Salinity of your tank

Mr. Limpid · Mar 21, 2018

I had a discussion with my LFS and he runs his tanks at 1.0108 claims this better for parasite control. I said he just doesn't want to spend money on salt mix. I run my DT the same as our oceans which 35PPT or 1.0206. So I would like to know what you all are keeping your tanks at and you can add if you like a description of why. Thanks in advance.

Many shops run their tanks at a lower salinity; oxygen content is another reason. Most people with reefs, have it considerably higher (35ppt).

Yep, lfs, public aquariums run their fish systems at a lower salinity. Helps with parasite control, oxygenation, and lower salt costs. However, you cannot keep a reef or any tank with inverts in it at a lower salinity for long. They will not survive. I keep my reefs at 1.025 specific gravity.

35ppt here.

He is right, the lower salinity for fish only tank does help with parasite control. However, for a reef tank the range you want is 1.025 or 1.026 specific gravity.

So its fine to run fish only or reef tanks at 35PPT (1.026). Thanks all.

I run my reef at 1.025

1.025. That is what both LFS within in a 5 mile radius of my house run and that is generally considered to be the sweet spot between fish and corals.

1.025 for this guy

bo0sted2g · Mar 22, 2018

1.026 for me

35 here, the lower salinity at the shop will be for the fish.

PatW · Mar 22, 2018

I run at 1.026.

My tank is 1.025 then when water evaporate might hit 1.026 then I fill up the sump and back we go. I have definitely heard of LFS keep lower salinity to control parasites. The owner of my LFS just told me recently except coral tank the fish only tank are at 1.014
