I have a tank with a few mollies in and and I'm going to be planting the tank tomorrow. I'm gonna put some salt in for the mollies and was wondering if Pickling salt would be ok? It doesn't say anything about Iodine on the box. Is there something different about the salt that makes it for pickling?
I was going to use about 3 tablespoons in my 10 gallon but wanted to make sure that it was okay to do so with some of you guys since I'm new to the hobby. Thanks.
pickling salt is typically just plain NaCL... same difference if you went and bought common aquarium salt... Most of the research I have done on my mollies and swordtails indicates you should be using Marine salt.... That is because Mollies like very hard water in addition to the little bit of salt.
My tap water (well water) has a GH of around 20 and KH of around 12, not quite liquid rock, and a natural PH of 7.8... I just add plain salt and it seems to work pretty well..... The mollies and their babies... and the swordtails and their babies ... all seem to like it really well.
I guess I am trying to say, depends on your water and how hard it is already... if it is similar to mine then plain salt works, if it is softer, you might want to look into something like "Instant Ocean" which will harden the water...
A hydrometer to measure the specific gravity of the water would be a good idea... I think 1.003 to 1.005 is what I aim for (I'm at work, it is home so check that figure)... so if you buy one, make sure it reads that low... the ones with the swing arms don't, but most that float do.
