One of the experts from our technical support staff will be happy to promptly respond. PhosGuard™ needs to be replaced every 4 days as long as there is a phosphate problem because, given an infinite amount of available phosphate, PhosGuard™ absorbs phosphate so quickly that it reaches its full capacity in 4 days. They aren’t directly harmful to your fish but the algae blooms which will occur can deplete oxygen which would then effect your fish. Continuous use of small quantities is better than intermittent use of larger quantities. It does not leach phosphate or silicate back into the water and may be removed, dried, and returned to service until exhausted. PhosGuard™ rapidly removes phosphate and silicate from marine and freshwater aquaria. Seachem PhosGuard – 250ml. Over treating is not recommended. The results of these experiments show that under reef conditions (pH near 8) there is no detectable soluble aluminum released from alumina. If the concentration of the component you are trying to decrease has not dropped to around 0.02 mg/L, then replace the PhosGuard™, otherwise leave in place until levels begin to climb again. A: Although some manufacturer’s claim that their aluminum oxide based phosphate removing products can be regenerated by intense heat, this is, unfortunately, not the case. Started by NCaquatics; Jul 29, 2020; Replies: 1K; Tropical Discussion. Any questions posted over the weekend will be addressed the following Monday. Granular phosphate removers can become compacted, dramatically limiting their capacity to remove phosphate. It has a highly porous quality and spherical shape that allows for maximum water flow and the best results. A healthy planted tank that is getting all the nutrients it needs will (except in the case of gross buildup of nutrients) consume excess nutrients and waste that cause algae, and will tend to prevent major algae blooms without further steps needed by the fishkeeper. There is a misconception that in planted tanks that the uv will take out the ferts you add, but it doesn't. It is not recommended for phosphate buffered freshwater. So, through a series of controlled experiments in both freshwater and saltwater, we intended to address both the question of aluminum solubility and aluminum toxicity. We did find that under conditions of low pH and high dosage levels, alumina releases soluble aluminium; at three times the label dosage rate, we detected 0.2 mg/L aluminium at a pH of 5.3. The evidence to support this claim was largely anecdotal. Aluminum Oxide, Soluble Aluminum, and Coral Toxicity In recent years, there has been speculation that aluminum oxide based phosphate removers like PhosGuard™ release … Seachem PhosGuard – 2L. Continue to test weekly for phosphate until you see it begin to rise again. Ask us a new question. PhosGuard™ is highly porous for high capacity and bead-shaped for optimum water flow.DIRECTIONS: May generate heat on initial contact with water. Distributed in the UK by ALF Limited - Registered in England 2392043, Be the first to review “Seachem Phosguard”. Donate to Mankwe Wildlife Reserve. Over treating is not recommended. Bag Aquarium Fish Tank Filter Media 4.7 out of 5 stars 286. It’s inert and safe to leave in your filter. PhosGuard™ absorbs phosphate, and while fish are more-or-less ambivalent about phosphate levels, plants and corals are not. It is not recommended for phosphate buffered freshwater. Place the product in a high flow rate area and test your phosphate levels, changing as needed. Adding marine water to the dry product may generate sufficient heat to boil the water. No announcement yet. For best results, PhosGuard™ should be rinsed before use and placed so as to maximize the flow of water through it but not so that it tumbles against itself in flow. For best results, PhosGuard™ should be rinsed before use and placed so as to maximize the flow of water through it but not so that it tumbles against itself in flow. They aren’t directly harmful to your fish but the algae blooms which will occur can deplete oxygen which would then effect your fish. That claim is based on a naive interpretation of the information provided by manufacturers of bulk aluminum oxide. Its shape allows for maximum water flow through the media. Office hours: Monday- Friday 9:00 AM - 5:00 PM EST. It may be used in a canister filter, media chamber, box filter, or any high flow area of a trickle filter.
