Magnavore (PURA)

Groundbreaking filtration media at the right price. For Reef, Marine, Planted, and Fresh Water aquaria!

The PURA family of filtration media is formulated to reduce scum formation in fresh and marine aquaria.

All PURA products are formulated with Beta-GFH (Beta Ferric Oxide Hydroxide), the groundbreaking German made phosphate removing media that eliminates the primary nutrient of aquarium scum. PURA filtration products lead to a much cleaner and less labor-intensive aquarium, good for the animals, good for the hobbyist, good for customer retention.

Hydrated Beta-GFH is vastly superior to white colored Alumina based phosphate removers and greatly superior to numerous Alpha-Ferric Hydroxides sold in dry form.

PURA PhosLock removes 45% more phosphates than Alumina media, and 20% more than Alpha-Ferric Hydroxides. Unlike Alumina, PhosLock never leaches phosphates back to the aquarium. Unlike competing Alpha-Ferric Hydroxides, PhosLock never disintegrates and never turns soft and muddy in aquarium water. PhosLock comes fully activated right out of the jar. PhosLock does not need a specialized reactor and can be easily confined and implemented in a fine meshed media bag.

PURA PhosLock
Professional Strength Phosphate Remover


PURA PhosLock is 100% pure Beta-GFH and will keep phosphate levels at 0 ppm, a highly desirable level in reef, planted, and exhibit quality aquaria. This is the most cost effective phosphate remover in the market place and unlike dry phosphate removers, PhosLock does not turn to mush in an aquarium. PhosLock outperforms all competing products. Packed hydrated with an induction welded foil seal for freshness, protection, and long shelf life.

PhosLock is the benchmark German made ferric hydroxide media for total phosphate removal in all aquaria. Used all over the world, it is the product of choice for many critical water purity applications. PhosLock permanently binds phosphates. With regular use of PhosLock any aquarium fresh or salt, reef or planted, will stay much cleaner and less maintenance labor intensive! Media bag with PhosLock can be placed inside of: canister filters, power filters, pond filters, sumps, refugiums, corner filters, next to uplift tube on UG filter plate. PhosLock can be placed directly into Bio-Bags or other fine floss bags. PhosLock is 5 to 10 times more effective than white activated alumna media and it is completely safe for fish and invertebrate, fresh and salt-water aquariums.

Very Poor Product

At first I was mystified as to why this product was getting 5 stars. After reading a few I realized most folks were using GFO for the first time & were overjoyed to see results with their algae problems. Yes, Pura Phospock works as do all the other major brands. I've used a bunch of different brands & this is by far the worst. I bought the 150 gram package. I didn't weigh it but the volume was exactly one half of the same 150 gram package of Two Little Fishies Phosban product! Very evident looking at the reactor. Got out a magnification glass & say irregular granual size. It does not "dance' properly like other products. The worse thing is the DUST! The TLF Phosban rinses clean with very little water. I used 4 gallons of RODI water rinsing & it still ran red. Unacceptable for a premium priced product! The only good thing is they include a very nice Velcro media bag which I don't use for GFO but will use for carbon. Don't be impressed with this "German made alpha ferric oxide" marketing jibber jabber. That's all marketing hype IMO. THE STUFF DOES WORK BUT THERE ARE BETTER PRODUCTS ON THE MARKET. I must say their other products have performed very well for me but this was a big disappointment.

So far, so good

I have used this product now for about 2 weeks and so far, I have noticed almost undetectable phosphate levels. I have tried many other items up until now. It comes with its own media bag and I just added it to my sump. It doesn't leach the phosphates back into the system like some other products do. My corals also seem to like it.

Eliminates hair algae

Had been battling severe hair algae in my planted aquarium for almost two months. Tried all sorts of remedies recommended by others in forums and such. Phosphate level was 0.09ppm, the rest of the tank chemistry was nominal. Finally bought the small bottle of Pura PhosLock to give it a try and put three tablespoons in a fine meshed media bag of the filter for my 33 gallon tank. In a week the hair algae was reduced and in 3 weeks it was gone. The product is put in a cloth media bag (supplied in the PhosLock bottle) inside the filter - don't miss the step of washing the material in the bag before using it as it is really loaded with fine brown dust. A week ago I noticed the hair algae starting to come back which was a sign the PhosLock needed to be replaced. As the filter needed cleaning I cleaned the filter and replaced the PhosLock and I see the algae being eliminated. It hasn't killed any of my fish or shrimp in the tank. I don't consider it "inexpensive" but considering the time I had been spending brushing algae from the planted aquarium plants, scraping glass, etc, all of that has been greatly eliminated or reduced with PhosLock. In my application it was the solution I'd been looking for. I just bought the largest bottle they sell and this review is a result of that purchase. If you have hair algae issues, especially in a planted freshwater aquarium, I'd suggest trying the small container of PhosLock.

PURA Phoslock Excellent

I really like the way this works in my display tank (150 Reef) I use in in a MR1 Reactor and run it constantly. It will not turn to mush and the grain size is large enough that it's not getting out of the Reactor. I do need to rinse it well first and at times the water will turn a little brown but that filters out within an hour. The fact that it will not release phosphate back into the system (as claimed) is important to me and my Phosphate levels are easily controlled with PURA Phoslock.

PhosLock

This is wonderful stuff! It dramatically reduced my phosphates from .5 to .1 within a few hours, and at a much lower price than RowaPhos(my previous favorite). And, I am no longer obsessed by that hair algae!

Algae galor

I had algae growing all over everything, glas, rocks, and even the snails were developing hair algae. I used to use Phosphate beads, but it was a loosing battle. I changed bulbs, salt, and gravel. My wife had enough, and it looked like the end of my hobby. Within two weeks, everything started to clear up, along with agressive water changes. I used this product along with a bag of Chemi-Pure, and like magic my reef aquarium is saved.
