To clean algae from your fish tank

Tank Water: Al least change water once in a week to maintain the PH and other measurement lives like ( iron, ammonia, phosphate). After changing the water if any measurement is not in balance you need special treatment. That is also harmful for your fish.

Filter: Make sure your filter is tip-top. If algae persist after a regular water change. It may be a problem with your filter. A good quality filter is necessary for your fish and fish tank also. 

Nutrients Control: Nutrients are like magnets and algae are like iron. That means any nutrients left are quickly caught by algae. IF you have too many nutrients and few plants those free nutrients help to grow algae. The solution is to change the water regularly. And use limited nutrients to feed plants not algae. Or you can use liquid fertilizer. If you don’t have a live plant you need some extra care. So we suggest having some live plants in your tank.

Take time: The internet will tell you to do this or do that. Those are wrong? No. If you make any change take time to see what happens. Don’t panic. It takes 15-20 days to do any change to your fish tank. Do not make multiple changes at a time that may kill your fish.

SunLight: By photosynthesis trees make food. And it helps algae to grow rapidly. It seems like you are adding music to their dance. Don’t put your fish tank in direct sunlight.

Artificial Light:  

One of the best ways to play with algae is to give less light. If you have a natural plant give light 8 hours per day. If you don’t have a live plant let the fish sleep when you are sleeping. Turn off the light when you are not watching. But if you don’t turn on the light and don’t take care ( in a bin) for a few days.  Some health plants can survive most of them being affected. Then the real Ghost came it’s called “blackout”. This type of algae is so difficult to remove.

Fish Food:

feeding fish

Though the food is for your fish. But you got some bad guests.They eat your waste food and make your tank dirty. So every time you feed your fish make sure you feed it enough. Not much that will help algae to grow well. If you have a good type of filter you don’t need to worry. If your filter can’t, you have to do it manually. Having a good type of filter is also helpful for your fish and you. you don’t need to worry about changing the water regularly. No one likes it   

Water temperature: warm water is a dancing environment for algae. Most probably you have an aquarium heater, You might see some algae around the heater. The advice is to keep it at a good temperature don’t overuse it.

Oxygen: High level of CO2 is helping algae to grow easily. Make sure you have a good quality oxygen pump and it works properly.
