Axolotl bacterial growth

I’m trying to figure out the best method to get my daughters axolotl healthy…it looks like you have live plants in your tank…I don’t equilibrium might not be the best solution for me. Replenish does look like it has the same characteristics in its ingredients as hertfreters. I’ll start with a quarter cup of salt and if it doesn’t put the salinity to where it is needed to be…then obviously more will be added. I’d rather increase by alittle than dump too much and be screwed!

Astro respectfully disagrees.

I do my calculations purely on percentages of salinity in the water. I took a gallon jug and figured out how much it took to bring it to 5%. Multiplied by the size of tank. Then do teaspoons to cups.

Honestly both ways probably work. Ive just never used holfreters.

when you are measuring solids and powders it is best to be done using weight rather than size, for example 5 grams of sugar is 1.19 tsp where as 5 grams of salt is 0.84 tsp.
1 tsp of salt is 5.92 grams, 1 cup is 48 tsp, so 2.5 cups is 120 tsp, 120 tsp x 5.92 is 710.4 grams, now if the tank is 40 gallon (US) which is 151.4 litres - divide 710.4 by 151.4 = 4.69 grams per litre salt, now most tanks aren't filled to the brim so the actual amount of water is less than 151.4 litres and more nearer to 140 or less making the amount of salt be over 5 grams per litre.
salt in holfreters at 100% is only 3.46 grams per litre, so for 151.4 litre it is 523.84 grams or 88.49 or 1.84 cups

I never used holtfreters either but replenish says it’s specifically to raise gh and then add salt to raise the kh

looking at the instructions 12 - 16 5ml cap fulls are required to get the tank water to moderate to hard gh.
salt is a neutral base and doesn't increase or decrease kh, to increase kh bicarbonate of soda can be added.

I see what you're saying. My only thought is once its dissolved in the water wouldn't the weight be irrelevant? At that point I use a refractometer to get a ppt measurement.

once the salt is dissolved it's weight does become irrelevant but the question still stands that you need to know how much is in there, if for example you came across some saltwater then a refractometer or hydrometer would help to tell you how much is in there where as weighing the water and measuring in cups will not, now if you had freshwater and some salt then the salt could be weighed out and added 5g to one litre (1 litre is one kilo) make water with 5ppt salanity.
to know how to measure by size ie.. tsp, cup etc.. you need to know the size to weight ratio. with salt and most chemicals associated with cooking it is easy to look up, but when you start using chemicals such as potassium and magnesium it become much harder to do so.
so when you have an solutions chemical list measured in grams it is much easier to just continue with the same measurement then alter it and make it a lot more difficult and less accurate.

I ordered the seachem replenish and I’m looking at the instructions too…for 40 gallons it says roughly 4 capfuls…I’m trying to figure out where you are getting the 12-16 cap fulls at?

Sorry for the responses everywhere…I’ll consolidate to one post.

I ordered the Seachem Replenish and wolfen mentioned in a response that I would need 12-16 capfuls but the directions state 4 capfuls? Could I get some clarity on that? Also, it says to add to RO/DI water but I’m using tap water so is that a problem? Any guidance would be greatly appreciated
 
your water is soft and axolotls do best in hard water, as it shows 1-2 5ml cap per 10 gallon for moderately soft, 3-4 for moderately hard water, so for moderate to hard water 12-16 cap fulls are required. yes it is also aimed at ro and distilled and to get the general hardness to about 14° if it was ro/di would require 5 cap fulls.

So I do 12-16 cap fulls of replenish for my 40 gallon tank…now I mixed 2.5 cups of aquarium salt in a 5 gallon bucket and let it dissolve and the salinity is up to 35%. I didn’t add it to the aquarium water yet as it’s just in a 5 gallon bucket but did I do that right?
 
the amount of replenish is correct but I personally wouldn't use that much salt.
 
I just found your post where you suggested 1 cup of salt and then if I do a 50% water change just add 1/2 cup salt or 25% water change 1/4 cup salt.
 
So I put 1 cup of salt in the tank…didn’t register as any salinity…I put one more and still same result! I’m not putting any more in cause I’m not getting any results! Am I doing something wrong?
