A guy in the local club has lost most of his fish (a tomato clown, an angler, and a naso tang). His yellow tang is still kicking, so it's not a total loss.
As near as we can figure, it's because he added all of these too fast and didn't let his tank catch up. He's running a 75g with a HOB
skimmer. He added each fish with 2 to 3 weeks in between. Right now most of his water parameters are ok except his nitrites are high (which likely killed his livestock).
Anyway, is there any way to watch these mini cycles after adding fish? From what it is looking like to me, you can add a fish but the nitrogen cycle that starts from that one fish is pretty small (too small to see on the testing kits?). The bacteria will build up some more, and then you can add another fish.
It seems like if you can see much of anything on the test kits, it's pretty much too late. Is this right?
I'm running a 75g with a 29g sump, so my system looks alot like his and I don't want to kill anything.
