  1. if you had been using MH or T5, and then put your LEDs at 100%, you *will* kill all your corals.

    Victoly, *Will* seems pretty convinced. Now I'm not claiming to be an expert just sharing my experience, but I recently switched from MH to LED and did no acclimation at all. 6 weeks later my coral is still doing fine. No bleaching at all. I have zoas, gonoporia, mushrooms, candy canes and torches and a few other unidentified pieces. Am I lucky or do I just have less sensitive animals?    
    Maybe your LEDs aren't as powerful as you mh was. Several factors but I would still consider yourself lucky.
  2. It's really easy to build one yourself. Austin plastics (I think that's what it's called) has everything you need. And cut to order. Then you just "glue" it together. Easier then glass.

  3. Since you would need a new stand (because the existing frame probably would fall over time) you could accommodate the wider tank and just put sheet rock over the new wood frame. Then adding the top of the tank to match the surroundings. Not too hard todo. I have a 65" wide tank so I bet you could find a tank to fit. Or make one. That's fun diy too.

  4. Are hydrometers random? If sample A constantly reads 1.025 and sample B consistently reads 1.021, doesn't that imply it is not just hydrometer error?

    That said, unless your are having major salt creep, or having a leak, I can't imagine wat it would be. I would not figure rock would be eating it. But I have accidentally lowered my SG by acclimating fish, discarding the water, and forgetting until I top off with fresh water. Cat went swimming and did it once, to.

    For what it's worth (I haven't admitted this one to anyone here) but to raise my salinity I just let the water evaporate to the SG I want and then use SW to top it off. Seems easier to me than to mix SW to various levels and doing lots of math.

    Not necessarily. There are variable with the hydrometer that don't play in so much as a refactometer. Ie not rinsing properly. But I don't think it's a big deal. How old is the tank? Ime new tanks take awhile to settle down. After a few months of keeping it at 35ppt or what ever your shooting for, it seems to stay pretty steady. I would check it against a refactometer.
