Re: Water Change Temp Swings
Fry are extremely sensitive to temperature changes. I'm talking 1 - 2 degrees here. 84 -> 72 will stress out even large discus. In contrast, adding prime directly to the tank is fine.
Good luck, Willie
Re: Water Change Temp Swings
I’m not experienced w fry, but a 12 degree swing is way too much no matter the size. I maintain an aging garbage can w a pump / hose, aeration and heat. My garbage can temp is always kept one degree warmer than the tanks it refills. You may have to get a bigger heater or insulate as you said, but do try to fix this large difference in temps.
Re: Water Change Temp Swings
Ok, I guess I need to up my heater game. My temps have dropped 4-5 degrees for some of my water changes and they do seemed stressed after those water changes. I read this thread and the comments from John had me thinking maybe it wasn't a big deal :http://forum.simplydiscus.com/showth...s-water-change
Maybe thats for adult discus though. They are just now active after this mornings water change.
Re: Water Change Temp Swings
I normally keep my aged water at the same temp as the water in my tanks, a few degrees below has not caused any issues for my discus, both the adults and the juvies.
Re: Water Change Temp Swings
I'm afraid that I'll never commit to adding dechlor after the water change because the fish during the change will be exposed to chlorine,etc...while the tank is refilling....I treat the tub/barrel before the fact..I wipe my tub(s) down with peroxide periodically anyway...
..as for temps, wrapping your tub/barrel with insulation or a hot water tank jacket, helps a bunch ...
Re: Water Change Temp Swings
I have too stressed about this and now that I have week old fry. I purchased a few temp controlers. I also now use Celsius. Why cause it's good to 1 degree and Celsius setting have given a why less swing.. now what I do a water change it near perfect!
