Hello all,
I am new here and this is my first ever forum post. Looking for information on these bubbles here, they started hanging around a day or so after installing our sponge filter. It’s been a week and there has been no change with the bubbles. This is a 29g tank, currently only stocked with plants and 6 guppies.
Previous water test have come back okay, with a slightly elevated water hardness.
I’ve read about elevated protein levels in the water that can cause this, and to do frequent water changes until resolved. Is this true?
TYIA for any recommendations/help.
