noticed that the wate rinside my tank has some bubbles.
i mean frothy white bubbles.
what could be the cause of this?
could this be a sign of water problem?

i have some gravel in my tank .

i do water change about 25-40 % weekly and also siphon the gravel.
anybody experienced this?
 
nope...

nope..
no bubble nesters.
only arowana and some bichirs. and pleco.
am puzzled about the frothy bubbles.
am suspecting maybe my gravel needs cleaning.
am planning to take out gravel to wash thoroughly before putting it back. :)
 
just outta curiosity ( im new to this) how does one go about pulling all the substrate and cleaning it without freaking the fish out, killing bacteria, killing plants (if you have em) and generally reaking havok on the tiny ecosystem youve worked so hard to create and maintain?

i dont wanna hijack the thread so back to the bubbles which i dont have an answer for.
 
Do you use a particular type of water conditioner, if any when you do the water changes? I used to use a stress coat until I realized that it was the cause of the bubbles. I don't if this is your problem, but I stopped using mine (worst money I ever spent), and haven't had a bubble problem since.
 
thanks..

i'm not using any water conditioner:)
my fish are used to my hand in their tank..
so they don't mind my had... in fact they like to wait forme for food. hehehe
i don't have any plants in the tank so noproblem with tanks..
regarding the bacteria. i have 2 external filter boxes and 2 powerheads in the tank so am not worried about the bb in the gravel:)

regarding chlorine.. \does chlorine produce frothy bubbles?
because i experience this onlyon 1 of my tank and not on the other. and i do the same water change for both. really puzzled about this... :confused:

thanks..
 
Another possibility...

Foam happens along lake shores too, in vast quantities sometimes. It is caused by decomposing organic compounds (algae, dead fish, too much food), when mixed with air (from filter or airstones). The official reason is "reduced water surface tension". Try cutting back on feeding or increasing water changes. The foam itself (if that's what it is) is not harmful but it is an end-product of something that should be corrected.
 
Chlorine gas out will not cause bubbles.

As kveeti suggested, it is likely of a biological nature. Tannins, as from peat or driftwood, can also cause bubbles under surface agitation. Try doing 2, smaller changes per week and see if it reduces the bubbles.

For substrate swapping--there are several threads from about a months ago that outline the procedure. It's not complicated, as long as you are prepared in advance. Use the search feature, making sure you're looking in GFW.
