% of water change weekly/biweekly

[fnscasey]

For general maintenance, is it better to change 5% of water weekly or 15% every two weeks ?

Anyone care to share ?

[lightningstrike]

for me, about 10 to 20% biweekly.

[Clownfish]

it wld be betta if u r considering 10% weekly n 15~20% biweekly..

personally, i'm doing the biweekly routine

[damsel-in-distress]

If I am not mistaken, I think you guys meant to say, bi-monthly (every 2 weeks) instead of bi-weekly (twice a week). These are American terms. I also do 10% fortnightly (UK term) water changes.

we need to do water change as in..........throw out half the salt water in my tank?and add another new salt water in?issit like that?

[[P]owder Blue]

should be throwing out 10 - 20% instead of half the tank.

[skimdude]

if da water evaporates........do i still need to throw 10-20% of the water?

[[P]owder Blue]

Water is to be added on a daily basis, so you do not need to add water during water changes.

The organic impurities gets more concentrated as the water evaporates. So it is good to replace the water. I change mine 15-20% weekly.

thanks alot bro..........now i understand much better.........erm..1 more thing......erm.......i throw out 10-20% of the water in my tank........and prepare a new salt water and add in my tank rite?

[RockyBoy]

Yep... and newer water, the salt content is lesser by 1 pt .... or whatever it is to make the final total tank volume to your desired salinity level.

Top up: use fresh water wth de-chlorinator

Saltmix: use fresh water, bubble it for 24hrs, add de-chlorinator, salt, stir till salt dissolved.

dont need de-chlorinator if u bubble it for 24hrs. there will be absolute ZERO chlorine as a result.

dechlorinator is to remove chloromine too... which cannot be vapourised as like chlorine

[fnscasey]

Considering to switch from changing 15% of water every 2 weeks to 5% every week.

When do u guys check the CA and ALK level ? After a water change to do a baseline testing before dosing any chemical additives?

Seem like the Seachem Prime is a good choice for dechlorinator, remove chloromine and toxin substances.

Dosing 1ML for every 40L !!
