'cos o' da european heatwave my tank temp isup to 29 degrees celcius. is that ok????
if not what can i do???
i did a 25% water change today with cold water and got the temp. down to 27.

29 C is only about 84/85F. That is not that hot - actually not much to be concerned with. WArmer water holds less oxygen, so you should address that problem, however.

You can add extra air features - extra bubble bars or stones. You can place a fan blowing across the surface of the water. You can lower your water level just a bit so a water fall return on the filter splashes and agitates the water surface more. These will all help add more oxygen into the water.

Goldfish can and do live well in a wide range of temperatures. 29 is not even at the top of the scale. With proper oxygenation, your fish will be happy and healthy.

Some people like to freeze a bottle of water and drop it in the tank in the event of REALLY hot weather. (32C and over). You can also pour cooler water into the tank, but it will take a fair amount to lower the temp by more than a degree or two. Do not lower it too fast or dramatically, or you will stress your fish far more than the warmer temps do.

thanks!!!

my only problem is that i cant use an air stone or anything that splashes 'cos it gets on the tank lighht and the instructions say thats bad even though the connectors are supposedly waterproof.

You should be able to get a condensation tray which fits the whole of the tank and sits between the water and the light. This stops any water splashing up.

could i use a clear acryllic sheet??

As long as you can easily move it on and off to get into the tank and leave a few mm around the edge i dont see why not.

thanks!!!

ill see today about getting my hands in some acryllic sheet the right size


if i cant get that could i get a sheet of glass instead?

Not sure about the glass but not as one sheet. Ive seen glass used on top but its been in two sections.

as in layered or side by side??

The glass tops are sold like this:

If you wish to make your own, you should get tempered glass and have the edges ground so they are not sharp. I have found a source of the hinges - McMaster Carr - a mail order catalog in my area. I am sure they are available elsewhere.

I like using 1/4 inch lexan for tops. The lexan holds up without sagging for wide spans of tanks. It gives good support to lighting fixtures, etc. Plexiglass has a bad habit of sagging over time.

I use the glass ones like Daryl has pictured. The good thing about them is that there is a 3rd strip of clear plastic (hard to see in the pic unless you know what you are looking at) at the back. It is great because then you can cut it to fit around your HOB filter if you use one. It will maximize your tank coverage to discourage jumpers.

cool!!!

this is all great, thanks!!!

descovered that if i turn the water pump sideways and slightly above the water line-allmost completely submerged, every so ofted it gets a spurt of air in tiny bubbles that are even too small to cause splashes.

its not much but its something!

anyway, the heat wave is coming to an end so all shall be well.

hi have u tried useing a bubble disk i have one and it causes no splashes at all because the air bubbles are so tiny
