water top up......salt calculation

[GrooveMeister]

Howdee,

I was just wondering how you guys calculate the amount of salt needed for the water change, so as no to affect the tanks salinity too much?

the idea is to have the new water to have the same salinity with the tank.

initially we will have to use test for the salinity per pail of new water. after several trials, we can just make a marking in the pail and on the cup (that use to scoop the salt). from there on, we can just follow the marking...

steps (for adding in new water):

1) marking on pail (filled with water)

2) scoop salt with cup and add to pail

3) measure the pail (repeat 2 and 3 till we get the ideal SG)

4) mark the cup

5) for every water change, just follow the marking will do.

will need to do the same for the tank/ sump as well.

Hi andtsg,

Thank you for the reply, am i correct to say that if my tank salinity is 1.023, as long as the water in my pail for top up is 1.023 i will be ok?

you are right in the salinity aspect. of course there are other areas that you can ensure that there are the same ie PH, temp, etc. but for me i only ensure that the salinity is the same then pour it...

You can also make sure the Alkalinity (KH) is the same before pouring in... from my experience a lot of salt mixes give very low KH readings... hence it is healthier to fix the KH in the mixing bucket than in the tank

Howdee Guys,

Thank you andtsg and jervismun for the advise.

I am using distilled water and salt mix, do i still have to leave it overnight?

I have a JBJ nano 24 Gal (FOWLR) and i intend to change the water 20% every 4 days, is it too often?

some salt will take a few hours to be completely desloved. there is no harm in airing the water over night as well

how frequent to change water will depend of a lot factors, biolaod, what you feed, etc. you can start with changing every 4 days, then every 5 days and observe, then 6 days and observe...

you shall be able to notice a duration (4days/ 5 days/ 6 days, etc) which is the maximum days that you can do before the next water change. so that shall be the days that you shall perform water change

Thank you so much.
