Water Changes

[Doug T]

It's been two weeks since my last water change and my water test is good. Should I still do a water change?

yes. What is "good"?

 

[Germ42]

That's a good question, and I'd like to know what can be measured to see if one is necessary! I check ammonia, nitrites and nitrates, and phosphates. I check my alk, Calc, and magnesium, and I dose fuel bi weekly

My thought has always been if my levels are good I shouldn't have to do a water change but I'm far from an expert!

I agree. but, but we have six tests. How many elements are in mixed seawater.
Keep in mind Im the guy who regularly recommends skipping or doing much larger WC when nutrints are low or in fact stripped.

As of now I only can test ph, ammonia,nitrite and nitrate

That's a very good point. I know there are a lot of elements, but what if you were to dose trace elements? I see people saying they haven't done a water change in months and their tank is thriving, just curious how they can accomplish this!

I err on the side of doing too many water changes rather than not enough. In a huge tank, though, that would get very expensive.

most don't I believe. I usually envision a box full of water and rotting food and poop. And yes corals and fish can live in that.

That would be fine. Personally I dont want to be a full time chemist. or keep getting triton tests.

Err on the side of regularity .... just because your tests make you happy doesn't necessarily mean that you couldn't be happier. The fact is that your Reef is ready for a water change .. it expects it. Get it done.

Tuppence. FWIW.

I say yes, do a water change. I do about 10% water changes per week.

Like the meds some of us have to take every day, water changes have a therapeutic effect on the creatures we keep. If you skip it or prolong it, could there be a cumulative build up of nutrients in long term? I stick to my 1x/month WC minimum.

The problem is not only molecules that are used, but also the ones that build up.

Awesome info everyone! Very good points on all! Thanks! [emoji1][emoji38]
