Bringing this one back to life with some answers and results...
I still have a couple low-flow areas with a little algae. The algae is maroon in color and as I said, only in areas with low flow. It is not 'taking over', so hasn't been that much of a concern, just an annoyance. My main concern was the lack of color, growth, rtn on a couple sps, and dissolving completely of a couple zoas - tubbs blue mainly . I am pretty sure that all the coral issues were caused by the high magnesium and ca, and I finally put 2 + 2 together and found the root of the problem.... Salinity... I had been using the same hydrometer for a few years. Although I rinsed it every time with RO/DI, it's reading was incorrect. I borrowed a friends refractometer and discovered I was actually around 1.033-ish when I thought I was exactly 1.026. duh... high concentration of mg and ca from a salt that, when mixed correctly, has these at optimum levels, points to high salinity. So, with my weekly water changes to try to fix the algae issue, I was steadily increasing my salinity and mg to dangerous levels. So I now own a refractometer and have gradually reduced salinity by removing saltwater and allowing it to be replaced with top-off for a bout a week. I'm at 1.026, now and I'm seeing some nice color coming back to my Cali Tort, polyps are extending more during the day on all sps, and my zoas seem to be a bit more 'full'. Ca is about 440 (was 550), Mg is 1400 (was 1750+). It has only been a few days at 1.026, so I am hoping to see more positive results over the next couple weeks. I'll resume my microbacter7, bio-fuel, and coral-amino schedule tonight.
My plan for the algae is to remove the rocks with algae (most have no coral or just GSP) and scrub it off with a wire brush. I've added 5 large mexican turbo snails, but so far, they haven't found the problem areas or are daunted by the workload. They have done a great job getting the glass and other areas as well as a bang-up re-arranging of most everything else in the tank, though.

Looking locally for a new or used refractometer before I hit the online stores.

Bump - Still looking for some shelves.

I am looking for dry rock to work into the marco rock I have for the aquascape in my new tank. I am specifically looking for pieces that have flat surfaces to create plateaus/shelves at different levels in the tank.

I can justify it... PM sent.

I have 2 10" bass speaker boxes that I won't be using.
One is designed more for a car trunk. It is well built, carpet covered, ported, and wired for bridging with very good thick wiring.
The other is thin and designed for placemen behind a pickup seat. I had them in an old Nissan 4x4, but they should fit behind most standard pickup seats. This one includes 2 older 10" Pioneer speakers.
$50 for all of it, $30 each...
Will trade for any frags other than GSP or Xenia.
Pm for pics. I'll post some later if anyone is interested.

These are still available. They didn't get picked up. I won't be on the computer today, but at the house if you want to pick them up.

I can make it. Put me down for 3. Me + 2 kiddos.

I'm glad the lights are OK... That box looks like Ace Ventura delivered it:

Thanks for the response, Mark.
When I ran my Calc reactor before, the kH was a steady 13/14. When it was down (up until yesterday), I used CoralBuilder in my top-off and it was around 7 or 8 each time I tested. I didn't test too frequently. I know that is low, but not dangerous and I didn't notice a swing in kH or ph other than a diurnal ph swing from 8.4 to 8.1. kH is slowly increasing since I have the reactor hooked back up. It has only been 1.5 days.
My understanding of the relationship between magnesium and calcium was a little off. It isn't 'used up' by the calcium, after all. This article I just read helped me out quite a bit:

Have you tested your saltwater mix before adding to the tank? I am surprised by the high ca level in mine. If you get a chance to, I'm curious. I did not get the same reading last year on my first bucket, so I am wondering if they differ that greatly from batch to batch or if I should mix this one up.

Preface: My 75 gallon mixed reef had been set up for 5 or 6 years with a deep sand bed. For the last 2.5 yrs it was on 'self-maintenance' mode with very few water changes and several different types of algae (both good and bad) set in. I used Tropic Marin Pro salt when I did do changes. I finally got the time to get back into daily maintenance, hooked up my calcium reactor, did weekly changes and dosed Kent Tech-m, and started dosing Brightwell's Microbacter-7, bio-fuel, and coral-amino. The algae all but disappeared, but I was not seeing any drastic changes in coral growth (except the lack of growth of xenia which is good...). I switched salt to the Tropic Marin Bio-Actif and saw incredible color and changes within a couple weeks. I started building a new tank and had to move my 75 to another room, so I got rid of the deep sand bed during the move and things got even better. ALL algae issues disappeared.
Things went great for about 8 months, and now the algae started coming back. Some very hardy sps I have had for a very long time has recently stopped extending it's polyps, stopped growing, and losing some color. Several sps frags I recently purchased that were growing and extending nicely stopped growing and some died (rtn) over night. I have not been running my calc reactor because the regulator broke, so I have not been testing calc or magnesium - assuming the calc should be dropping. My phosphates are not showing up on any test I use, so assuming I MUST be not testing with good kits or incorrectly since algae needs phosphates, I had it tested by Bruce at Aquatek with his ridiculously expensive Tunze kit. He also tested very low: .001. On a whim, I tested magnesium.... off the chart... Assuming it was because my calcium was low and not using the magnesium, I got a new regulator and hooked the calc reactor back up. I tested my calcium to get the baseline before cranking it up... IT'S AT 560! How could it be so high when I haven't had a reactor hooked up for over 6 months?!! And why aren't my sps not growing with such a high level of Ca? Lastly... where is that Ca. coming from? Today, I tested my Tropic Marin Bio-Actif mix and the calcium was 560, magnesium was 1200(ish). I am also trying to figure out where the extra magnesium is coming from since my tank is MUCH higher than the freshly mixed saltwater.
I am leaning towards the Bio-Actif salt as the source of my chemistry confusion. They don't tell us what is in it... just that it's good stuff that your coral needs... Thinking I needed to do more frequent water changes to get rid of phosphates that I couldn't find in testing, I've been steadily increasing my Ca and Mg on a weekly basis.
I know a few in this forum have used Bio-Actif for a while. Are you still using it? Have you seen any issues after using it for a long time? Unless someone can identify anything else that I may be doing wrong, I am going back to Tropic Marin Pro or another salt for a while to see if things balance out. What salts do you use? Is it ok to alternate salts? If it is ok to alternate salt mixes, it seems ideal so as to not end up where I am.
Any advice, input, criticism, blatant insults, etc greatly appreciated!

Those dryer duct vents are exactly like I'm planning to do, only I will be venting into the garage behind the tank. I am also building a powered lift for my canopy. We should compare plans!

Update? Are you ok, Don?

Bump - anyone have a working co2 regulator? If you don't have one, is there a particular brand you recommend? I've burned through 2...
