How Often Do you Change Waters?

[raymus]

bro. just to ask.

most reefer change their water from de main tank or sump tank?

i siphon water from sump tank.

btw, i re-filled the distill empty bottles from the sump, and so that i get equal amount of mixed water to goes in.

[andolasoft]

i mine once a week changing the water. They are very sensitive to survive in aquarium.

Hi all, I do not have any sump so change from the main tank, btw where do you guys siphon out the water from?

I just siphon it out from the surface, is it the same?

The last time I change water was 4 months ago

most syphon from main tank and if barebottom they remove the detritus too. if you siphone from surface the air may go inside the tube but i guess it shouldnt matter much. u siphon at same time remove those leftover food etc. some change evry week, some once two weeks some 20% end month..some nvr change and swear by their tank still survives. which ever works. but i prefer 20% end month.lol

used to change 100l per month

now i change 25l(1 pail) a week

a lot less work and keeps the water parameter stable

cheers

Is there any adverse effect if I change water of

10% every 3 days?

[finind]

i do mine once a week changing about 30%.. just a small tank so is not a pain in the back. waste water is recycle to clean equipments n toilet!! great for removing the brown stuff tat sticks on the wall.

wow wonder how small is your tank

if i change 30% weekly with distilled water really will broke!

[Bulldozer]

I did not do water change BUT my water is changed once every 2 weeks.

Have been doing that for the past 1 year.

Out of so many votes i see that 32 people never change water at all.

Any of the 32 Sifu(s) out there, care to share what are the additives you use to maintain your tank?

changing water every week is a very tiring thing for me, especially when commitment are getting more and more.

[s0n1c87]

I normally WC every month 20%. other than that. I clean my filter flossing every wk.

[John Deroe Kenedy]

Since upgraded to 3ft tank. I do water change of 20% every 1 month. Kinda of troublesome to do weekly water change due to tank height + cabinet is 5ft high, no access to RO/DI system. But i regularly clean my skimmer, change filter socks. And Since i'm using Prodibio Digest, I'm able to keep Nitrate level very low.. 2.5ppm ever since i started using it...

[iczboi]

I do water change whenever I feed them.

[tropic]

I do water change whenever I feed them.

Wow. Very diligent... After every feed?How big is your tank and how often you feed?

[John Deroe Kenedy]

Every water change after feed? 3 times feed a day = 3 water change a day? lol

[bkburger]

FOWLR one and a half year never change water

[KELVINx3]

change every week 1 pail - 2pails depends on my mood LOL, mixed fresh salt water will go in sump. draw water from DT and if possible i will clear sand bed a little bit by bit. prevent all po4 to fly up sky high.

haha, I only feed them once a day.

[John Deroe Kenedy]

Got a QNS tho.. Is there a need to change water twice a month even if Nitrite level seems low... I'm able to get 2.5ppm of nitrite full month, po4 is low due to reactor + rowaphos... Its tedious for me to change water weekly or bi weekly coz cabinet is 2.5ft tall, tank is 2.5 feet tall + additional hood... My monthly water change is set on 18th every month.. filter sock change every 3 days.. Prodibio digest added evey 2 weeks..

The purpose of water change is more then just reducing nutrient, it also replace the element and other stuff used up by the coral. Unless u are dosing element into the water every now and then, the element will be used up. For Lps tank, the observation is not so obvious but for sps tank it is quite obvious.

Guys good to read more and not just follow reefer advice. Every reefer tank is different so what he/she do might not be suitable to your tank. One of the example is a reefer tell me he is told by another reefer, only need to change water every 6mth and the tank is doing well but why his tank is not doing well. The reefer that told him this method is keeping softies and Lps tank, while this newbie here is trying to go for full sps.

To add on, those elements that we dose are major elements, but there are many trace elements that are not easy to detect/measure that will be refilled by water changes.

[John Deroe Kenedy]

ahhh.. in that case need to change routine for 2 weeks once... here come my pocket with a big hole..

[patricklhc]

I started my tank about 2-3mths now. Never really did any wc until today. My anemone used to open up nicely and nice translucent pink. Until a few days ago it start to open up only a little and dark pink show up. So did a water change and now it's opening up nicely again and the pinkish tip is back too.. I do weekly dosing of kh buffer mag cal iodine strontium and trace element all from reef max

I guess no matter what I dose wc is still a important task to replace any unknown to me element to keep the livestock happy

[stevenchia]

I did a 50% water change using saltmix weekly with no dosing.. Sounds crazy.. but it works.

[tropic]

20%, 50%, 80%,90%... When your tank water is in large amount , it's always troublesome to change weekly.

[John Deroe Kenedy]

Big regular water change isnt cost effective for big tanks...

for low demand tank, yes, regular water change is effective, maybe about 10%-20% water change..

but for mid - high demand tank, u need to do more volume of water change to replenish the elements which i think its really not cost effective.

Even for mid-high demands tank, weekly water change of 10%, it still not enough to replenish the lost elements.

i rather do manual dosing.. very much affordable as im dosing Randy's 2 part solution and trace elements...
