Picture: Pleco Tasting Moss Ball In Freshwater Fish Tank<\/figcaption><\/figure>\nEvery part of your fish tank set up can be evaluated with a cost-benefit analysis. Not having a fish tank at all would require zero effort and so it would cost you nothing.<\/p>\n
But it would also mean that you wouldn\u2019t get the benefits of having something interesting, beautiful, relaxing, and fun in your space. Filters deliver considerable benefits by maintaining water quality, but they require investments in the form of power to run them and work to maintain them.<\/p>\n
One of the best things about moss balls is that they are light on costs and heavy on benefits.<\/p>\n
#1 \u2013 Moss Ball – Absorb Nitrates<\/h3>\n
Fish waste in your tank leads to the accumulation of nitrates, nitrites, ammonia, and phosphates. Moss balls, like all living plants in your aquarium, help to maintain healthy water quality by absorbing those potentially harmful compounds.<\/p>\n
While a single moss ball won\u2019t be enough to replace a filter in a tank that is larger than a few gallons, it will make a beneficial contribution to the overall effort.<\/p>\n
#2 \u2013 Moss Ball – Oxygenate Water in Tank<\/h3>\n
Like all plants, moss balls use photosynthesis to survive. That means that they absorb CO2 and release oxygen.<\/p>\n
You might even see your marimo floating in the tank as built-up levels of oxygen dissipate into the water. Maintaining healthy oxygen levels in your aquariums water is important to the health of your fish and other creatures. Every little bit helps, and moss balls add to the total.<\/p>\n
#3 \u2013 Moss Ball – Prevents Excess Algae Growth<\/h3>\n
Using algae to prevent algae is the definition of fighting fire with fire, right?<\/p>\n
Because marimo consumes the nutrients that other, less desirable forms of algae would need in order to thrive in your tank\u2014having marimo goes a long way toward eliminating unwanted algae.<\/p>\n
Just as the size of your tank will determine the impact that each moss ball has on the level of nitrates and amount of oxygen, so to will it determine the impact on controlling unwanted algae.<\/p>\n
#4 \u2013 Moss Ball – Harbor Beneficial Bacteria<\/h3>\n
Maintaining a healthy tank is all about creating the right balance between bio-load and filtering.<\/p>\n
We use filters and water changes to combat the build-up of nitrogen from fish waste and other sources.<\/p>\n
One of the most important weapons in the fight against tank water toxicity are the colonies of healthy bacteria that grow in our tanks.<\/p>\n
Moss balls provide a surface to grow on and beneficial seeding material.<\/p>\n
#5 \u2013 Moss Ball – Low Maintenance<\/h3>\n
If you have a tank with fish in it, you have everything that you need to keep a moss ball happy and healthy. They feed off the waste from the fish in your tank, and they don\u2019t need much light to do well.<\/p>\n
They prefer shade, but they tolerate a wide range of light, temperature, and pH levels. They don\u2019t need to be anchored to the substrate, so you just have to toss them in, and they\u2019re good to go.<\/p>\n
Since Cladophora absorbs so much from your tank\u2019s water, they tend to bite off more than they can chew. That means that nasty stuff will leach out unless you \u2018re-set\u2019 them periodically.<\/p>\n
All it takes to do so is give the moss ball a squeeze over a sink or bucket during each routine partial water change.<\/p>\n
Squeezing the water out of the moss ball means that it will float when you put it back in the tank. This isn\u2019t harmful and only lasts until the moss ball absorbs enough water to make it sink.<\/p>\n
You can accelerate the process by giving the moss ball another squeeze once it is back in the water in the tank.<\/p>\n
The only other thing that it takes to maintain a marimo is keeping an eye on it to make sure it gets enough light on all of its surfaces. If you are moving the ball to perform cleaning, then you\u2019ll be moving it as much as it needs.<\/p>\n
But if you start to notice browning or yellowing in the areas that the ball is resting on, just give it a roll to expose them to the light.<\/p>\n
#6 \u2013 Moss Ball – Adapts to High pH<\/h3>\n
There aren\u2019t many aquarium plants that can handle water that is high in pH, but a moss ball will be perfectly happy in water that is in the mid- to high-8 range on the pH scale.<\/p>\n
