A: We do not recommend it, as the tumbling action of a media reactor can cause this media to produce dust. Even at three times the dose of PhosGuard, soft-bodied corals such as Sarcophyton remain unaffected. If the flow is too high then it can cause the GFO to break up and cloud your tank; adversely, if there is not enough flow, it can clog and be difficult to clean the reactor. Seachem does not recommend using PhosGuard in a media reactor because the swirl of the granules in the media reactor can produce dust. However, heat cannot result in phosphate release from aluminum oxide due to a difference in the nature by which phosphates are bound to aluminum oxide versus adsorbed gases. in it. My betta tank after s few scrubbings and wc is almost clear. JavaScript is disabled. When placed in a fluidised reactor or canister filter it is possible to measure zero phosphate leaving the canister, the flow should be turned down until that is achieved.

Does it prevent any new diatoms from forming or does it eliminate any diatoms that's already there or both? Its only a little reactor, but then its … 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. Only 6 left in stock (more on the way). yep this is the planted tank. There are obviously there if you have diatoms. Phosguard absorbs phosphates, and biopellets are essentially porous media to grow bacteria, just as your liverock and existing filter does, to reduce nitrates.

The trusty go-to granular ferric oxide (GFO) gets a boost in both of these products with PhosBond combining GFO with aluminum oxide and PhosNet taking regular GFO up a notch with high porosity, high surface area and high binding capacity. I always kept them off the glass but they made my plants look dingy, dirty and unhealthy instead of bright green. The directions said I L to 300 gal. 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.
