High Temps and O2

[bwid713]

Ok, So at what tank temp do u have to worry about adding some type of extra O2?

I know it varies with surface agitation from filters and such, But would would be considered temp limit before you need an airstone??

What fish do you have? Size of tank? What temperature is your tank currently? Any reason to increase the temperature? Most fish are intolerant of the high temperature actually so you need to be careful in adjusting your temperature.

once you get into the 90s id be sure to have lots of bubbles (bubbles dont add oxygen its surface agitation blahblahblah do some searing if you want to know more)

but at the same time once you start getting that warm most fish are going to start dying or atleast being really really unhappy..

Im more lookin for FYI type information, not spefically for any of my setups,

well use a general example

tropical fish, in a "stocked" tanks not over stocked but "good" stock, in the event of a hot summer with temps rising naturally

Im jsut kinda lookin for a limit so i know when i have to plug the pumps into sumthin besides the back up batterys

Warm water does not hold as much oxygen as cooler water. So warmer tanks should have lots of aeration to sustain the fish.

I know its the surface agitation, the bubbles produced by the air stones are to big to dissolve. But the bubbles of the air stone create surface agitation.

So 90s bad, anyone else say higher or lower???

Yea, i know that, thats y i asked the question, what is considered "warm" to the point of needing extra aeration

or you could just get a chiller so you dont worry about the temp now before you freak and go npo way those things arnt cheap you can make one for around $30 my tank wont go over 82 on the hottest of days even in the sun

There is no "point". There is no certain degree that it changes where you need more. Simply that warm water does not hold as much oxygen as cooler water. When you keep a coldwater fish in warm water, you really really have to add a lot more in. Otherwise the health can be affected in both long and short term.
