Unfortunately, it is often present in excess in reef aquaria, and that excess has the potential to cause at least two substantial problems for reefkeepers. Ammonia, nitrite, nitrate, pH, phosphate, silicate, chlorine, and water hardness. Understanding how it works in a reef aquarium will help you grow beautiful corals and keep a pristine tank. Phosphates negatively affect your aquarium by acting as fertilizer to pest algae species and promoting their growth which can lead to outbreaks. This is where it allows the liquid binding agent and its attached phosphate compound to come out of dissolved form and become a solid, at which point your protein skimmer and filtration media will collect it ready for removal by you. Maintenance of calcium levels that are at or near seawater values is an important factor in having a healthy reef aquarium. The other aspects associated with a water change are vacuuming the sand bed to remove uneaten food, decaying matter, and detritus and scraping your glass. For Fish-Only aquariums a maximum of 0.50ppm By advertising and linking to these websites TheBeginnersReef.com is compensated for referring traffic and business to these companies and it helps to pay for the running costs of this website.

Be advised that you will need SOME phosphate in your aquarium to be used by your corals to grow, so going overboard and completely stripping your water of phosphate will have the same effect of slow coral growth as having too much! Phosphates are a primary nutrient source for many forms of algae, particularly green hair species, so when high concentrations are allowed to accumulate in an aquarium, it opens the door for aggressive algae blooms to occur. The Hanna checkers use a combination of an Ascorbic Acid, an LED light source and a Silicon Light Detector to provide you with a simple, accurate and easy to use tester. The nitrate and phosphate in the tank is simply being consumed immediately as it becomes available. United States Environmental Protection Agency, 2020. What is surprising to many folks, however, is how large that number is relative to typical target levels of phosphate in reef aquaria, which might be something like 0.03 ppm or less. Often your test results will show phosphate levels are within acceptable levels – because the algae is using the high phosphate concentration up as fast as it is added to the water! You can also prevent calcium depletion in your saltwater aquarium, and the pH fluctuations associated with low calcium levels, by using a calcium reactor. Freshwater & Saltwater Aquarium Forum > Freshwater Aquarium / Fish Tank Forums > Freshwater Aquariums - General Discussion > Acceptable Nitrate Levels. When a coral like Acropora or Torches, for instance, wish to build their skeletons they consume calcium carbonate from the water as one of the main building blocks. But in heavily stocked tanks with strong lighting and a light fish load, it is actually quite easy to end up with a nutrient deficiency of some kind, whether moderate or severe.

Phosphate contributes to the undesirable growth of algae and in high concentrations can negatively affect the health of invertebrates. Even at its natural levels, it can spell trouble. Luckily for us, we can use algae’s love for phosphates to our advantage by growing and disposing of algae in a Refugium or Algae Turf Scrubber. Most freshwater aquarium tropical fish do best at a pH of 6.8 to 7.6, although certain fish may require higher or lower levels. The imprinted scale you see within the device will be horizontally divided into a blue field and a white field. Most reef aquarists try to maintain approximately natural levels of calcium in their aquaria (~420 ppm). This product also absorbs the Phosphate compound and binds it to the Aluminum Oxide, but rapidly. The normal PO4 level in the ocean is 0.07 ppm (remember this number for future reference). Growing Macro-Algae in a Refugium and then physically removing half the mass as it grows instantly removes the phosphate that is bound up in the algae. Of course, an excellent way to start is by using water purified through reverse osmosis (RO), and then using it for regular water changes. Each Checker measures to a specific range of Phosphate. A correctly sized, clean and efficiently working protein skimmer is another great way to help keep Phosphates low.

Planted tanks have the advantage that plants are capable of storing and consuming phosphates. Phosphate (PO4) – common sources for phosphate in an aquarium include tap water, fish food, certain types of activated carbon, decaying organic material, and certain types of buffers and water additives. Once phosphate begins to reach levels above 0.05ppm is begins to inhibit the precipitation of calcium carbonate from the water. For example, phosphates are sometimes added to tap water to protect the pipes, or demineralization systems may use phosphate salts for regeneration purposes, leaving phosphates in tap water.Even when using rainwater, phosphates can get into the aquarium.

I'd recommend phosphate testing to anyone with an algae problem who uses tap water, in order to ascertain whether phosphate in the water is an issue. Waste, as we know, breaks down and releases the phosphate bound up within it. Just as waste and detritus above, any uneaten food begins to break down and it releases its trapped phosphates into the water. Reef Tank Phosphates are best controlled using high-quality filtered water, reduced feeding & fish stocking, regular maintenance & detritus removal, and even some chemical removal products. Phosphate should be kept under 0.50ppm for fish only, 0.05ppm for LPS & Soft corals, and 0.03ppm for SPS corals. Saltwater aquarium fish can put up with higher levels of nitrates compared to corals and many other invertebrates, so for a fish-only system, an acceptable level of nitrate content would be a maximum of 10 PPM (parts per million). This is a product very popular for long-term Phosphate control. Harvesting 10 grams (dry weight) of this macroalgae from an aquarium would be the equivalent of removing 24 mg of phosphate from the water column. To reduce or eliminate phosphate already present, commercial phosphate removers can be effective. The signs of high phosphate levels can be obvious (if you know what to look for), or might be a bit more subtle and hard to recognize. Generally the measurable aquarium phosphate level should be below 0.05 ppm. By using unfiltered tap water for making up sea salt mixes or as top-off water. Not only do the algae blooms look hideous and can be a major battle to overcome they can smother coral to the point of death. Share with: Link: Copy link.
