Why Is My Aquarium Gravel Always Dirty?
There are several reasons why your aquarium gravel is always dirty. Here are some of them.
- If you are not regularly vacuuming your aquarium gravel, debris will accumulate. This debris build-up will give a bad look to your tank’s gravel.
- Overfeeding causes food leftovers. This leftover will accumulate at the base and make the gravel dirty.
- Inefficient or inadequate filtration also causes debris accumulation at the bottom.
- Higher population density caused the dirty gravel due to high waste production.
- Decaying plant matter also adds dirt to the tank’s gravel.
- The algae bloom in the tank is another reason.
- Irregular or less frequent water changes, i.e., less than 10% weekly, cause dirty gravel.
Impaction of Dirty Gravel
Dirty gravel in a tank not only deteriorates the tank’s look, it also harms in many other aspects. Here is the impact of dirty gravel.
- Waste trapped in gravel on breakdown releases harmful gases and raises nitrite and ammonia levels. This results in lower water quality.
- A large organic material decay trapped in gravel causes ammonia spikes in the tank. Ammonia spike leads to bad sceneries in the tank.
- Dirty gravel is a haven for harmful bacteria. These bacteria cause infection among fish and other aquatic pets.
- It increases the water cloudiness, ruins the scenery, and the tank loses its aesthetics.
- A thick dirt layer restricts the proper water flow. This reduced flow rate leads to lower oxygen levels in the tank.
- The previously discussed aspects also cause stress among fish and other aquatic pets.
Why Should I Clean Gravel in Aquariums?
Gravel cleaning is necessary for many reasons.
- Improve water quality
- Avoid ammonia spikes
- Increase oxygenation level in the tank
- Improve the aesthetics
- Avoid stress among the fish
- Avoid bacterial diseases
