Things are slowly recovering, enough that I've felt comfortable buying some new frags to fill in holes left by my old corals.
My biggest issue recently has been keeping my macro elements up, however. I've been extremely time poor recently, so I've only been testing once a week, before a water change. If the levels have been low, I up the dosing rate, do the water change, then test again the next week. I know i should be testing before and after the water change, as well as testing the newly mixed water, but I'm getting tired of every single Saturday being taken up by this tank, and have other things I don't have time in the week to do in my house as well. Grrr.
This week I was floored. By yesterday morning my levels had cratered:
dKH: 5.9
Calcium: 303
This is after doing two water changes last weekend (Saturday and Sunday), and upping the dosing rate. My magnesium test is well and truly expired so I don't trust it, but it claims I'm in the 1250-1300 range.
I adjusted the alk up in to the low 7's, and calcium up to 360, then did a water change. I also upped the dosing volume by 15 mL/dose, then did a water change. I'm up to a grand total of 600 mL of Tropic Marin Part A and B balling salts
PER DAY, mixed to the concentration specified on the box. I'm going to have to switch back to less expensive bulk chems.
This morning, (24 hours later), alk is still good, dKH of 7.11, but calcium was back down to 303! These levels are too low and too balanced for me to be having a precipitation issue, the only thing I can think is that this batch of H2Ocean has absurdly low calcium. I'll have to mix up a batch to test it.
These wild swings can't be helping anything, and I've got some STN at the base of an A. abrotanoides that I think might be a symptom.
Anyway, here's some crappy pictures. I dropped my new iPhone and cracked the camera lens, but won't replace it until the case I want it released in Canada. I'm notoriously hard on my phones. These pictures are blurry, and the colour balance is WAY off.
Thankfully my Pink Lemonade frag never had any damage through all this and is now a mini colony
The lime green stag on the left used to be a colony that almost left the water, that's all that's left, but it's growing. The purple battered looking thing is all that's left of a plating acro from walt smith, but it's started sending tissue out over some of the dead areas again. The rest are frags I bought to fill in the worst hit part of the tank.
These two frags are all that's left of a dinner plate sized colony. They were the underside of the old colony, so they were brown and have never been exposed to light. It was touch and go for weeks, but they turned purple in the last couple of weeks, and there's the tiniest hint of growth. I'll move them up in to the rocks soon
This poor guy.. I don't know if he'll ever be the same. Before this disaster the stalks were glowing white, with neon green polyps, and electric blue tips. It's growth pattern is all messed up as new growth tips start at odd angles from where things died. That monti is out of control
Nearly lost this guy but it's got all sorts of new growth
Randomly, this guy never even slowed down, grew right through that disaster as though it ain't no thing.
Only thing I can think that explains my trouble with the chems is those montis everywhere. They weren't damaged by what happened at all, and have EXPLODED. I stupidly put pieces of that big red monti cap that I broke off doing normal cleanings in a couple of places and it's turned in to a major weed. I just throw those pieces out now. I can't imagine how much calcium and alkalinity it must be sucking out of the water to grow that fast alone.
