salinity?

I kept that in mind.So, I brought home a full bottle. There was no room for evaporation.

ah smart So maybe we should be keeping our salinities higher, but for me its hard to actually keep it that high for my small tank because i do not mix my own salt and the LFS sells water with the salinity being around 1.025

i have one lfs that mixes there s at 1.023 and another at 1.026 ....i mix my own
but its looks like the answer is pretty clear here

crap I'm half asleep here and for some reason voted wrong
I try to keep mine around 1.024 but I have been told that most of the oceans are 1.025

Note to self, more research. Dang, my Coralife Hydrometer has the 1.020 - 1.023 marked as ideal. My salinity is at 1.021 and I thought it was fine. I will start doing water changes and bring it up gradually. How many days (weeks?) do I need so I don't shock or kill everything? I have Red Sea salt and will get RO water because my unit is on order
pH 8.2
ammonia 0
nitrite 0
nitrate 0
calcium 480

There are 2 schools of thought as to why this will kill ich. Both are based on osmotic pressure. Its just which part of the parasites lifecycle is affected/disrupted. One says the lower salinity causes free swimming Theront to rupture, killing them. The other says that the reproductive stage (Tomont) needs a higher than available osmotic pressure to push out the Theronts and they end up dying because they cannot "hatch".

I am not sure which is right. I just know it works.

at what point will you have to worry about FW ich? what is the salinity variability of the two different ichs to survive?

Nonsense post because I need 20 to post a picture, sorry.

As far as survivability, that's a good question and I honestly do not know the answer. But it would be virtually impossible for FW ich to enter a SW system or visa versa. FW and SW Ich carry the same name and look alike when on a fish, but that's were the similarities end.

1.025 always..-drew

I've read that too high of a salinity can effect the scales and mucous membranes of a fish. If salinity is too high can be harmfull. Ive been trying to keep mine at 1.024/25 per most recommendations
