doing water change after cycling

[bomber]

Hi.would like to know after i cycled my tank for a month, my nitrate is at 20ppm currently. so i need to do a water change from 20% to 50% right? Is it okay if i use NSW instead of saltmix? i saw a few posts that reefers use NSW for their weekly water change. so i'm wonder if its okay to use NSW for it as i'm afraid after using NSW, instead of bring the nitrate down, i bring it higher. I'm using a 3ft X 2.5 X 2 tank.

thanks in advance for any kind advice.

NSW is ok, if you are concern about nitrate, do a parameter check before the water change ?

Iwarna do home delivery if u need larger qty of nsw

[kraken]

pls bear in mind the salinity of NSW, its lower than what most reefers keep their tank salinity.

After I brought NSW from a farm in the west, I change 20% of my tank with that and after changing it, one of my sebae clown eye swollen:(I have a 3ft tank and there is only a pair of sebae clown...

No luck with NSW...I guess I better stick back to Saltmix...

Anyway..thanks guys for sharing:)

[kraken]

did u increase the salinity of the NSW before to introduce into your tank?

Should be a case of low salinity. please check

[bomber]

hmm. i didnt increase the salinity of the NSW. i change 20% straight away after the clown eye got swollen with distilled water and saltmix. now getting better but eye still swollen. hope he will get well soon. thanks KRAKEN for the info that NSW had lower salinity. learned something new

a case of salinity shock for your fishes. Sorry if I have confused you, NSW is usually higher than what reefers keep their tank salinity.

I keep mine at 1.025, whereas NSW is usually 1.026 - 1.03, depending on the condition it was harvest, if it had rained day before, the salinity would be lower.

in any case, one should exert caution and prudence when using NSW, always check the salinity since its not contant.

oh. but do you guys check the nitrate and all for NSW before WC? if its high in nitrate and all, do you guys still change it?

[kraken]

if you want to introduce more nitrate into your tank, then go ahead.

Hi bro, care to share which LFS NSW gives you that high salinity reading? i understand that most lfs have much lower salinity reading, on an average of 1.017 to 1.020.

i personally dont do that check, but it is good to check it first.

when i am doing water change to remove no3 po4 etc, i usually go for salt mix, safer that way.

yea better check before it enter your tank
