Hello R2R. Havent been on here in a LONG time. So, here's an update. I've completed a re-boot over the summer and fall and have things turned back around. Long story short but life got in the way, busy at work, combined with incorrect math on my part and the gradual decline of my LED's, all this led to a 48month very slow regression of my tank in general. In fact I lost nearly all my corals and micro-fauna. I understand through many years that there is sometimes too much information out there that tends to muddy the water to the point where too much money can be spent and confusion can prevail. Replaced lighting, ditched some equipment, simplified the system, and considerably ramped up my maintenance regimen, and my tank is now doing well again. Time will tell, but its been since the end of August since ver2 launched and so far so good.
