Faucet and Sink Method

One of the easiest ways to clean dirty sand, accessible to almost every household, is the faucet and sink method. Its working principle is the same as you would use to rinse-clean the rice. The first thing you need to do is empty the sand into a bucket. Then pour fresh water into the bucket.

We recommend making a volcano-type hole at the bottom of the sand for the water to reach evenly, not leaving anything dry.

Stir the sand using your hand or any tool, and then rinse off the water in the sink. Repeat this at least thrice until you feel the water is clean. There you go with the easiest way to clean your aquarium sand.

Garden Hose Method

The first step is the same: pour the sand into a large container and add fresh water. Overflow the inside of the container/bucket with the hose in a way the sand is agitated. Let it happen until the dirty water is gone

How To Clean Aquarium Sand With a Siphon? 

Siphon is a necessity for every fish owner to have in hand for fish tank regular maintenance and regular water changes. And if you’re new to the fish pet world, you might ask, what exactly is a siphon?

Well, the siphon or a gravel vacuum is an effective tool to eliminate fish waste, debris, food waste, plant waste, and dirt buildup on the gravel. It is also helpful for changing the water of the fish tank.

Aquarium siphons can be found in different sizes and designs, all ultimately serving the same purpose. You will need to get one according to your needs, like the size of your fish tanks, the number of fish, and the number of plants. How to siphon a fish tank would be the next question in your mind, and here’s how:

  1. Firstly, you need to take the top of the siphon/gravel vacuum, which looks like a tube and dip it inside the tank to fill it with water. Make sure to fill it out completely with water.
  2. The next thing you ought to do is cover the bottom of the hose with your thumb. Hold the tube straight, and take it as high as possible.
  3. Keep holding it till you see the bubble formation, as those bubbles will be responsible for the suction.
  4. The tube should be half empty by now. Immerse it again inside the tank while letting the end of the hose loose(by no longer placing the thumb on it) into the bucket simultaneously, creating the suction.
  5. Now roll the tube over downwards, and press it against the rock bed. This will instigate the procedure of vacuuming your fish tank. And while doing this, the tube will also suck rocks. Shake the tube to get those all out, so to prevent the blockage of the hose.
  6. Keep doing it until you’re sure all the sand surface is cleaned. And that’s how to clean aquarium sand with a siphon gravel vacuum.

Siphon is also used to change the water in the fish tank. Don’t forget to use a water conditioner while changing the water in the tank. Because if you directly let the tap water in, it will be akin to deliberately contaminating the tank water quality and ruining the clean sand.

Using Sand Cleaning Fish To Clean Your Fish Tank Sand

Ever heard of fish that could be used to clean the fish tank sand? No worries, we’re about to turn a novice fish owner into a pro.

There are certain fishes that serve the function of cleaning aquarium sand. Introducing these types of fish to the aquarium keeps the tank clean, safe from harmful bacteria, and keeps it healthy for longer.

Let’s talk about the most common Sand Cleaning fishes used by fish owners and recommended by Aquarists.

Corydoras

Fishes don’t put their food leftovers in the fridge to microwave later; it gets left in clean water. Uneaten fish food can decompose into nitrate and ammonia, clogging the filter, affecting its efficiency, and lowering the PH level of water inside the tank. Which in turn becomes the abode for mold and fungus.

To avoid this, introduce the Corydoras fish into the pond. Corydoras is a type of catfish that works efficiently to keep the aquarium tank clean; truly a hard worker.

They could work as detectives, for the skill they have to look up for any last morsel of food. Corydoras belongs to the Almond catfish with various fish species. You will need four or five of these in your tank.

This catfish continuously digs and root through sand/gravel in search of any sign of food particles. While doing that, these fish stir up the dirt, aiding the filter to pick it up and thus significantly contributing to keeping the sand clean, aquarium too.

Loaches

Loaches are a type of scaled fish belonging to the superfamily Cobitoeda. Loaches work on a similar principle as Corydoras; they also root at the bed of the fish water tank and try to dislodge any trapped food particles, thus keeping the outer layer of substrate/gravel cleaner.

However, they aren’t essentially catfishing like the Corydoras.

Loaches tend to grow much bigger in size. The largest size of the loach that you can find will be the Clown Loach.

It is a tropical freshwater fish that can grow up to about one foot in length. Indicating that you will need a bigger aquarium to keep them functioning properly. The smaller congested aquarium will stress these out.

Moreover, Loaches are fast swimmers and move in an agile manner. They like to stay together in groups to wipe out any trace of uneaten food.

Geophagus

Sand-cleaning Geophagus is totally different from the above species. Its name Geophagus means earth eater, which in turn reveals the method they use to eliminate any trace of uneaten food.

What they do is pick up a chunk of sand and gravel in their mouth and then filter it out of any food present. This makes them ideal because the sand/gravel is turned over properly, and thorough cleaning of the aquarium sand is ensured.

Aquarium sand is preferred as a substrate if you intend on introducing Geophagus to the aquarium. Why?

Because of the chunks they take into their mouth, gravel can cause clogging in their mouth or gills. It’s best to keep them in adequately/large-sized tanks, preferably with the fish species belonging to their habitat region, Central or South America.

There are a lot of species available of Geophagus. They tend to be more expensive than Corydoras catfish and Loaches, but the money is worth it for how well they do their job. Not to mention how spectacular they look, even when they grow old.
