Does anyone have any experience with the ecosystem mud filter? I recently set up my 220 gallon reef with a 40 gallon ecosystem mud refugium. Within the first two weeks two fish I have had which have lived through two moves and a year of neglect while I built my house, died! Another got somewhat sick all while running a brand new U.V Sterilizer. While I initially introduced the mud I left the protein skimmer on full time until the refugium could establish and begin oxygenating the water. After the two week period I noticed at least one good thing my bubble anemone got HUGE and almost started to GLOW. This was an animal that for two years prior I thought would die at any time. Now the thing is actually pretty awesome. It has been about 6 weeks now with no more deaths and things are starting to sprout pretty good. I use reef solution at half dose. The ecosystem method says to quite using additives other than calcium and alkalinity. I would just like to hear from others who have used this methjod and see what they think. Currently I only run my skimmer about 6 hours a day and everything is fine. I have set up a parallel tank that is a 150 gallon right next to it. The difference is I am not using the mud, only live sand in a 55 gallon refugium with a protein skimmer on 6 hours. I have been having a hard time with some Xenia which I put in just as a watch dog for the system. I still can't figure out what is wrong with it. I swithed from reef solution on this tank to SeaChem's reef plus. Any feedback on this supplement. Garf raves about it but I haven't seen anything special in the last 1.5 weeks I have used it except for withering Xenia. Any opinions on these setups, supplements etc. would be greatly appreciated.
