Features

  • Eliminates reactive phosphate immediately upon addition to aquarium
  • Safe for all inhabitants of reef and marine fish-only aquaria; May be used on an ongoing basis to help control phosphate in heavily-stocked aquaria
  • Each ml eliminates 1 ppm phosphate in 4 US-gallons of water
  • Helps facilitate phosphate removal during periods when dissolved organic material is abundant
  • Formulated by a marine scientist; Made in the USA

Description

Phosphate, while required in miniscule amounts by living organisms for proper functioning, can indirectly negatively impact the overall appearance of an aquarium system if it is allowed to exist at a concentration measurable by most aquarium test kits (e.g. >0.05 ppm); in order for this impact to occur, other undesirable substances must be present in varying concentrations, however these substances are rarely limiting in the typical marine aquarium. Because of this, elevated phosphate concentrations, whether sporadic or chronic, should be combated. Phosphāt-E enables a quick solution to elevated phosphate concentrations by binding the reactive (“free”) form of the molecule and making it unavailable for biological uptake. The resultant inert phosphate compound (a particulate) may then be permanently removed from the system via mechanical filtration and/or protein skimming. This method of treatment may be used as needed and/or on a continual basis to maintain an immeasurable phosphate concentration in a marine aquarium. While Phosphāt-E provides a workable solution to potential phosphate-related problems, it should not be seen as an alternative to proper and sensible aquarium husbandry. Aquaria with extremely-low to immeasurable reactive phosphate often appear more pristine than those in which phosphate is allowed to persist in an elevated concentration. Feeding aquarium inhabitants sensibly, limiting the use of organic-based supplements and additives, use of a high-quality synthetic aquarium salt blend, and performing water changes/replacing evaporation with purified water are all important aspects of phosphate control. Additional means of limiting phosphate are maintaining a culture of macroalgae in the system to naturally deplete phosphate and other substances, and/or the use of an effective and well-maintained protein skimmer. Note: Phosphate test kits may show a false-positive reading after aquarium has been treated; this is a result of the chemical mechanism by which phosphate test kits operate and does not indicate that the product has failed to perform its intended function. The higher the percentage of bound phosphate removed by filtration, the more accurate test kit readings will be.

Directions: Aquarium may become slightly cloudy when product is first applied; cloudiness is temporary and will dissipate. Basic Determine phosphate concentration in aquarium prior to first use by testing with an accurate test kit. Add product to aquarium near a mechanical filter or protein skimmer intake at the maximum rate of 5 ml (1 capful) per 20 US-gallons daily for each 1 ppm of phosphate present in system. When used in this fashion, 250 ml treats up to 1,000 US-gallons (3,785 L). Add weekly at same dosage to maintain an immeasurable reactive phosphate concentration. Advanced Determine phosphate concentration in aquarium prior to first use by testing with an accurate test kit. Each ml of Brightwell Aquatics Phosphāt-E will eliminate 1 ppm of reactive (available) phosphate in 4 US-gallons (15.142 L) of water. The result is an inert particulate that is permanently removed from the aquarium via mechanical filtration and protein skimming. To maximize the rate of phosphate removal, Phosphāt-E should be added to the aquarium near the intake of a mechanical filter or protein skimmer. Doing so will enable the inert particulate phosphate compound to be effectively removed from the aquarium. Particulate material not removed by filtration will remain inert and the bound phosphate non-reactive indefinitely under normal aquarium conditions. The maximum dosage should not exceed 1 ml per 4 US-gallons (15.142 L) daily, as too rapid a decrease in the concentration of phosphate may irritate sensitive corals, particularly if the phosphate concentration has existed at a relatively-high level for an extended period of time (e.g. 3 - 6 weeks). The concentration of available phosphate in marine aquaria should not be allowed to exceed 0.05 ppm for any lengthy period of time; available phosphate in the presence of other substances can indirectly negatively impact the appearance of an otherwise beautiful marine aquarium. If corals or other invertebrates appear to react negatively to the addition of the product, it may be an indication that reactive phosphate is being removed too aggressively; decrease dosage by 50% and continue treatment until phosphate concentration appears to be immeasurable. Caution Harmful if swallowed. May cause eye or skin irritation. If in eyes, flush with water for 15 minutes, get medical attention. If on skin, wash thoroughly with water. Keep out of reach of children. Not for human consumption.

  • It really pulls down the PO4. I use 1ml per 50g every day until level is good
Size: 125-ml
Works amazingly well. 1ml per 50g per day every day until you get to your desired number. Then back off to every 3rd or 4th day to maintain. I really love this stuff. Excellent buy!

  • Easy and affordably brings down phosphates.
Size: 125-ml
I've struggling with phosphates for awhile now and did all the things, aggressive water changes, all sorts of filtering and feeding changes etc. This stuff had me back to near zero in no time and suddenly corals are growing again. Well I shouldn't say no time, I had no change after the first several days, then it dropped dramatically to not measurable very quickly. As far as I can tell there's no downside. ... show more

  • Dosing instructions are confusing
Size: 250-ML
This stuff might be great, I can’t tell yet, but I have a real issue with the dosing instructions. First, I understand the dose is based on the amount of desired phosphate reduction in a given volume of water. I get that. But you have to do the math to figure out the correct dose. “Each ml eliminates 1ppm phosphate in 4 gallons of water.” Ok, I have 40 net gallons of water in my tank and I want to reduce my phosphate by 0.2ppm. What’s my dose? I have to do math to figure that out. I don’t want to do math. I want to read a chart that did the math for me. Nope. They don’t provide one, not even on the web page. Still, I can do the math to figure out my dose. 1 ml will remove 1 ppm in 4 gallons of water. So... 1 ml will remove 0.5 ppm in 8 gallons 1 ml will remove 0.25 ppm in 16 gallons 1 ml will remove 0.125 ppm in 32 gallons 1 capful (5 ml) will remove 0.6 ppm in 32 gallons. Here’s where my dosing goes south on me. The directions on the bottle also say 5 ml will remove 1ppm in 40 gallons of water. How can 5ml remove .6 ppm in 32 gallons and 1.0 ppm in 40 gallons? If only that had a, what’s it called, oh yeah, A CHART! ***two treatments later*** I still don’t like the instructions and all my earlier complaints about determining the correct amount of liquid to use but...the stuff worked. Like, totally worked. According to my API phosphate test my levels have gone from >1.0 ppm to unmeasurable. Nothing’s died in the tank and I’m happy with the outcome. ... show more

  • Works great

Like many I had a problem with phosphates in my reef tank. So far this is the only thing I have tried that has actually lowered my PO4. I have a variety of fish, shrimp, snails and corals. Not one showed any signs of stress. My advice is to use a lower dosage than what is recommended. Take it slow. Like everyone says you need to be patient with a reef aquarium. You rush anything and you run the risk of a total disaster. Brightwell Phosphate works great. I'd definitely would recommend it. ... show more

  • Gets the job done

We don't have fancy tank, so I pour this directly into the water and do a water change a day or two after. So far nobody is mad and it gets the phosphate down quickly and safely.
