Is it better to change water using saltmix or NSW from the LFS? The trace elements found in slat mixes should be more complete than NSW right? We don't know what the NSW was used for or where it came from and how old it is.

[loster]

it is better to do water change using saltmixed. my water change is 5% weekly

[hondaker]

i change 20% per week with salt mix

to compensate for the lack of sump, high grade skimmer and slight overfeeding

[Elune]

I change water every day! Evaporate very fast.

Change 20% water every 2 days. (its a 1 feet tank, so very easy to change).

[Alvin Tan]

i change 15% in once in 2 wks....using saltmix...more concentrated trace elements rather den NSW...

last time i use tropic marin....now i mix the saltmix using zoomix 85% and

coralife 15%...i take coralife as a booster for calcium and magnesium as i hav done test b4...coralife is more on the high side for calcium...tropic marin salt only using once in a while now..

Got to change water one meh? (joking lah, heard about it after I started the hobby otherwise wouldn't have start at all).

I just started about a month ago, yet to change anything. The tank look great and fishes and LR is great too. I think I will do a 5% change every month for starter. If the quality of the water is right, I think can last longer.

Key to it, don't over feed but to feed many times as little as possible? LS less LR more. Add more crabs and shrimps.

Not sure my theory works????

[chrislwp]

Just changed today, about 25%.

My last water change was Nov05...

[Guinness]

Oh dear, u guys (and gals) are making me feel guilty.

I am one of the 'once in 3 months' group.

But then I think another factor to take in is the size of tank. And also the inhabitants of the tank.

My 5' x 2' x 2.5' is 1x in 3 months. Been surviving well for erm.... cannot remember how long liao. FOWLR + a few commando corals.

I have a smaller 2' x 1.5' which requires more frequent changes. About 1x per month.
