WC and %salt during medication?

Hi,

for prolong medication (eg. months) on daily or alternative days of dosage, are subsequent dosages calculated based on the existing water volume or the vol of WC? [concern: WC only 20%, but if dosage based on existing water vol, won't the concentration increase and be deadly?]
Or is WC necessary during this period?

Is 0.3% salt added in addition to the existing amount of salt concentration in the tank? [eg. existing salt conc already 0.2%, then add another 0.3% = 0.5% in total?]

pls advise. Thanks.

Example. U put 50 spoon of salt (0.3%) to ur tank. After u WC 20%. Just top up 2 spoon lor.

does it mean that when salt is first introduced as treatment, the first amount is always calculated based on the existing water vol, regardless of the salt conc already present? [I have always maintained about 0.1% salt in the tank.]

Yes. Unless u do 100% WC. Or, u do WC for many many time Until the salt is not there. Or else u just top up the different. BTW, there is no need to add salt for nothing.

So if u now add 0.3% salt. Then after treatment, u did not add in any more. The after a few month of WC, 1 day ur aro sick. U wan to add salt again. U will have to add 0.3% salt.

Don't keep adding 0.3% salt after each water change or soon you'll get a salted fish.

Advice noted.
thanks to all.

seeing this made the day!!!

for me i never measure the salt i put in, just based on instict

maybe my aros can be considered salted fish by now

For me, when I do a 20-30% water change, I will calculate the volume of the amount of new or aged water you put in. Then use the tank conversion chart that if found in the main page and calculate how much of salt you need to add based on 0.3% salt.

noted.
based on the feedback so far, i suppose the whole idea is to maintain the concentration. Does this apply to the dosage of medicine put in during WC as well?
