We all like to keep beautiful, healthy tanks. But whether you have a tropical, freshwater or marine tank, problems are bound to arise from time to time as seemingly small factors can affect the delicate balances in your tank.

We also offer our own treatments and additives including Swell Aquarium Rapid Nitrite Remover, Swell Aquarium Water Clarifier, Swell Aquarium Blackwater Extract, Swell Aquarium Phosphate Remover, Swell Aquarium Nitrate Remover, Swell Aquarium Nitrite Remover, Swell Aquarium Ammonia Remover and Swell Aquarium Stress Reducer.

What are treatments and additives?

Treatments and additives are chemical or biological mixtures that you add to your aquarium water to fix a problem, such as an increase in pH or the presence of a disease in your water. Most treatments and additives only need to be used once but some may need several doses to take effect.

Why should I buy treatments and additives?

Just like medication for a human, treatments and additives are generally used to counteract something - often after using an aquarium test kit. However, like keeping some basic medication in your home, it can be a good idea to stock up on some of the most common treatments, so you can act immediately if you notice a change in your tank or water chemistry.

What are the main types of treatments and additives?

In our treatments and additives range, you’ll find a wide variety of treatment types including; Aiptasia & pest control, ammonia removers, aquarium algae treatments, aquarium dechlorinators, aquarium filter starters, aquarium fish disease treatments, buffers, cloudy water treatments, coral dips, freshwater aquarium additives, marine aquarium additives and phosphate & nitrate removal. Each treatment or additive is sorted by what it does so their purpose is generally self-evident but you can find more information on the category pages for each type of treatment or additive.

What should I look for?

When buying treatments and additives, the key is in the ratios. Check to see that the treatment or additive you’re buying will have enough in it to treat your whole tank as many times as is required. If you have a particularly large tank you may find that you need to invest in multiples of the same product to ensure you have enough to hand.
