A unique fluidising plate designed to help keep the Media in suspension and evenly disperse the water upwards for greater removal of bacteria.

Every 100g of Bio-Phos is capable of removing up to 4ppm of PO4 from 1000 litres of salt water or 4ppm PO4 from 2000 litres of fresh water.


A specially formulated bio-active media designed to promote the growth of Nitrate and Phosphate reducing bacteria and associated Enzymes. Easier to use, lower maintenance and more economical than Carbon or Phosphate removal media. Suitable for all types of Marine and Freshwater Aquaria.


Bio Pearls are designed to reduce Nitrates and Phosphates. Here at Bio Aquatek Ltd we have designed a formula tailored, specifically to the needs of hobbyists and commercial operations alike. Marine Bio Pearls/Pellets contain no unwanted ingredients and are none polluting.For all marine enviorment.

Marine Bio Pearls / Pellets work by encouraging the growth of bacteria and enzymes on their surface, by providing essential nutrients required for growth. By multiplying, the bacteria and enzymes break down the Marine Bio Pearls/Pellets whilst consuming both Nitrates and Phosphates from the water column.
Once these unwanted nutrients have been reduced to trace levels, the bacteria can no longer feed on the Marine Bio Pearls/Pellets, and a stable state is reached. If the levels of feeding or waste production increase in the tank, the Marine Bio Pearls/Pellets will start to consume them again.

Whilst skimming remains an effective solution in marine aquaria, it has its weaknesses. Only approximately 30% of the unwanted nutrients in the water can be captured by a skimmer. The rest are not capable of sticking to the surface of the skimmer bubbles. Marine Bio Pearls / Pellets help in two ways.
Firstly, they consume these nutrients and convert them into slime coated bacteria, which can be skimmed, and secondly, the sticky surface of the bacteria capture minute particles of waste from the water column as they pass through the skimmer, thus removing them before they break down.

You will see a marked improvement in water clarity and colour, as a result!

Use 100 – 150ml of Marine Bio Pearls / Pellets per 100 litres of tank volume (You may not need them all at once)

Marine Bio Pearls/Pellets should be placed in a fluidising reactor, with sufficient flow to keep them moving strongly. If they start to clump or slime up, they will be less effective and may turn anaerobic, producing hydrogen sulphide.

In cases where you have high nutrient levels to start with, the powerful action of the Marine Bio Pearls may overrun your skimmer and possibly bring down levels in the tank too quickly. In such cases, it is better to start with half or less of the Marine Bio Pearls/Pellets until your nutrient levels reduce. At that point, the rest can be added. Please note that your skimmer may stop working for between 2 and 7 days (depending on the skimmer) while the Marine Bio Pearls/Pellets “run in”. This is similar to the running in period you experience with a new skimmer and is nothing to be concerned about. The skimmer will quickly catch up again once the Marine Bio Pearls start to do their work. It may take between 2 and 6 weeks for the Marine Bio Pearls/Pellets to become fully functional and is partly dependent upon the level of nutrients in the system, the more nutrients, the faster the Marine Bio Pearls/Pellets will start to work.

In order for the process to be effective, it is necessary to operate an efficient skimmer, capable of capturing the bacterial waste produced by the Marine Bio Pearls. It is essential that the Marine Bio Pearls / Pellets reactor waste is positioned close to the skimmer inlet in order to capture the maximum amount of waste produced. Any small amounts of bypass will get consumed by a wide range of corals.

Your Marine Bio Pearls / Pellets will be effective until they completely disappear, which will normally take in excess of 12 months. However they should be lightly topped up every 3 months, back to their original quantity, to maintain maximum effectiveness.
