W/C's and drop in SG

[bv_reefer]

-just wondering what do you guys do when you have to do a big water change and you're SG drops, do you're fish and inverts such as corals,anemones, and crustaceans get really stressed with the decent drop in SG? -i just found a snail thats been dead in the same corner for a week and it gave out the most putrid smell i've ever encountered, and i'm guessing it could also be part of my cyano-outbreak thats plagueing my sand..

I think most people here match SG BEFORE doing the change.

There should be no change in specific gravity when you do a water change.

i did test it before, it waz at 1.023 now it's at 1.021 if the hydrometer is right, but it was a bigger w/c at 20%

[SeaHorse_Fanatic]

I have found hydrometers to not be very accurate.

:ya thats what i thought to, but i tryed 2 times with the same reading, 1.019!
i bumped it back up to ~1.021 for now

his sig says "33-gallon mixed reef & freshwater cichlid tank." So it must be like a brackish tank.

Its also a good idea to let the newly MIXED SALT WATER age for a day or so before adding it to your tank.

I have never heard of anyone adding fresh ro water to a marine tank when doing water changes. Just cause you have "always" done it that way doesnt make it right. No wonder your SG isnt stable.

Or its marine before the water change and then cichlid tank after the water change.

Hey could it be possible he has used the term Water change when he meant water top-up.

BV-Reefer were are you?
