Post Acclimating guppies / endlers


Here folks is a process to acclimate some guppies / endlers (even MTS) over to marine. I am currently doing this for some MTS, and is currently what I would do for guppies / endlers. It takes about a week doing this way, but the slow method is better from my experiences, and from what I have learned from my research.
You will need
* a gallon jar / container (scale everything if acclimating more than a few fish and using larger container)
* half cup of marine salt mix
* a cup
* a tablespoon measure (the kind in your kitchen for measuring stuff, not what you eat soup with)
* a gallon of clean water (if you use tap water then dechlorinate it of course)

Important point: Half a cup of marine salt mix to a gallon of water brings the salinity to *approximately* 1.023, give or take a bit. There are 16 tablespoons to a cup, thus 8 tablespoons to half a cup.
Fill your jar with the gallon of water (clean, not from tank). Add a fish, to a max of say 3 guppies / endlers (for more fish use a bigger acclimation container & more water & salt). Pour some of the water out of the jar into a cup. Add two level tablespoons of salt mix to it and stir to dissolve completely. Slowly pour about a quarter of your cup into the jar and gently stir up the water. A couple of hours later add another quarter of your cup, then a couple of hours later add another quarter, then another couple hours later add the rest. Leave your fish over night.
Now for the next 6 days follow this step. Pour out some of the water into a cup and add one level tablespoon of salt, then stir to dissolve completely. In the morning pour in half of your cup, then in the evening pour in the rest. Gently stir up the water when adding the salty water. Don't feed them every day. Perhaps just one tiny feeding on day 4, but keep an eye on the water. If you need to change the water for some reason (like you've been feeding them and now have lots of ammonia) then mix up another gallon of water with as many tablespoons of salt you already used, and use that for your water change.
By the end of the week, 7 days, you have added in 8 tablespoons of salt to the gallon of water. Test the SG of the water. It should be in marine range now. Ideally it should be within a point or two of your marine tank's salinity level that you'll be putting in your guppies / endlers.

Acclimating to the tank - Simply pour out a bunch of the water, approx. half, from your jar (into your main marine tank perhaps) and then over a couple of hours keep on adding cups of water from your main marine tank into the jar until it is filled. You may pour out half again & repeat or just plop them into your marine tank by now. It would be kind to bag the and let float in your tank for a while to let the temperature match before you release the fish into your tank.

You now have guppies / endlers in full saltwater. See how Nemo likes them. Beware that huge fish might also like your guppies, but for sinister reasons.
