Are the fish is in qt
? If so, no worries you can beat it.
If they are in qt
, you can reduce the SG
pretty quickly. I would change out 1/5the of the water volume in the qt
every 12 hours with fresh RO
water. Fish can take a fast drop in SG
, but cannot take a fast raise in SG
The hydrometer will be OK to start, but to do an accurate treatment, a good refractometer is needed.
will do some funky stuff, especially while you are adjusting the SG
down. The buffers you mentioned above will do a fine job in keeping the PH
stable during the transition. Your best bet is to buffer the change water before you use it. Also test daily for ammonia, it will spike until your biological catches up with the treatment.
Please do not attempt this treatment within the main. A proper qt
setup the most important component of the treatment.
