Yeah, it's normal, especially with cold water. Cold water holds more dissolved gas than warm water, the same with pressurized vs unpressurized. The dissolved gasses bubble out as the water warms up. You can avoid this by heating the water in advance and having it stand for 24 hours in advance. It's perfectly normal with a new tank that was filled with cold water to do this as it warms up. You can wipe them off the glass and shake the plants to get them off if they bother you, otherwise they will eventually disappear on their own.

Putting cold water into a tank with fish can allow the fish to intake the dissolved gasses and then have them bubble up inside their body. This can kill fish just like it can kill skin divers, it's basically the same as getting the bends. I think it's called gas bubble disease and you can find pictures of fish on the net experiencing it.

Do you really mean 10cm?

opps i mean 1 cm watched the tank for a bit and seems the bubbles are coming from the filter should i turn it down as it is making alot of water movement but was told u have to have the surface water rippling

 

[ZoddyZod]

what filter do you have? Are you using the venturi function (if it has one)?

1cm is still mighty big for air bubbles. Sure you don't mean 1mm?

You do indeed need plenty of water movement. That is how oxygen migrates into the water. With a still water surface you'll soon have gasping fish.

yeh i cm i the size the filter is a rena filstar 13-14 in a 84l tank

that's one like THIS then?

If it's creating too many bubbles for your liking, place it lower in the tank. That way it wont get any air to create the bubbles with. Don't place it too low though, as you still want it to agitate the surface a fare amount. You need a decent 'ripple'.

yeh it is the same as the one on the end. will move it lower in the tank see what happens been getting a lot of Condensation in lid and on the sides of tank dont no if this is a factor in it as the bubbles are around the edge
