PH swings of 1PH and temp swings of 10-12 degrees wont do any harm as people make out, this happens in the wild in some areas
So, you keep your tank at 28C and your tap runs at 11C
I assume you usually change no more than 50% of your water in one go - that means the tank temperature would drop to 19.5C and immediately start warming up.
That is an 8.5C change in temperature, not a 17C shock as you put it.
That isn't going to cause your fish any harm at all.
but take into consideration that it would more than likely be half that because your only doing a 50% water changeSo, you keep your tank at 28C and your tap runs at 11C

Hi
If you read the post correctly, I said "I would also say that these temps are a result of the water mixing, and that any fish directly in the influx of new water may be subjected to temps a lot lower. My tap water is approx 11 degrees c, so theoretically there could be anything upto a 17 degree shock for my fish."
last time i looked 28 minus 11 is 17

well not instantly, but it happens.PH swings of 1PH and temp swings of 10-12 degrees wont do any harm as people make out, this happens in the wild in some areas
I find it very unlikely that those types of temp swings would happen in a couple of seconds in the wild? But i would be really interested to hear about such areas

Hi Beechey
I use a HMA filter for my Discus tank and my CA/SA tank.
Its plumbed directly into the cold water supply and when I do a water change I run the 1/4" tubing from the filter straight into my tank and slowly run the cold water directly into it.
It takes about a minute a litre for the water to go into the tank and cos it runs so slowly and the tubing is such a small bore, it hardly makes any difference to the temperature, maybe 1 to 2 degrees if that.
Hope that helps.
