LFs at SG 1.021

[Daddyrawg]

he has his fish all in SG of 1.021.

is this a good thing?

That is based on perspective.

Keeping sg that low cuts the cost of salt which he could use the saving to offer a wider variety of fish.

On the other hand it makes acclimation that much more important because if not done properly the fish could suffer osmatic shock. It could also mask problems like ick.

Good or bad, don't know... but it is pretty standard for the fish tanks in a store.

It would be bad for inverts, obviously.

 

[Daddyrawg]

yeah he mentioned id have to drip aclimate

While keeping the fish at 1.021 does save a little money on salt, the main reason fish stores keep their salinity in the 1.020 range is that is the salinity that fish are shipped at. Lower salinity reduces the toxicity of ammonia. When fish are shipped from the collection sites around the world to the wholesalers here in the US or Europe they are shipped in lower salinity so the ammonia that builds up in the fish's bag is less toxic and the mortality rate is much lower. Wholesalers do the same thing, they keep their fish in water that has a salinity of about 1.020 and then ship it to the local fish stores in low salinity water. Your local fish store thus keeps the water at 1.021 so they do not need to acclimate the new fish that they are constantly bringing in to their stores.

There is also more oxygen disolved in lower SG, making respiration easier and stress lower.

Well I just learned something new. Good to know!

I believe the osmotic pressure to balance salt is much easier on the fish and less stressful.

I keep 1 of my QT tanks at 1.020 when getting new fish. As water evaporates over the 3 days before transfer, the salinity rises. I match the second Qt tank to that. After a few transfers I have it up to 1.025 which is what I keep my main tank at.

Same here.



During TTM I don't replace evap until I'm on like the third transfer where I'm usually pretty close to 1.025.
