How does Seachem Matrix compare with Seachem Denitrate?
1163857
matrix has the most surface area for BB to grow ... denitrate is like a cross between purigen and matrix an organic absorbent porous for BB to grow material but not as good for BB as matrix still a nice twist

According to the seachem page for denitrate, it should only be used in lower flow applications where flow is less than 50 gph (200 lph). If higher flow rates are present it will not work to denitrify the water and matrix should be used.

you have three different bens, bottom ben has two slots - this should have the bio-foam, the next ben up or the center ben should have two slots of bio-max - the top ben should have a polishing pad in the bottom of each slot and a bag of seachem on top of pad in each slot. This combination should remove all particles and am not sure if it will remove your nutrients

Yes, Marineland's carbon is cleaner than most, requiring less rinsing to get rid of the carbon dust before you put it in the filter. I strongly recommend using a filter bag to contain the carbon before putting it in a filter.

i read that seachem purigen can also be ruined if you use dechlorinators that have slime coat agents in them, like aloe and other slimy stuff. like API Stress coat - you cant put that in your tank if you are using purigen or other polymer resin type stuff and it also ruins certain other medias like DeNitrate by coating or clogging it up.

well you have trays inside that hold the fluval g-nodes. and what comes with the unit doesnt fill all 3 baskets full so if you fill 2 of the 3 baskets full then you could put your seachem purigen in a mesh bag in the 3rd tray with gnodes around it.

I have checked MARINELAND website, but they don't have listed MSDS (Material Safety Data Sheet) to the product. However, it seems to me the whitish color indicates baked activated clay. The activated clay is very typical anmonia absorption material. I have changed the White Diamond once or twice in a month to 50-gallon tank. Actually, I have not seen any high NH3+ in the tank water.

Thank you for contacting AquaRain Support. Water conditions can be of great concern, especially when traveling to developing countries and the AquaRain has been designed specifically for this reason. Since bacteria vary greatly in size, porosity alone will not define the efficacy of a filters performance. The internal pore structure has a great deal of influence on ceramic filter performance. Testing with live organisms is the best determinate of performance. Our filters have been tested using the EPA protocols in a unique way. Our ceramic test articles were abraded down to 10% below their measured end-of-life and exposed to contaminated water before being sent in to the laboratory for testing. This was done to confirm that our ceramic filters were fully effective and safe to use until they reach their measurable end-of-life. Normal testing protocols only use brand-new, hand selected articles for testing and are therefore unreliable where the water quality is of concern. We went further and tested our filters with Brevundimonas diminuta, a very small bacteria used for testing in the health industry. We met EPA purifier standards even when using this much smaller test organism. Because of our real world testing results with this live organism, we realistically rate our ceramic pore size at .2 micron absolute. We have a great deal of information on our website especially, under the "testing" tab. There you will find a downloadable PDF Testing Summary Sheet for our ceramics. I hope this has answered your questions, please write again or contact us directly should you have any further questions. Kind Regards, AquaRain, Inc.

Like a few other responses I've never used RowaPhos but I can tell you this bag has the finest mesh of any bag I've ever used. Are you familiar with Seachems purigen? if so, you know how tiny the purigen media is. if not their extremely small and this mesh bag holds them fine....

I have used Seachem -Excel for the last 8 months and did not find any problems with guppies.

Not sure exactly what you mean, but it has ammonia, nitrite, nitrate, low range pH, and high range pH. Each test will do, i dunno, 100? 200? tests?I'm sure API customer service could give you a more precise answer, but I've never run out of any bottle before the expiration date in 20+ years of using them.

No. The filter has 4 trays. Each tray holds one liter. (My original answer of 2 liters was wrong) Also you usually want to fill the bottom (first) tray with a mechanical filtering medium like Eheim Mech. It can be pretty expensive to fill up the filter but the medium will last a long time. I use a tray or two of Seachem Matrix in addition to Substrat Pro. It is less expensive and works well for me. I'm not sure which is better, but by using both I save money and have another kind of medium in the filter. Hope this helps.

Nope they are not the same. This leaf zone prevents your the leaves of your plants from getting transparent due to lack of potassium. I would get this leaf zone and flourish excel. And skip seachem flourish. Flourish and flourish excel is not the same. I know kinda confusing at first.

Matrix is just really porous rock. Like volcanic rock. If you're asking with intention to use it to leech copper out of a system, no it won't do that. It may have some copper absorb on it. I know I sure wouldn't reuse any of it that has been exposed to copper in a system with any life that could be harmed by it. One shrimp = 2 of these matrix containers. Not worth the risk.

Nitrite is the bi product of ammonia breakdown. You can't just add stress zyme to get rid of nitrite. Best way to avoid ammonia and nitrite problems is to properly cycle your tank if you don't want to hurt your tank such as popping a frozen shrimp the shrimp will decompose and create ammonia waste because of the inherent proteins inside. There is naturally occurring bacteria everywhere that will consume ammonia and will quickly multiply in the aquaria especially if you use a Heater and have your water temperature in the high 70s. Soon your "biological filter" will build up that can handle the waste of ammonia and nitrite. The thing about stress zyme that doesn't work is that you can't rush the cycle no matter how much of this stuff you use. Also you need lots of gravel and decorations and filter media to provide surface area for potential growing spots for bacteria. In short if you are having nitrite problems you might want to do daily water changes to your tank until your biological filter matures and your tank is properly cycled and make sure you add fish slow so the biological filter can grow with the increasing demands of fast increases in ammonia and nitrite that would not be handled by the current number your bacteria in your tank. Remember bacteria growth is pretty fast so save your money and just do some extra water changes. Nothing you will add except for dilution of the problem will fix it. Keep checking your levels until you no longer test ammonia or nitrite levels past zero and you will know your tank is properly cycled. Remember nothing good happens overnight in this hobby, be patient and you won't lose any fish.

They are virtually the same, they each use a copper node of some type that helps kills stuff in the water. Sorry this is the off the cuff explanation. The saltwater system works in that it uses the salt to generate chlorine through titanium plates. The add the oxygenation to the water to help in cleaning. That's only what I have read. I highly recommend the newer version of the system that is pictured here. Much better than chlorine based systems.

Seachem Excel Flourish provides a source of carbon that is used in photosynthesis, so it depends on where the "bottleneck" is in your aquarium. If you have enough lighting that the plants are using the dissolved CO2 before it is replenished, then Excel will speed the plants' growth. There are ways of estimating the CO2 levels in your tank using pH and KH (hardness/alkalinity). I would suggest trying that to see whether the excel would help or not.Helpful link:http://fishfriend.com/aquarium_co2_calculator.html
