I wanted to increase the micro life on the system long ago. In addition to improve the feed offer for animals, I read that pods can help control dinos. So, I give it a try
In some time I must introduce a Mandarin, a fish that was in my plans from the beginning, and this should help.
About the dinos, after the removal of the sand they really retreated. The spots that still persisted in certain sandbed sites that were kept underneath the larger island have now disappeared. In addition, the overall appearance of some corals has improved considerably over the past two weeks. I have already bought a new batch with 10 new species of zoanthus and palythoas and I should soon put some new sps to test their reaction to the current conditions of the system. If the answer is good, I start coming in with new species of sps next month.
The removed substrate was washed and will now be dried and stored. I must replace it within 4 to 6 months, depending on the evolution of the system and the health of corals.
