A h2o change is an deed of removing dirty h2o from your aquarium and replacing information technology with clean water. Water changes are a regular chore in the aquarium hobby while there is plenty of debate as to how frequently and how much should be replaced and there are even methods and some hobbyist who do non practice water changes. Nosotros volition go over what you lot need to know and so that y'all can discover out what works best for you and your aquarium.

The three main reasons to do a water change:

Remove some of the pollutants in the tank due to an issue
Dilute the pollutants and replace with clean h2o for regular maintenance
Replace the minerals or elements utilized by the tank. There is no need for "supplements" if you are performing frequent water changes. This may be all that is needed for smaller tanks, larger tanks may likewise demand to be supplemented with Alkalinity, Calcium, and Magnesium can easily be added and tested for at home.

How oft should the aquarium water be inverse?

This is a tough question to answer because everyone's situation is unique. The only way to know for sure is to test your water. Ideally, y'all want to make sure that the water changes keep your water parameters at a safe level. Allow'southward say you are aiming for once a month if on the third week y'all find your nitrates climbing, the one time a month routine is not going to work for you lot.

Some people feed heavily or have messy eaters and not enough media to grow good bacteria to offset the amount of waste being produced. These users will have to do water changes more than frequently. Test your water levels. You lot do not desire any traces of Ammonia in your h2o or Nitrites both of these are mortiferous to fish. Nitrates (not to be confused with Nitrites) while hints are not fatal to your fish, elevated levels will cause algae to abound in your tank. High levels tin crusade your fish to experience problems.

It seems like the more common options are to do water inverse either weekly or bi-weekly (every 2 weeks). Some of the about successful saltwater aquariums I accept seen do three smaller water changes per week.

How much water should I alter in my aquarium?

It depends, what are your electric current water parameters? Are y'all do a maintenance water change or are you lot dealing with a trouble?

Maintenance

Mutual amounts if y'all practice weekly water changes to exercise 10% water volume and if you practice bi-weekly then 20% water changes. The people who do multiple h2o changes a week commonly do smaller amounts 2-5% water changes each time.

When it comes to maintenance, why would people do multiple water changes a week do improve than someone who does water changes every ii weeks when in essence they are changing the same corporeality of water? In aquariums, it's all about being consequent the more consistent the water is, the better the species in the tank will exist. And so by doing a small water change, the water parameter change is a small amount each fourth dimension. When y'all change xx% of the h2o it causes a significant swing in water parameters. While 99% of the time the change will not kill anything in your tank, most of the time it will irritate species in the tank. Past the time they showtime to become over information technology, information technology won't be long before its fourth dimension for the side by side water change.

Dealing with a trouble

So you are dealing with a problem, permit'due south say your Nitrate levels are 10 ppm and you want them to be five ppm or lower. If the test claims they are currently 10 ppm then you would have to exercise a 50% water change in your tank to get them down to 5 ppm. I usually do not recommend changing more than than l% at a fourth dimension. You can change more than, and it's not similar dealing with a new tank, because bacteria is already established. And then why do I not recommend it? Because irresolute 50% of your h2o will crusade a significant swing in your water parameters which tin cause the species in your tank to freakout. You may think that the sudden change may be a expert thing but they could already be weak from dealing with the water conditions and then a sudden change like that could stress them out further.

If you need to exercise more than 50% water modify to get your water parameters in bank check, and so I propose doing multiple water changes. Peradventure do a 50% water change if you call up the species are dying or could dice. Then await 2 or 3 days and practise a 25% water change and continue doing 25% water changes almost every iii days until you reach your desired goal.

No h2o changes needed

And so there are multiple methods for avoiding doing water changes in your aquarium. Permit's say you lot are dealing with an ammonia spike (super deadly) they only salubrious amount is 0 ppm so what do you lot do a 100% water change? You could get with a 50% modify and continue to follow upward with 25% water changes, just in that location are chemicals to help remove ammonia such as AmQuel.

I think this sparked a whole new fashion of dealing with aquariums. Triton helped revolutionize this motility with their ICP examination to analyze your aquarium water. An ICP examination can test more elements than you tin can at home today. The process is to transport in a water sample to exist ICP tested and they will provide the results and tell you lot what elements are off in your tank. They even take their chemicals to conform your tank and assistance become them back to the correct level.

This is peachy, and if you live somewhere where water is express, very expensive or y'all feel like you are wasting water, then you may want to check this method out.

