Only in the last 3 years, with a 75G tank on my back poarch. In the last six months, I am cycling a 135G lagoon theme tank with an extreme sandbed that rises from 2" to 12".

subsea Posted October 10, 2012 Author Share Posted October 10, 2012 Great read hey what in your mind is The best sand For The job It depends on what the job is. Do you want to feed fish or coral or NPS? Some natural methods may well do all three. For maximizing diversity, the bulk of substrate should be similiar to Caribbsea Special Reef Grade Arroggonite 1mm-2mm. I find this somewhat large for the worms and would include up to 20% of sugar sand. In my 135 gallon lagoon, I also included a substrate from Seachem fresh water products that is high in iron. If I do not have to dose, I will find another way. Link to comment Share on other sites More sharing options...
subsea Posted October 10, 2012 Author Share Posted October 10, 2012 If you had a DSB on top with a mud filter combined with a vegetable filter on bottom, you would have a perfect NPS SPS or lagoon system. Link to comment Share on other sites More sharing options...
