Seachem Clarity

Earn up to 26 FBPoints.
  • Reef and plant safe
  • Water clarifier for marine and freshwater
  • Clears all types of clouding


Clarity™ is the ultimate clarifier for both fresh and saltwater. It employs an advanced polymeric flocculating agent that is both reef and plant safe. Clarity™ is the only clarifier on the market that does it all! Clarity™ will clear all types of clouding. Many companies manufacture multiple products to clear up each type of cloudiness and each different environment (e.g. freshwater, marine, reef, etc.). Some companies have developed products that will clear most types of cloudiness, but their application requires two separate bottles of product. Clarity contains compounds that will clear all types of cloudiness in all environments. Clarity contains both precipitating and flocculating agents in the same bottle, enabling all types of cloudiness to be removed in one dose. Upon adding Clarity™ to the water, you will see a cloudy haze begin to form. This is normal and means that Clarity™ is beginning to work. The water is filled with tiny pieces of floating matter that were not visible to the naked eye. Clarity™ makes those pieces of matter begin to clump together. As they clump together they form larger pieces of matter that are now visible, hence the cloudiness. Once this matter has clumped together, it is a simple matter of mechanical filtration to remove the residue. Matter that was once too small to get caught in filter media is now in large enough clumps. In order for Clarity™ to work effectively, you should have a filter with mechanical filtration (e.g., filter floss) connected to your aquarium.


Use 1 capful (5 mL) for every 80 L (20 US gallons). In some situations the cloudiness may increase after adding Clarity™, however this is normal and is a sign that Clarity™ is actively working. Rapid clarification will follow (1–2 hours). In the case of chemical or particulate clouding clean filter floss or cartridge after tank clears.

NT LABS Aquarium Algae Gone

Earn 12 FBPoints.
100ml When to use? Green water/algae caused by over feeding and fish waste is unsightly in an aquarium, and can be dangerous as it may alter the pH and oxygen levels. Algae Gone is a single-dose, plant-friendly treatment that will clarify the green or cloudy water in your aquarium. It works by clumping the minute particles together enabling your filter to strain them out. Algae Gone will also help to lower algae- causing phosphate, thereby promoting a healthier aquatic environment. Use when the water has become green or cloudy. How to use?
  • Calculate the volume of your aquarium in litres (Length x Width x Depth (in cm)/1,000). Alternatively, use our Dosage Calculator to help you.
  • Shake the bottle thoroughly before use.
  • Mix required dose of treatment with 1 litre of aquarium water.
  • Add slowly to aquarium.
Warning: Keep your aquarium away from direct sunlight and test your water for algae-fertilising nitrate using NT Labs Test Kits. “Comprehensive and easy to use, I often like to have a couple of bottles of Anti-Internal Bacteria treatment or Disease Solve to hand. Nice to know that I’m not the only one who rates these products!” Nathan Hill, the Associate Editor of Practical Fishkeeping Magazine FAQs: Q: How does Algae Gone kill algae? A: Technically, Algae Gone is not an algaecide so it won't kill algae immediately like a weed killer would on your unwanted garden plants. Instead, Algae Gone causes the particles of the single-celled algae, which cause green water, to clump together, allowing you to manually remove them from the water column or the filter. As a secondary effect, Algae Gone will remove phosphate from the water which the algae would previously feed off, starving the algae with repeated use. Q: How long will Algae Gone take to clear my aquarium? A: This is impossible to say. It will depend on how severe the problem is, the type of algae, why the problem has arisen in the first place and the house-keeping factors of your aquarium. Regular use of the product will result in less algal growth due to the removal of phosphate, whilst manually removing the algae will reduce the amount of algae which would otherwise continue to grow simultaneously. For instant results, manual removal of any visible algae is probably your best option. Q: How often can I use Algae Gone? A: You can use the product weekly as part of your general aquarium maintenance regime. Ensure you do a water change before dosing the aquarium according to the instructions. Q: Can I use Algae Gone at the same time as Phosphate Remover? A: Yes, you can. Q: After adding Algae Gone, my water has gone cloudy. Is this normal? A: Yes, this is a precipitate which forms as the product binds to phosphate molecules in the water. It won't harm your fish, plants or filter bacteria. Q: Do I need to remove Activated Carbon or other carbon-based filter media whilst using Algae Gone? A: Yes, remove any carbon-based media from your filter when you add the dose of Algae Gone. This product is quite fast acting so the media can be returned to the filter after 36 hours.

Interpet Green Away

Earn 10 FBPoints.
Size: 125ml Clear away ugly green water with this specialist treatment. Plant and fish friendly.

Key features

• Fast acting for speedy aquarium maintenance • Enhances mechanical filtration with its clever clumping mechanism

Product overview

Green water isn't a good look for aquariums. It doesn't only look horrible, it's really bad for your fish too. Excessive light or nutrients can trigger this ugly and potentially dangerous algal bloom in your aquarium which can affect oxygen and pH levels. This makes the water highly alkaline and potentially dangerous for your fish. But help is at hand. Green Away neatly clumps the suspended algal particles so they can be trapped by your filter or sink to the bottom and be syphoned off when you do your next water change. Use for treating Green Water or "Pea Soup", and remove unsightly brown or green algae suspended in your aquarium.

EIHO Chito Clear

Earn up to 20 FBPoints.
EIHO Chitoclear Clarifies cloudy water using natural polymer Aids in binding organic waste Does not affect pH CHITO CLEAR is a specially formulated clarifying solution containing natural polymer (chitosan). This natural polymer binds dirt, micro-particles and oil in the water, which will be then trapped in the filter media so water is restored to clear and pristine conditions. Results can be seen after the first usage. Constant addition will also aid in the removal of organic waste and reduce ammonia, phosphate build up. CHITO CLEAR is safe to be use with fishes, invertebrates and plants. WHY CHITO CLEAR? The active polymer, chitosan is safe and natural. There will not be long term accumulation in the aquarium. This is unlike most common water clearing agent which contains heavy metals such as aluminum or iron. The accumulation of heavy metals will affect the health of fishes. Furthermore, CHITO CLEAR is a clarifying solution that will not create pH swing, so it can also be used in aquariums with low carbonate hardness. DIRECTIONS Use (1cap) 5ml for every 50L. For best result, please use with filter wool, filter sock or sand filter. Water clarity will improve after first usage. In some cases, water may increase in cloudiness after usage, this shows CHITO CLEAR is actively binding and will clear up after 24 hours. To further improve clarity and aid in removal of organic waste, please add once a week. Active ingredients: Chitosan
