Salinity Level

Tonight I did a 30% water change in my 125 gallon tank that has been up and running for about a week and a half because of high levels of ammonia, nitrites and nitrates. I had these levels tested at our LFS and that was their suggestion. Before the water change, the salinity level was at .022, after water change the level was just below .016. I have added a good amount of salt since the water change and have re-checked the level a few times and it barely seems to be coming up. I do have 3 fish, a starfish and some crabs. Is this sudden change in salinity going to be detrimental to them?? And how long do I have to get the salinity level back to normal before it starts effecting them???

Did you cycle your tank? Im more worried about the ammonia and nitrite killing your fish than SG

Well, we were told from our LFS that we could add fish 24 hours after starting up the tank as long as we used a product called Stability. We had it up and running a couple of days before we added fish. The funny thing is, all of our LFS (and we have 4) told us the same thing about adding fish that soon. They all said that it would be safe and good for the tank to add fish. I'm getting very frustrated because I don't know who to trust anymore!!!

Trust us here at AA.

I generally say, Take what your lfs says for a grain of salt until proven true.

Ask us here. Lfs's are businesses that are looking for a sale. They just want the money, usually. We don't want your money, we just want your fish and you to be happy.

Will the water change I did today increase the chances of my fish surviving? Our LFS said to bring a water sample back in 24 hour after doing the water change to re-check our levels. When we do that, we are going to buy our own testing kit. It seems the more I read, the more I learn of LFS not testing water samples properly and giving their customers false readings. I know our kit should include Nitrites, Nitrates, Ph and Ammonia. Anything else important that should be added to that list?

Thank you for that, I think I know better now!! Unfortunately, what's done is done and I need advice on what to do now so I don't lose my fish!

Uh huh. With an in fish cycle, water changes are your best friends. I can't help much, because I have a limited knowledge on saltwater. I'm just starting freshwater.

I would take advice from the more experienced saltwater people than me. If I can help at all though, I will.

I would return the fish to the LFS and do a fishless cycle. Fishless cycling is easier, faster, and cheaper. Doing daily or every other day PWC's on a tank that big will cost you a lot in salt, and it also slows down your cycle.

I dont know much about how to solve things since I am still a noobie at this, but posting up information about your tank would help others who are more knowledgeable.

How big is your tank? amount of live rock? dry rock? sand? filtration? what kinds of fish? how have you been adding salt, mixed or just adding it to the tank? powerheads?

I can tell you right now adding any fish to a SW tank in 24 hours isnt good unless your moving from an old SW tank to a new one.

Your ammonia, nitrite, and nitrate are all high right now due to the tank cycling.

Here is a great article about it:
Cycle your salt tank

If you did get expensive fishes, I would try to return to get store credit so that you can re add them later. Tell them that the advice they gave you is clearly wrong and that if they believe that they can add fish to a brand new tank, I would like to see them try it for themselves. Adding fishes to a SW tank that hasn't completely been cycled is very disastrous due the the fishes being extremely sensitive to changes in ammonia, nitrite, etc. Some people can be lucky and add fish early in a FW tank, but that is still ill-advised since putting any fish in dangerous water is wrong.

Also, the API saltwater test kit is considered the best in most people's opinion. It's a liquid test kit, and the strips are notoriously inaccurate.
