Many people in the aquarium hobby get caught up with the very infamous Bryopsis in their tank. Bryopsis is the last thing you want to encounter in your aquarium and so we have put together a basic guide on; how to avoid this situation and how to treat a tank with Bryopsis.
How to avoid Bryopsis
Use a Quarantine Tank!
Otherwise known as a ‘hospital tank’, a quarantine tank will ensure that if you encounter Bryopsis, you have a spare tank for your fish and coral until the water is treated. You can simply acclimate your fish/coral into the hospital tank while you clean out/treat the current tank. Once all fish are out of the tank, you can choose to clean out the water and start fresh, and once complete, add in your fish and coral again. Therefore, having a quarantine tank can be very convenient when you encounter any contamination.
How to treat Bryopsis
For those that don’t have a quarantine tank:
1. Use fish that can help clean out the tank
Some examples of these kinds of fish are below:
– Rabbitfish, Lettuce nudibranchs, Longspined urchin, sea hare
– Parrot fishes like, Siganus vulpinus, Z. xanthurus
– Tangs like; Kole tangs, Orange shoulders, Halfblack and Bristletooth tangs
2. Raise magnesium
You can raise magnesium in your tank to +1500 ppm. Do this by using both magnesium sulphate & magnesium chloride supplements and mix them together.
What NOT to do
Pulling it out – this only spread the spores and makes the roots spread further
A tip to help all marine tanks:
Put fewer nutrients into the tank. By feeding less, you will reduce the bio-load. Then to be sure, use Macroalgae to remove the rest.
