Can you change your water to often?

[Coral Newbie]

Was wondering what everyone’s thoughts were on more then one water change a week? Is it bad to change the water more then 1 once a week?

Thanks

Like so many things, it depends on what's going on in the tank and what you're doing.

Feeding heavy? No prob , ULNS, could be probs. Etc.

I just whent through an issue with changing my water without bacteria I only have a 20 gal but u also need to think about replacing that bacteria in the water change

Depends on volume too.
3 5 gallon changes throughout the week on a 120 is more stability than 1 15 gallon change all at once.

I have a 45gal Redsea. And I am changing every 5 days and over 3weeks that’s one extra water change vs a 7 day change. I do about 1ogal because I have a 25gal sump so I’m including that in my total water volume. Not sure if that’s correct or your supposed to just go of off your tank volume

Depends on the why your doing wc too. If your lowering nutints , or helping to keep up on cal alk.

If your unsure ,what I do is weigh the labor , will a 10g wc every other week keep the cal alk where you want it and the nutrients where you want it.

So for me , that's one bucket every other week in both tanks. Even though one is 30gal, and one is a 55 w 65ish vol.
So two buckets up the stairs twice a month. Lol.

It’s for a couple of reasons

1) Keep my Alk up
2) Lower my nitrates with out having to use NOPOX or something like that
3) I purchased the big bucket RedSea Pro Salt instead of there normal RedSea salt because I wasn’t paying attentions and eventually i would like to drop my Alk to 7 instead of the 10.5-11 where it is now. but just tried to do that but I burned my tips out on my Acros i think because my nitrates were to high.

I read that if you have high Alk you need to have higher nitrates and if your running lower Alk then you need lower nitrates.

 

[saltyfilmfolks]

Burned tips are high alk burn. Not nitrates.

Slow your wc regimine , let the alk drop , don't sweat the n/p, they'll prevent the burn. One the alk is around 8, then do the wc.

See then I’m confused because RedSea Pro Salt mixes at Alk 11.5 which they say is good for acro frags and a mix tank which I have

You've decided on an alk level, now it's a matter of balancing the rest to that number.

If that number is higher , you'll need more nutints, it avoids alk burns, if that nimber is lower , you'll need slightly less nutints to avoid browning.

So if you are not dosing , and want to maintain an 8 or so alk, you'll want fewer water changes. Also slightly less Nutrients. You can do that with a Refugium , a larger skimmer or slightly less feedings.

Make sense?

All salt mixes are good for acros. Just acros have more requirements other than salt and alk alone. Acros are the more difficult coral because they uptake all the available nutrients to grow. Sometimes at faster rates than other corals. For that we have to test nutrients and balance them with the basic alk, ca, and magnesium. So if you haven't upped your water testing game, might need to do that to help identify sps issues.
