It continues to do this until the head pressure can no longer force water through the small holes and it overflows.The ClariSea works in exactly the same way except that instead of overflowing and having to change or clean the bag, it automatically rolls on to expose a fresh piece of material. The fresh fleece will allow larger particles to pass through and the dirtier material will stop smaller particles.\u003cbr\u003e\u003cbr\u003e\u003cdiv\u003eFlow Rate vs Filter Life\u003cbr\u003e\u003cbr\u003eThe higher the flow rate through the fleece, the less time the roll will last. Imagine it as a large group of people trying to leave a building through one door. The slower and more organised they try to leave, the easier it is for individuals to bunch together and to fill into small gaps in the crowd, like water and small particles finding their way through small holes in the fleece.Compare this with people trying to leave quickly in a panic, and chaos is created, so that people back up around the door, like the water level backing up and triggering the float to move on the roll in the ClariSea without it becoming fully saturated with dirt.\u003cbr\u003e\u003cbr\u003eFactors affecting the life of the fleece are:\u003cbr\u003e\u003cbr\u003e1 - Water flow (volume)\u003cbr\u003e2 - Filter installation height above the water.\u003cbr\u003e3 - Dirty tank. With most aquariums you will find that they act as large settlement chambers and that particles of food, detritus and dead bacteria settle within the sand or substrate. The clarisea will remove this detritus from the water before it gets a chance to settle but will also remove sediments from the substrate as it is stirred up by fish or manually. The rolls in the early days may last for a shorter length of time and should be seen to last longer and longer as the tank is cleaned.\u003cbr\u003e4 - Greedy fishTanks with high stocking loads of hungry fish will dirty the roll faster but keep your aquarium sparklingly clean whilst removing uneaten food before it breaks down\u003cbr\u003e.5 - Excessive Carbon DosingCarbon dosing works by growing bacteria in the water column that are then exported out of the system by skimming or filtration. Excessive carbon dosing can result in bacterial blooms which are seen as a slight cloudiness of the water. The ClariSea fleece is fine enough to remove these bacteria from the water but when in high volumes will blind the fleece and reduce it's life. If you notice this then we suggest slowly reducing the amount of carbon source added. Equally the installation of the ClariSea after a Nitrate Filter will also reduce the life and give a pale coloured roll from the white bacteria.\u003c\/div\u003e","brand":"D-D","offers":[{"title":"Default Title","offer_id":40199654146183,"sku":"34056","price":53.8,"currency_code":"GBP","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0563\/6387\/6487\/products\/clarisea-xl-fleece-for-sk5000-3-pack-440652.jpg?v=1731256087"},{"product_id":"sicce-shark-pro-venturi-set","title":"Sicce Shark PRO Venturi Set","description":"\u003cp\u003eSicce Shark PRO Venturi Set\u003c\/p\u003e","brand":"Sicce","offers":[{"title":"Default Title","offer_id":40199654342791,"sku":"481226","price":5.64,"currency_code":"GBP","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0563\/6387\/6487\/products\/sicce-shark-pro-venturi-set-688821.jpg?v=1731257376"},{"product_id":"autoaqua-smart-ato-nano","title":"Autoaqua Smart ATO Nano","description":"Smart hang on automatic top up unit designed for small or nano aquariums with a dual safety sensor and diaphragm pump that can draw water from a reservoir next to a sump or from below in the aquarium cabinet.\u003cbr\u003e\u003cspan\u003e\u003cbr\u003eA strong diaphragm pump and a dual optical sensor are combined in one compact hang on unit so there is no pump to fit in the reservoir, keeping everything neat and tidy.\u003cbr\u003e\u003c\/span\u003e\u003cbr\u003e\u003cdiv\u003eFeatures\u003cbr\u003e\u003cbr\u003e\n\u003c\/div\u003e\u003cspan\u003e• Dual sensor with safety backup\u003cbr\u003e• Built in status indicator lights\u003cbr\u003e• Smart time out emergency function\u003cbr\u003e• Compact hang on design\u003cbr\u003e• Easy to install, plug and play\u003cbr\u003e• Includes intake prefilter\u003cbr\u003e• Built in pump for less cables\u003cbr\u003e• Check valve to prevent siphoning\u003cbr\u003e• Diaphram pump\u003cbr\u003e• Magnetic Mount for sensor\u003cbr\u003e\u003cbr\u003e\u003c\/span\u003eCompact Design\u003cbr\u003e\u003cspan\u003eIntegrated with one dual smart sensor and one diaphragm pump the Smart Nano ATO is extremely easy to install on your aquarium — hang it on the side of the tank or outside edge of the sump, connect tubing, and plug in the power.\u003cbr\u003e\u003c\/span\u003e\u003cbr\u003eEasy to Assemble\u003cbr\u003e\u003cspan\u003eThe toolless design allows you to assemble and disassemble the Smart Nano ATO fully for maintanence in a minute, no screws or awkward fixings\u003cbr\u003e\u003c\/span\u003e\u003cbr\u003eSimple Installation\u003cbr\u003e\u003cspan\u003eThe ‘Hang-On Back’ design simply slips over to top edge of the aquarium or sump and clamps into place using an adjustable holder suitable for 3-10mm thick glass.

nitrite), you should purchase the BIO Plate. \u003cspan\u003eOne important criteria in marine systems is gas exchange.  Xport is the best bacterial media in the world, but it is not good at gas exchange.  Bio balls are the best for gas exchange, so any system will work better with a small stack of bio balls placed in the main flow (in air).\u003c\/span\u003e","brand":"Brightwell Aquatics","offers":[{"title":"Default Title","offer_id":40199656636551,"sku":"32736","price":86.49,"currency_code":"GBP","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0563\/6387\/6487\/products\/brightwell-xport-no3-removal-plate-588566.jpg?v=1731256004"},{"product_id":"brightwell-xport-bio-brick","title":"Brightwell Xport Bio Brick","description":"Ultra-porous ceramic Brick shaped Biological Media with Superior Performance Characteristics\u003cbr\u003e\u003ch3\u003eOverview\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003eDesigned to be used in marine and hard freshwater aquariums with a pH of 7.5 or over\u003c\/li\u003e\n\u003cli\u003eHighest porosity and largest useable surface area, per unit weight or volume, of all filtration media available anywhere\u003c\/li\u003e\n\u003cli\u003eProvides huge amounts of aerobic and anaerobic surface area for efficient bacterial colonization.\u003c\/li\u003e\n\u003cli\u003eLaboratory Tested: Provides over 71,000 square feet (6,596 square meters) of surface area per liter of medium.
