Copper's very close to .25 now, and may even be a little under. I would guess that last Friday it got to at least .3
, 40lbs of sand. I'd estimate 2 gals for the Fluval 304 system. I also keep it very full because the Eclipse system is much quieter that way. I generally treat it as a 40 gal
Impossible to say how much copper's in there. I'd just completed a full treatment cycle and added the carbon and done a 9-gal
water change, plus I'd done a couple of changes with copper-treated water during the first treatment.
Additionally, the copper was not stable at the start of either treatment cycle, which may have been related to the bags of coral in the Fluval.
It seems very stable now. I did a 6 gallon, a 4 gallon, and then a 3 gallon change all since Friday, without adding any more copper.
Gramma and the Firefish have been very shy, though I actually saw all the fish briefly this morning. There's been a little itching. Nitrates still higher than I'd like (mid 30s). (Does that go up when the carbon's been removed?)
Tang's still a little streaky and his color's a little pale, but he's not clamping nearly as much.
Looks like someone's been nipping at the Gramma a bit. Either he tried to hide in someone else's hole, or he's been letting the Tang get too close because he's off his game. Usually he just steers clear of the Tang and there's no conflict, but the Gramma may not be feeling too good right now.
I think I saw a single spot on the Tang's right fin yesterday, and it's gone now. This is the first time I've felt the bug's really in decline since I started adding copper two weeks ago.
How long must I treat to eradicate it?
