old tank syndrome

[dnsfpl]

my total water volume is app 400l

doing weekly water change(20l, 5%) for the past 2.5 years, using tap water with anti-chlorine

thinking of doing a major water change(100l, 25%), using rodi water

does major water change prevent old tank syndrome?

will major water change bring more harm than good?

thanks

My 450 litres SPS dominated used to do 80-120 litres water change on monthly basis with no ill effect as long as the KH component is observe. I have done 50% water change during tank overhaul, meaning removing all livestocks, rocks and substrate within a day with no casualty 4 years back but then only a handful of SPS.

thanks for your prompt reply

my objective is to reduce accumulation of chloride, heavy metal, etc and also to replenish elements

my main concern is will major water change bring more harm than good?

i have bad experience in doing major water change, maybe due to using tap water

cheers

Can do major water change using NSW, there are still a few LFS providing such services.

Forget your questions, IMO, major water change should not b bad as it allows the chemical properties equilibrium to be brought back closer to natural seawater which we may stew up due to dosing/CR.

nsw is no no for me

any method to make rodi water without rodi unit?

iirc someone make rodi water using pump and di resin

Buy Distilled water loh.

RO/DI or DI water need slow flow to a point of trickling in order to effectively filter tap water. So if you are doing major water change, you will need to prepare few days ahead.

Some distilled water company are happy to sell on ad-hoc basis.

good idea bro

iwarna is able to deliver and supply the DI water at your doorstep at a small cost

Just wanted to address your concerned. IMHE early last year I had done more than 60% total volume of my tank system. Total water change of my DT by NSW and have taken half of the live rock out (that my mistake I think). I discovered my water parameter start to whacked till about more than 6 month things come to stable.<br /><br />As long as you don't loose your content of the colonised bacteria on you live rock even the wall or sand bed of your current existing bio stability then it should be OK.<br /><br />Just my 2 cent.

NSW got its downsides. Some lower Ca, some lower Mg. If your tank is populated with spses, I wouldn't play with NSW as part of overhaul.

Instead I'll prefer going saltmix with distilled water though you might need a few days before hand to prepare. .

Let me know if you need help

[dnsfpl]

thanks bro

manage to get in touch with patrick, 91051231

he charge $36 for 114l of distilled water

will make it an annual event if the result is positive

im concern on my chloride concentration, tap water + cacl2 + mgcl2

time bomb in the making lol

cheers

actually chlorine is fine. If you worry about it, use some seachem prime to renove the chloramine and let your water stand overnight before putting into tank.

Nonetheless it's good to do an overhaul once a while. Resetting the system to prevent overlogging of those deadweight..

saw this @ reef builder.

This guy does a 95% every week? if youre interested you gotta go search thru reef builder
