thank you!
So I put some water in a clear jar (big one, the kind you get dried shredded pork in) and started airating it with some crazy air pumps, heated the water to 78 degrees, and put a little baking soda in. The pH was pretty close to the display tank's pH. My pH kit sucks, but it definitely was close.
After I setup a 8 gallon tank, heated brand new mixed reef crystals / instant ocean (ran out of rc, had to get io from petco) to 78 degrees, salinity at 1.026 (per refractometer).
Maxijet 900 in there, kind of rough though. I was going to use a small little 100gph pump but it won't turn, (damn quiet one). Anyway, the water is about 6.7 gallons in there now, so the directions on the copper said 1 teaspoon per 4 gallons, so I added 1 tsp plus a tiny bit. I don't want to overdose.
So this is how it went:
Netted her (not too hard) while she was eating. It's a good sign that she was still able to eat! Then I plopped her into the jar. She immediately locked up, fully bent and fins as far forward as possible, breathing REALLY hard. I was freaked out! I was going to take her out and put her back into the display, I thought she was dying. But right when I was about to dump her back out into the net, she moved and started swimming a bit. Then she freaked out and swam in circles, tried to jump out (good thing I left the net on top)... then calmed down some more. I saw a lot of white stuff floating around the water, and it definitely couldn't have been the baking soda. It looked like white dust, some bigger than others. I think that it means it's definitely marine velvet.
The biggest one I could see might have had little frills, but that might just be me freaking out adn thinking it has tiny feet. So after 4.5 minutes I got her out of the jar and into the freshly mixed water laced with 1.15 teaspoons of the copper I bought from Petco called CopperSafe. I hope that's a good brand, it was the only copper Petco carries.
I put a light on top of the tank, not sure if I should keep it on. If it's dark she might be more freaked out, I dunno. I'm going to go out and get some food now and I'll try to feed her tonight if she's not totally weirded out.
I didn't put any filtration in the tank at all. I heard floss / live rock will absorb the copper and render it useless. The copper says it can treat the tank for 4 days, and no water changes necessary given all parameters are good.
Should I change the water? Should I redose the tank with the amount of new water I put in when I do change it?
I'll probably check water params twice a day, and do a water change if necessary if you guys think it's a good idea.
