I'm still struggling with colors...I think it's a combination of my not maintaining my alkalinity where it needs to be, and probably my bulb. The growth is tremendous, and as you can tell, probably about 50% of the corals colors are awesome, it's just stuff that hasn't done well like my aquadelight, red planet, and pink lemonade that have me frustrated. I also remember a time not too long ago when a lot of the corals that are looking pretty decent right now looked amazing.
The big problem as you can no doubt tell from my pictures is nuisance algae. Bubble algae and hair algae, as well as a new weird reddish growth (3rd picture up from here, with the green/purple acans) that I have never seen, and would love an ID if someone can get me one. I've been running GFO passively in the tank for over a month now, as well as running carbon, and my TDS is still at 0, so I'm not sure if these struggles are just because the tank is only about 7 months old, if something I'm not testing for is in the tank in high concentrations, or what exactly my problem is. My nitrates are at 0. I don't think my skimmer is good enough to do carbon dosing, or I'd start vodka right away to see if that could handle it. Any suggestions you guys have on what I can do to improve this situation would be greatly appreciated.
