Hyposalinity AND Tank Transfer Together?

[keithhays]

Good advice, thanks. I've abandoned the idea of using TT but will continue with HypoS treatment. I'll go for 1.008 SG and see how it goes. Luckily I have 2 good refractometers that I'm calibrating w 0 SG RODI. Also have marked buckets, a precise ATO & a fairly humid storage space so I think I can keep the SG from drifting upwards.

Believe me, I've read the stickies thoroughly. I chose HypoS over Cupramine due to statements that it will permanently compromise the fishes health & shorten its lifespan. It was compared to using arsenic by some fish harvesters. Any opinions on that?

I am second guessing my HypoS decision now, however, after all the stories of failure I've read. It seems like this fish should never go back in the DT again even if it appeared parasite free after Hypo treatment. Maybe as the only fish in the frag tank? Or after this treatment I could raise SG to normal levels, wait a while & do a Cupramine treatment as backup? Any thoughts on that?

Losing a $25 fish isn't the end of the world of course but I feel obliged to give it my best shot, plus the experience should be valuable as I intend to be a lifer in this hobby.

I have run into several people who calibrated with RODI, unless the manufacturer recommends doing that, it usually ends up incorrect. I would use the calibration fluid if available.

Defiantly.

Copper in a DT isn't a good idea. The LR & substrate absorb & release copper and you don't know when all the Cu is gone. There will also be significant die-off from the LR because of the Cu.

MrTusk: My writing was sloppy. Never intended to copper the tank, just the fish in it. 2 are captured, 1 remains to be. These 3 will be Cupramined in 1 QT bucket at 1.025 SG together. None show symptoms yet. RGramma is in day 4 of HS treatment. So far so good.

Thnx f good advice on calibrating refractometers. However I don't think I can be precise enough with a DIY solution & will use RODI calibration as one of my units was designed for this. Both units are close. I've settled on 1.007 to account for errors. Plus my ATO added some fresh water on start up so I should be good. Maybe this is too low. Time will tell.
