I've been reading a lot - I'm concerned about long term dosing, and if it is a culprit to crashes down the road. Mike, miwoodar, had an extremely beautiful tank and well documented his dosing. He suffered a crash last year and didn't know what caused it. I've read others who have had long term tanks have crashes too and not know why. We all know there are a million reasons why things go array leading to a crash. I've noticed over time most were vodka/vinegar dosing. Coincidence? Very much could be, but I'm still reading into it. Today I use a sulfur denitrator (DIY) for NO3, and GFO/ Lathium Chloride for PO4. It's incredible how much Vodka increases color..... Sulfur has issues too so it's not perfect.
Folks using it - in addition to answering Craigar's questions, could you state how long you've been dosing? Thanks.
I bolded a line above. Tanks don't last. Even looking through TOTM tanks, the pinnacle of this hobby with massive automation and redundancies, the majority of them will go through something catastrophic sooner than later. The list is enormous and reasons for the crashes is nearly as long. 2011, 2012, 2013...how many of us who are rocking an awesome reef today will be still growing that same reef, w/o a major crash, in 2013? The list will be short. I have my fingers crossed that my current path will last a long time but I no longer feel the invicibility I once did. All we can do is do our best and hope that the tank succeeds. My head conjures images of sending a kid off to college...cross your fingers and hope that you've raised him/her right.
My experience with Vodka was much like Kris'. I never had any nitrate or phosphate problems before, during, or after though. One of my initial intentions was to figure out how many drops of vodka would be needed to neutralize a cube of food. I felt that if I knew that then I could bump up my feeding as much as I wanted and still keep a low nutrient tank. Before long I was feeding ~5 cubes of food to 4 fish every day in my 65 reef and my SPS colors were better than ever. Everything was growing gang-busters it soon became time for a larger tank. That was when I began building my 140.
The transfer to the 140 initially looked like a success. I filled it half way with new water, added a temporary skimmer, GAC, some well-cured live rock, and some sand. I then spent 3 weeks swapping water between that and my 65 then I consolidated everything into the 140. STN set in soon after the move and I failed to knock it back as I had faith that my SPS would recover and beat any ailments. What followed were a few months of decline and I eventually lost all of my SPS in spite of some
massive trimmings as I desperately tried to get ahead of the STN. I then threw in the towel and let the tank do what it wanted to do. We were never able to pinpoint what caused the decline. All of the filtration on the 65 was mapped over to the 140 so I doubt it was an equipment issue. The water parms were always good (and double checked by a local guru's kits). It would be too easy to say that vodka caused any of my problems. STN has always been one of those hard to beat/understand things. The only thing I would do differently these days...the first sight of STN...pitch the colony. Of course, hindsight is 20/20 and pitching a slightly STN'ing colony in an otherwise bountiful system seams absurd and goes against my personal inclination to always fight for the underdog. (Don't look at my tank right now as I'm still a guy willing to pull for the underdog. However, I'm currently squatting on a pile of niblets and I'm not risking any large colonies.)
The article linked above is a good one. Regarding dosing rates, it doesn't take much to sway the balance.
