The Reef Aquarium With Low Magnesium - What Can Happen?

Hopefully you will understand that keeping corals is a huge responsibility and can become very expensive to yourself and the environment. Corals are very interesting animals and unless you are willing to nurture them properly, you should find another hobby.

After checking the usual, Salinity, Nitrate and Phosphates. You should be checking Magnesium, Alkalinity and Calcium. These three parameters are very important when keeping short polyp stony,and long polyp stony hard corals, SPS and LPS respectively.

So what effects will low magnesium have on your reef aquarium?

You will find it very difficult to maintain high alkalinity and calcium levels if magnesium is low.

Corals will slow in growth and will cause some corals such as Duncans and torch corals to recede, and in some cases die.

The second cause of that should not happen if you are doing regular parameter checks, is high phosphates. Simply resolved by the use of media such as rowaphos. It has to be said that this can be placed in the bag provided into good flow in the aquarium. Better methods include a fluidised reactor, although this creates additional cost but is a much more effective way to deal with the problem.

The final method i have read about is the actual lighting period, Too much of it will create this algae …
