New fish are already stressed from being captured, transferred, & keep in sub-standard conditions. Why add to it with trying to quickly acclimate them to a sg
/ph change that can be as much as 0.006 in sg
and 1+ in ph. Divers slowly ascend when diving at lower depths to keep from getting the bends & I also feel fish/inverts need time to adjust to their new tank parameters.
keeping the qt tank sg
the same as the main can be too stressful for newly acquired fish/inverts unless you keep your main at 1.019-1.022 sg
which is where most fish stores/online places keep their sg
If you keep your main closer to 1.025 sg
then even drip acclimating
for 2 hours can be stressful and can possibly cause osmotic shock in fish/inverts with the rapid change in sg
/ph leading to sickness or death depending on the change in sg
/ph that the fish was kept in.
Personally I keep my qt tank at the same level as the lfs
(ph 8.0 sg
1.019) and slowly raise the sg
/ph to the main sg
/ph of 1.025/8.3 over the course of 3+ weeks per this article
The use of a refractometer
is highly recommended while performing any sg
changes whether if itâ€™s matching lfs sg
level or main sg
level to the qt tank. Adjusting the sg
down is less stressful to fish coming from that environment and slowly raising it a little bit every other day gives them time to adjust. Since you have to keep them in the qt tank for 3+ weeks anyways it just makes sense to me to provide a less stressful environment.
Lastly Iâ€™d get a 20+ gal
qt tank instead of the 10 gal
. As Brenden mentioned a pwc
of 20+% would probably need to be performed on the 10 gal
often even using the transferred filter from the sump. Also I always keep 20 gal
on hand of well aged sw
during any qt procedures in case of emergency.