Sounds great correct, no more than water changes, Aye! Who would not want that? The downside is that everything can add up apace. The Triton ICP test is most $45-450 per exam (not including shipping cost) and then you take the additives needed to make corrections, prices vary depending on what y'all demand. Some people do ICP test every month, so simply the ICP test alone volition cost yous $l a month. Then there are the additives, they sell most of them, simply in some cases when the examination comes dorsum the proposition is to do a water change. Then don't throw away your siphon and buckets just yet, y'all may have to practise the occasional water modify still.

But await, there are hobbyist out there who do not do water changes, and they do non do any fancy ICP test. Well, this is not an overnight process, but a saltwater aquarium can become somewhat self-sufficient as it matures. With that said simply a express corporeality of fish and coral species can live like this. You lot will exist looking for hardy fish and corals that prefer dirty-er waters like zoanthids, polys, and several soft corals.

The no water changes is something that you lot somewhen get to, you tin't start the tank this way. You may need to do weekly h2o changes for 3-4 months and then go to bi-weekly water changes for 3-4 months so a single water change a calendar month for six-8 months. During this process, you have to monitor the h2o parameters and more than importantly, the species in the tank, brand sure you lot are not feeding to heavy. There is no guarantee, but this is how I would go well-nigh it. You will still demand to meridian off the tank but with an auto topper (ATO) and depending on the size of your ATO reservoir it could mean filling it in one case a week, to once a month or never if you hook it up to your RO/DI unit to it.

Keeping Water Not Fish

I do not know who said it first, but you will hear information technology multiple fourth dimension from many people. In the aquarium hobby, you practice non go on fish, corals or plants. You proceed water, and proper water parameters allow you lot to go on other things such every bit fish, corals, and plants. A ill fish heals quicker and more natural in proficient healthy h2o.

With that said having a TDS meter to make up one's mind how much Full Dissolved Solids are in your water. This is nice to have. You may be surprised at the reading of the water yous drink from the tap or even some of the water you lot buy from the store. After getting a TDS meter, yous may detect out that you lot need a Reverse Osmosis (RO) Unit or even a Opposite Osmosis Deionization (RO/DI) Unit to help get your TDS down to 0. This is especially important if you plan to have a Saltwater Aquarium. On freshwater aquariums, you are more often than not worried about how the water is treated and removing chlorine and other chemicals used to treat your h2o. There are many chemicals that you can buy to brand the water safe for freshwater species.

So why is information technology essential that a TDS meter reads 0 TDS for a saltwater aquarium, can't I treat the h2o the same way as a freshwater tank? Unfortunately no. A TDS meter will tell us there is something in the water simply it does not know what in it. In some cases it could be something that does non matter in other cases it could be something like copper and every water change keeps keeps adding simply a lilliputian more to the tank. Eventually killing species in your tank.

I take never personally seen an issue with it continues to add copper to the tank and killing off species in the tank simply information technology could. What I accept seen in every case when someone uses water with elevated TDS levels ( >0 ), eventually they start to have algae issue, and the test do non show anything is wrong. They change their filters practice tons of h2o changes find a fashion to become the algae out of the tank, and they are good again.

Brand It Easy

The water irresolute process is not complicated but it takes fourth dimension, and people are lazy. Some people are lazier than others, and eventually, you will skip a water change for whatever reason. You will discover that your aquarium did not implode for missing a unmarried water change. This is a glace gradient, in one case y'all realize this, it becomes eaiser to miss the next water changes in the time to come. At some point you lot volition miss two water changes in a row, life happens. The upshot is if you miss one water alter, your water parameters are slightly elevated and volition remain loftier until you do an extra water change.

The more water changes you miss, the more they elevate and eventually yous take an effect.

So make the water modify procedure every bit uncomplicated every bit possible or if possible fifty-fifty try to automate the water change. In that location are devices out there that can aid with the procedure of automating the water changes, but unfortunately, about of them are expensive.

If you take a small tank nano making it easy does not have to hateful to automate them. I have a thirty-gallon nano tank twice a calendar week I practice a ane-gallon water change on information technology. I made the process simple. I bought a 1-gallon plastic bullpen, I dip the pitcher into the tank and pull out i gallon of water, I dump information technology, I then make full the pitcher back up with new saltwater and dump information technology in. If My saltwater is already mixed and gear up to become the process takes me about two-3 min — no siphons or buckets.

Bottom line, the easier you make the process, the less likely you lot are to miss a water change.
