Question: How Much Calcium Should Be In A Reef Tank?

What is the ideal calcium level in a reef tank?

The ideal range for calcium in a healthy reef aquarium is between 380-450ppm.

Values below 380ppm may slow the growth of corals, whereas high levels of calcium (>500ppm) puts the tank at risk for a decrease in alkalinity, which could impact the overall health and pH of the aquarium..

How often should you feed soft corals?

2 to 3 times a weekWell-Known Member. Depends what it is really but generally 2 to 3 times a week is normal for me.

How do you keep soft corals healthy?

To keep soft corals, you will want to regularly test for nitrates, pH, and salinity. While setting up your tank, you will want to track ammonia and nitrite, in addition to the water parameters listed above.

How much light do soft corals need?

Most Soft corals prefer moderate light in aquariums. They can be placed at the bottom of your tank if you have powerful lights or if you have dimmer lights they can even be placed at the top of your tank. This Aquamedic soft coral dominant tank displays the different colors and textures that can be found.

How do I maintain calcium in my reef tank?

The easiest and most popular way to maintain calcium and alkalinity levels in a reef aquarium is to use balanced 2-part calcium and alkalinity supplements. We recommend 2-part supplements that contain calcium and alkalinity in balanced ratios, along with trace elements.

Will high calcium kill corals?

Having high calcium in our tank water may be dangerous for causing precipitation events, depleting alkalinity and magnesium, decreasing water quality in a big way, but it will not be directly poisonous to your corals.

Does soft coral need calcium?

Signs of Low Calcium Even “soft” corals needs some calcium, since their bodies contain calcium support structures—though they use less than hard coral. Without enough calcium, corals will grow more slowly than they normally do.

Can too much calcium kill fish?

Sudden changes to water chemistry damage fish more than keeping fish outside of their ideal range. However, extreme values and sudden changes can stress and kill aquarium fish. … In extreme cases, too much calcium can kill aquarium organisms.

Can low calcium kill corals?

To my knowledge it does not. There is evidence that calcium levels below 360 ppm may impede coral growth, anything above that there don’t seem to be any deleterious effects.

What does a calcium reactor do for a reef tank?

In marine and reef aquariums, a calcium reactor creates a balance of alkalinity. An acidic solution is produced by injecting carbon dioxide into a chamber with salt water and calcium rich media. The carbon dioxide lowers the pH by producing a solution high in carbonic acid, and dissolves calcium.

Do you need a calcium reactor for reef tank?

Anything under 100 gallons probably does not need a calcium reactor, as most experienced hobbiest either have really big tanks or really tiny, nano tanks. Unless your rock is bathed in sps coral, you do not need a calcium reactor.

Will raising calcium lower alkalinity?

If, for example, you add too much of a calcium supplement, you will drive down alkalinity as you get precipitation of calcium carbonate in the tank. Likewise, adding too much of an alkalinity supplement can result in reduction of calcium.

Is a calcium reactor worth it?

For the average reefer with a normal sized tank and affordable 2-part solution like BRS Bulk Pharma, there isn’t a meaningful return on investment. On the contrary, a calcium reactor can absolutely be a solid financial investment if you are in one of three common situations.

How fast can you raise calcium in reef tank?

The general recommendation is no more than 100 ppm per day, but doing it over two days should be fine.

Can calcium be too high in a reef tank?

Calcium requirements tend to increase in most reef aquariums as they grow and mature. … If calcium levels get too high (over 500), there is a tendency for alkalinity to drop, affecting the buffering capacity of your aquarium water. Without adequate buffering, pH levels become susceptible to fluctuations.

How do I increase calcium in my freshwater tank?

Preferred methods of calcium additives are ground coral, liquid additives, cuttlebones, and eggshells. Owners must be thoughtful in their calcium additions however; if the calcium concentration in the aquarium is too high, then scaling can occur, increasing the frequency at which the filters must be cleaned.
