Well it's been some time since I posted anything here. Sadly my tank does not look nearly as good now as it did in my last posts.
Soon after the last of my post most of my acros started to die off, some slowly and some not so much. No testing I did came back with any reason why it would be happening and over the course of maybe a month all but a few tiny frags of my acros had died off and the monties in the tank started to take a turn for the worse. I lost the green cap and most of the digis started to recede. The softies in the tank never really showed much ill effect from what ever was causing the problems. Frustration set in and thinking about all the time, coral and money I had lost I started to neglect the tank. I did not scrape the sides much and only did the basic maintenance needed to keep it afloat. I was resigned to let only the strong survive in the tank and go from there.
Then one day I was in the basement and noticed some brown marks on the wall of the Rubbermaid sump. After closer inspection it was a rusty residue that was falling off a fan I had suspended above the tank for cooling. There was a metal screw in the fan that was very rusted and condensation was causing it to drip rusty water into my sump. I removed the fan and was wondering if maybe this was my problem all along.
It's been a few months since I removed the fan and now my tank is looking better....the moties that made it are starting to color up and grow again. Unfortunately the only acro frag that made it is a small blue milli but hey its something. I can't be 100% sure the rust in the water was the culprit but removing it was the only real change I made and the tank is doing better so I am going to assume that was the problem and move on.
Over the last couple days I have given the tank a thorough cleaning and am much more excited about the tank verses just hoping something else does not die. I guess the lesson I can learn from this is not to always look for just the obvious, If I noticed the rusty fan earlier maybe I would not have had the losses I did.
Well anyways I guess posting this is part of my rebuilding process and maybe looking back at these picture will inspire me to keep working to ensure I have a happy health tank.
