100% water change with existing livestock

[erikokelf]

Hi bros would like to check if anyone done before 100% water change on existing tank before.

I'm intending to do a 100% water change due to negligence of tank because of official traveling. Currently all parameters are off so I'm thinking of changing 100% one shot for the fastest remedy.

On top of that I'll also add in additional dead rock that I'm cooking for rescaping.

100% water change will come only after rescaping and will slowly acclimatise my fish back.

Not sure if there'll be any issue so would like to seek opinion from bro here who got similar experience thanks.

20-30% daily would be better and healthier for the fishes until good parameters are back.

I tried 100% change before. It didnt end up well for everything.

Everyday 10% would be better bet...

100% water change caused removal of a big mass of beneficial bacterials. Causing the tank to go into cycling mode. I do heard of some people got away with it but most didn't.

1st of all, what make u think of 100% wc aka reset tank? are ur livestock showing distress behavior n look abnormal? If ur livestock are healthy, they can easily adapt to the new water (note that SG dun differ alot) but contradicting is if ur livestock are healthy, why need to wc 100%..if ur live rocks n biofilter are seasoned, 100% wc should b no problem..good luck bro

Thanks for all the suggestion and advice bro.

I'm doing 100% water change because due to the parameter, all my corals have gone now only left with fishes.

Instead of doing graduate water change which will be a tedious process when comes to making RODI water which will be a really slow process. So i'm intending to do 100% water change using NSW for the fastest way to get my tank ready. While ca, mg, alk all can be buffer up gradually.

I actually did thought of reset tank but i got no idea where to host my fishes. Currently have 5 fishes which have been with me for years.

If you wish to restart hold your fishes in a another makeshift tank with a cheap skimmer and water change often. Restart. And cycle the tank wait till all water test are all good and re add

New dead sand

Maybe cure your rocks

Basicly like a new setup

i would go for 100% WC too since all ur corals die out left only fishes.

Yup. That's what I reckon as well. My only concern is only the ill impact that will happen so as to be fully prepared for the worse.

Bro dose bacterial after the wc. It may help a bit
