Keeping it Simple
A Story of Stability
A Story of Stability
Overall Summary: The tank is coming close to being 4 months old, and overall, it's doing well. Growth is nothing to write home about (although still there), but the colors are looking good. Chemistry is still the big challenge,of course.
Alkalinity: Typically, I keep my Alk around 8.6-9.0 dKH. My tank's not an ULNS, not yet, so I feel comfortable keeping it at this level. I may taper down to 8.0-8.3 dKH, over time. I believe I shared that I recently started adding Kalkwasser via a BRS dosing pump. Corals were growing bases quickly in this range. Well, one day I switch my dosing outlet to ON on my Apex Jr., and I forgot about it for a solid 12 hours. I think I dumped 2 gallons at saturation, which resulted in a 1.0 dKH increase in 12 hours. Nothing seemed stressed, and I was curious how the growth would be at a higher dKH. Because of this, I left the level at 9.9 dKH and switched the outlet back to AUTO, to keep up with consumption. I was stupid to not check my Alk for over a week. I noticed my canary coral, Purple Stylophora, was receding, so I checked my levels. Tonight, I'm at 10.9 dKH. That means my consumption rate has dropped; I had also noticed slow growth, indicating the same. Either the quick increase or the stable, yet high, level shocked the corals a bit. I turned the dosing pump off, and I'll be letting the system drop naturally.
Calcium: I have checked Calcium in quite some time, since it's been solid at 440 ppm for a long while. But, since my Alk was high, I thought I should check Ca as well; after all, if the carbonates aren't be utilized as quickly, then neither is the Ca. Sure enough, it tested slightly over 500 ppm. Luckily, turning the Kalkwasser off will remedy that situation as well, over time.
Nitrate and Phosphate: I inspect the tank daily to check with my eyes and make sure things look right. The colors are looking very nice; an Austera (I believe that's the right spelling) has changed from brown to purple, while a superman Digitata has changed from brown on brown to orange on light blue. That definitely has been encouraging. Overall, every coral has shown increased coloration.
that leads me to believe that my Nitrates are decent. On the other hand, even at its high point, growth wasn't amazing and there's still a few small patches of hair algae. From this, I'm concluding that my Phosphates are still a bit high.
Upcoming Additions, Feedback Needed!
The first thing I'm considering is building an Algae Turf Scrubber to better export the N & P. I would be using red and blue LED's and build most of it out of acrylic. Any thoughts or experiences?
Lastly, I'm thinking about going back to the Dark Side. I'd like to build an LED fixture unlike any other I've done before. It'll be very different than what's out there, in some big areas. I'll also be testing it in my sump; that's at least 6 months away.
