find it amusing that the number one most important measurement one can make for fish is for dissolved oxygen, yet hardly anyone mentions this and likely most do not have a meter. How do you tell that your fish are in an oxygen sufficient environment? By their happy behavior, or are they just coping with the environment you are subjecting them to?

BTW, presently I am doing 8% avg daily water changes and checking all parameters [including O2], as I have a young tank with young discus but I am working towards very minimal water changes, once I acheive a measurable balance. My municipality uses no chemicals and I heat the water in a tub.
i agree totally bleach water then de-bleach it then put in copper piping x years old then add it to our tank how many minerals and good things for fish can possibly be good for them to breath and we have to do lots of water changes so our plants thrive and out fish yet we have all seen people who do yearly changes and all have thriving fish long as they clean it out monthly

but no science talk but most scientist have one aim not many like the best

And all my water test kits read under 10ppm for the other tanks constantly anyways so obviously no, not true. My fish would start dying before we even hit 40ppm since they are fragile species.

i must be doing something wrong then because i have an overstocked 350L that only has 20 liter changed monthly or bi monthly depending on how long it takes my DIY 2 liter 600lph filter to choke up

i only vacuum 6 times a year at best and all my test always read 0 except nitrate that is constant at 0-5ppm on test but from color it i abouts 2

lol :P

Rephrase: it will remove a lot of EXCESS CO2 which could be detrimental to a large plant load, particularly if you are adding CO2 to the system.

I expect that it will still lower the dissolved CO2 to lower levels than might be occurring naturally which may not be noticed on small plant loads. I still think that it could affect, however slightly, larger plant loads even if we are not adding CO2 artificially.

Plants will only grow to the potential allowed them based on the lowest nutrient that is available to them.

too much air achievable if the water conditions will absorb enough yes i cant say it is bad or unhealthy to a fish but i can say that most of the habitats are not mega high in aeration like our tanks

but it is also apparent that aerated water helps rid of nitrite quicker

a hell of a lot of tanks are more aerated than there fish's habitat but we do know that a bit more is always healthy

And the article on stress sets out some of the issues that occur from inadequate management.

I'll just make a quick comment on the matter of things being fine without...you can't possibly substantiate this with fact. What may seem fine now, is not fine. And while some fish do seem capable of existing under such conditions, others cannot and will not.

Byron.
so what about my clown's and glass cats and the fact that before i rid of my apple snails they had bred many time's this would not happen in a unhealthy setup

glass cat would be the first to go if there was anything wrong
