No more Fluidize Media Reactors or deep Sand Beds Filters required which saves space, time and Money
100% natural, biological Nitrate removal
No effect on pH or alkalinity
MASSIVELY Reduces Water Changes
Nitra-Guard BIO-Cubes Titanium is the world’s first and only carbohydrate based nitrate remover that is able to remove nitrates in systems with no phosphate present.
Standard carbohydrate based nitrate removers must have some phosphates in order to work. Once the PO4 levels have dropped to 0ppm, the carbon based media stops working. This has been a problem for aquarists who wish to run PO4 removal media and lower nitrates at the same time.
BIO-Cubes Titanium are made from 100% biologically degradable polymers that effectively remove both nitrates from both marine and freshwater systems. BIO-Cubes Titanium have a very high surface area and contains 400% more carbohydrates than any other brand, making it not only the best product of it’s kind in the world.
BIO-Cubes Titanium are very versatile and can be used in filter bags, fluidized reactors and denitrators. BIO-Cubes Titanium require no maintenance and require no feeding dosages making it the easiest and most convenient nitrate removing product on the market. Nitra-Guard BIO-Cubes Titanium comes with a free filter bag with every jar.
500 ml treats up to 174 gallons depending on Nitrate Levels.
Directions for Use:
Bio-Cubes Titanium will not cause cloudiness from bacteria blooms. With correct installation, bacteria colonies will become prolific enough to start lowering nitrate levels within 7-14 days. Free filter Bag is included for ease of installation.
The amount required will depend on stocking densities and amount of Nitrate in the aquarium.
500 ml treats up to 174 gallons depending on Nitrate Levels.
Below 15ppm NO3: 0.75ml p/L water
15ppm – 30ppm NO3: 1.5ml p/L water
30ppm – 60ppm NO3: 2.5ml p/L water
Above 60ppm NO3: 3.4ml p/L water
ORCA LABS Nitra-Guard Bio-Cubes Titanium for Nitrate Control
The Titanium version of Nitra-Guard is built to keep working even when your tank’s nutrient balance is skewed, making it a steadier long-term nitrate solution for demanding systems. Like the Original, it hosts denitrifying bacteria that consume nitrate across freshwater, brackish and marine setups, so you can place it in flow and largely leave it to do its job. For Singapore reefers and busy community-tank owners, that means fewer water changes spent chasing stubborn nitrate.
As with any biological media, results build gradually as the colony matures, so test regularly rather than expecting an instant reading change. We still pair it with good husbandry, since no media offsets serious overstocking or overfeeding. Keep adequate flow over the cubes; in our warm 27-29C tanks, active bacteria need both contact with the water and a steady, low-oxygen pocket deep in the media to reduce nitrate effectively.
Browse the full filter media range, and pair this with our nitrate explainer and best biological media guide to plan your filtration.
