Water Changes

[joachimsim]

Hi,

For changing of tank water, May I know how long should I pre-mix salt with water before ITs SAFE for use to change water..for my tank..

Can Kalkwasser be used in Freshwater Tank as well?

Cos my top up water ..I am thinking of filling 2 tanks ..Marine and PLanted at the same time..I think Ca is good for my plants too..

Kalkwasser is Ca OH2 right? So it INcreases GH, KH of water and PH?

I usually pre-mix my saltwater 1 day in advance. So far I do not have any problem. I use dechlorinizator on the water before adding the salt.

For the other question, I dont know.

I do mine 10 mins before. So far no problem. I do not have the luxury of pre mixing too long because tank is in office.

i add the pre-mix saltwater once my powerhead dissolved the salt. not more than 30 mins.

Any idea if DI--What the hack does this stand for? and RO water is Really that good for our tanks...

I think besides heavy metals...NO3 of our tap water is 0 right?? I donno abt the new water we have today..

Here shows the Typical value of Local Water.

Harmony.

I am not sure how to convert the values but surprised that there are NO3 levels of 0.5- 7 mg/l...

I don;t know waht 20-50mg/l Alkalinity...translates to in KH..

Total Hardness Refers to GH??? 50- 100?

From my Sera Test Kits..PH =7 and KH =0 in my area...Never tested the NO3 of my tap water before ..

HOw abt you?

In planted tanks to raise kH you simply use baking soda. That is sodium bicarbonate.

Not Calcium hydroxide! That will raise your pH and everything will suffer.
