Water Changes - everyday, weekely, monthly...

Hey guys, whats best for a mixed reef tank? everyday 1-2% wc or weekely 10% wc or monthly 25% wc? a local reefer in my city changes water weekely 10% using redsea coral pro salt and dosent dose anything else. his hard corals growthrate is slow but there are no die offs. I dont want fast growth too due to the tank size. any further advise? is anyone doing this? iv been changing 5% weekely

 

+1 that's what I do. 10% a week and using Redsea coral pro salt. Don't dose anything else.

 

5% weekly for me at present , also using Red Sea coral pro

all the methods described are acceptable though
some choose to do fortnightly, some choose monthly
and there are a number of people doing smaller water changes on a daily basis
there are also those that do not do any water changes, unless they feel their tank would benefit from it

find a routine that suites you and your own tanks inhabitants and stick with it

kool guys, so ur hard corals are growing??

 

They are, but not so fast that you see it happening nanomania
I can mostly tell, when looking back a couple or months at photos taken
I can also tell when one coral seems to be closer to its neighbour than it used to be
in addition to water changes, I also dose the big 3 - Calcium, Alkalkinity and Magnesium

coralline is my most prolific grower , I can literally see new spots of that growing on a weekly basis

So u do dose supplements..... what if i change 1% water everyday?

 

No issues with that IMO
although its a bit inconvenient and that is the main reason I have elected to go with weekly to be honest

if you have a low demand tank in terms of Calcium and Alkalinity needs, and you find that your tank stays within acceptable reef parameters, on water changes alone then regular/ frequent partial water changes of a smaller volume such as 1% are fine

really depends on your reasons for changing water
if the reason is, to continually replenish the system with elements, that are being used - then smaller , more often is a good way to go
if the reason is - to reduce nutrients, due to water quality issues, then less frequent larger volume water changes would have more benefit IMO

i just added a 1" frag of acro and 1" frag of brain. so if i change 1% water everyday, will it be ok? i have a jungle of halmedia in my sump too.

 

I doubt very much the addition of those 2 corals will have any noticeable effect on your calcium and alkalinity demands
although I would suggest you test and monitor, because as they grow and as you introduce more corals , then there will be a demand and it is monitoring and then reacting to that demand which is key to the growth aspect
