What would be the right epsom salt dose for a 40g?
As long as they have been dry and didn't get stuck together or clumpy, evidence of too much moisture, you should be alright to use them, if the package could be many years old then time for new ones. The antibiotic effect reduces a small amount, more and more so over the expiration, over time, but if kept dry it retains a useful amount for a few years. If in sunlight or moisture then not good. Older by a year or 2 probably still useful enough to help but fresh ones you know it is stronger potency. So my thinking is 75-85% effacy is better than 0.
Also check in the lfs
for the expiration too, as just because you just bought them doesn't make them fresh (of course being un opened they would be fresh-er
As for the Epsom salt. You might start with the 1 tsp per gallon if you'd like to. I would just start with the 1 Tablespoon per gallon if I were doing it for my fish.
1 tsp p/g so 40 tsp plus the amount you have in your filters, calculated into a cup measurement would be about .85 - .90 Cup of Epsom. (thank you calculating conversion tables).
1TBL p/g is 40 tbl is 2.5 Cups
So how I do it is I dissolve the ES into very hot water in the pitcher or bucket.
When all but a few little crystals remain, its okay of they DO all dissolve, I add cool water so I can get the concentrate to tank/room temp.
TREAT with dechlorinator/conditioner.
Then I add that to a pitcher (empty Gallon water jug works great because it has a top) or other container to add to your pwc
or tank water.
At first I do a pwc
so I don't have to worry about that for a little bit.
Add the concentate for the whole tank you just mixed in increments, say 5 additions of liquid concentrate over the course of 24 hours.
Then in the future additions of the concentrate when you make up a new batch - I try and do a concentrate mix ahead of time so I know I need to add 2 cups of concentrate per 50% pwc
or what ever quantity you want to do. You can add Sharpie lines to the jug/pitcher (water jug/dollar store pitchers) so you only have to do the measuring one time. (In 1 cup or 2 cup increments or 1/4 of jug what ever works for you) It makes the job of adding it so much more convenient to me.
Add the concentrate at the beginning of adding the water when you add the conditioner. I am using bucket pwc
method of adding water to tank so that is how do it. I would add the concentrate after adding water if you use a Python type method.
Then keep that ratio for 2-3 weeks treatment period.
If all seems better then just reduce the ratio down to a tsp p/g for a couple more weeks and then as you do pwc
, just do not add it back in and after a few changes you will be back to just tap water pwc
