Well, I screwed up. TT.TT And my three babies are dead. It REALLY REALLY HURTS, and yes, I'm still having crying fits...but it will not be for nothing. This is what I learned, so perhaps those reading this might learn from my mistakes. I will not repeat them.
1. Do not dose lanthanum chloride (one product name being Phosphate RX) without extensive research.
2. Make dead sure your calculations are correct.
3. Do not dose two bacterial products at the same time.
4. When they say do not overdose, they MEAN do not overdose!!!
5. Do not dose multiple phosphate reducers at one time.
I know, a lot of mistakes all crammed together in one night. And it hurts extra that it's my fault they died. I loved them, especially Spike. So please learn from my mistakes!!!
On a side note, all of my invertebrates appear to have survived my ineptitude, and ammonia, nitrite, nitrate and phosphate are all testing 0 on my API kit. I also get to go to Deep Sea Creations to get a new fish (who is going into qt.) Silver lining? I think so.
Edit: At least three of my four frags appear to have survived, as well. The fourth was already having issues on and off since I got it, so there's a substantial chance that it's done for. We shall see.
