For years been reading from people like Calfo and Fenner amongst others that mixed reef don't work long term because of allelopathy. Everything goes great for a few years then systems crash for no apparent reason.
Even just with different softies believe is a issue. For a while my tank was over run with Xenia to the point was throwing it out, got into a few different types of mushrooms and zoos and the Xenia just started to fade away. Around the same time had some Alk spikes so was thinking that, but alk been under control for quite some time. Seems once I started being steady on the carbon the Xenia at least is staying though not growing as before. If only had the will to stop changing things to narrow causes down.
