How Do I Clean Fish Tank That My Son Dumped Cheerios In?
The majority of the beneficial bacteria you need in the tank does not actually live in the water but in the gravel, decorations and filter. You have a good start on getting things back to normal. I would do 15-20% water changes daily until things are back to normal. These smaller changes will help clear the water up. If it is a cloudy white it is possible that it is just a bacterial bloom that was triggered by high levels of dissolved materials from the cheerios. The regular changes should help to ensure your fish don’t suffer and take care of the problem in short order.
