Bubbles are they a bad thing?

[Rhyn]

I have a two tanks on top of each other. so water is pumped from the sump to the top tank which overflows into the bottom tank and this causes lots of bubbles. These are not display tanks so i dont mind the bubbles but are they causing any harm?

ps: love the site, so very helpfull. Thanks all involved!

There are no chambers in tank displays

If theres no livetock in the tank, then besides splashing and salt creap they shouldnt cause any harm.

Yes they can be, they can cause the fish to show symptoms like air bubbles under the skin by the eyes etc which looks like pop eye @Nemos Janitor can elaborate since he told me about it

Yup it is called emphysematosis. Normally caused by super saturation of O2. Like the bends divers get, but for fish.

"Yup it is called emphysematosis". Gas bubble disease in fish however it can be from supersaturation of Air including nitrogen which the majority of air is IT is usually not caused by large bubbles from overflows but from a pump which is sucking in air and super saturating the water with air to such an extent that it allows microbubbles to come out of solution inside fish and coral tissues



The bubbles made in your pic are not likely to be bad problem though as i doubt they super saturating the water with air
