As many of you know I'm trying to keep my mollies allive and well I went to the LPS for some advice and they say that the mollies whould be better of in a brackish setup when i asked him what he was talking about he pointed to a section of the store there was some plants and salt and a bunch of other stuff.( he was really busy at the time) I went home and try to find out what he was talking about and came up short. Can you help me again ?

A brackish set up is kind of part-way between fresh water and marine. There is salt in the water, but not as much as a marine set-up. Mollies do prefer brackish water. Add 1/2 teaspoon Freshwater Aquarium salt (not table salt, not marine tank salt) per gallon of water. You have to be careful of salt buildup, because salt will not evaporate out. When you do water changes, only add as much salt as would be for the water you've removed during the change, not enough for the whole tank again.

Yes, brackish is between fresh and marine water. However, I tend not to judge the amount of salt to put in the tank by teaspoons and such, as it can get risky with wierd salt levels. I guess if you only intend to keep mollies you can get away with it, but if you're seriously considering a brackish setup go out and but a hydrometer, which measures salt levels. It is simple to use and costs under 10 bucks at your local pet store. I keep my brackish tank at about 1.010 (specific gravity). Also, you MUST make sure you top off the tank with FRESH water if you notice some evaporation. Don't add more salt unless you are doing water changes or notice the salt level is lower for some reason. Oh, and by the way, I do use the marine salt, and I don't know why this would cause problems, as long as you don't overdose.
Good luck,
Pat

I have heard of other people keeping brackish fish like puffers and mollie that also use marine salt. If the fish you are keeping are all brackish fish and not a mix of fresh and brackish using marine salts should be fine.

All the salts are the same..so it really doesnt matter the marine salt is alittle higher then the others..aquarium salt is the same as brackish livebearer salt..just a thought

I disagree as I have read marine salts also have some trace elements not found in regular Aquarium salt. I can do some research on this, but it will take time. Have to check with saltwater sites.

The aquarium salt we carry at my place of work is nothing more than evaporated seawater...it even says so on the box. In this case, I would be willing to bet that there are still some minerals and trace elements found in it (although probably not in as much quantity as synthetic salts where the minerals and trace elements are added, but you never know). From the various sources and people I've heard from, I've never known there to be a problem with using marine salt instead of aquarium salt or vice-versa.

I got the following from a site that sell marine salts.www.aquacraft.net
There is other info out there, but this is one of the trace elements I was talking about...
"Magnesium is a major component in the composition of synthetic seawater. At a specific gravity of 1.026/35 ppt @ 78ºF/25ºC there is 1350 ppm of Mg. That is 3.37 times more than the amount of Calcium, 3.46 times more than the amount of Potassium and 20.76 times more than Bromide.

Magnesium salts cost about 3 times more per pound than common table salt. When a marine salt tests low in magnesium, the weight can be made up by adding common table salt."

Common table salt is in fact very close to regular Aquarium salt. G you may have some special brand at the store, but the cheap stuff I have in a cannister does not say it's evaporated saltwater.

Kent Marine also promotes their superior Sea Salts
"Considerations for use: 1) First use an excellent grade of synthetic marine salt (of course Kent Sea Salt is the finest available, but there are some other excellent salts on the market). Some salts are made from evaporated seawater and contain dead plankton and other heavy organics that will foul the water from the beginning. Cheap salt is no bargain!" These are some other trace elements Kent claims to add to their products.
"calcium, strontium, iodine, iron, cobalt, rubidium, lithium and many others."
Anyways I sure wouldn't use my cannister of tropical/goldfish Jungle Aquarium salt in a Marine tank!
