The Hydra 30 is no normal internal filter. Using Hydro-Pure technology that is capable of enhancing the natural filtration processes in aquariums by as much as 50% when compared to conventional systems. With the help of the Cata-Pure Cartridge the traditional nitrogen cycle is sped up as several stages are by passed andunnecessary.

Basically, ammonia in the water (NH3,NH4) – goes straight to Nitrogen ( N2) in one process.  This results in almost instant maturity of tanks, and keeping of Ammonia, Nitrite and Nitrates at very low levels ongoing.

  • Hydra internal power filter.
  • Effectively controls nitrite and nitrate by eliminating ammonia with groundbreaking Hydro-Pure technology.
  • Ultra High Efficiency.
  • Stable Water Quality.
  • Environmentally Friendly.
  • Chemical Free process.
  • Modern filter design to maximize space of filtration.
  • Simple setup and operation
  • Easy to pull apart and cleant.
  • Very quiet motor operation and reliability.

Hydro-Pure Technology

Reduction in the nutrient level in which the biological filtration could not remove. Stable and constant nitrification and denitrification processes.

Anaerobic Chamber

Media (not included) can be added to this chamber for anaerobic processes, where dissolved oxygen is absent or only present in small quantities.

Biological & Mechanical Filtration

A premium filter sponge used to trap suspended debris. High porosity sponge also allows beneficial bacteria to colonise the surface area provided.

The Hydra 30 also acts as a traditional internal filter – trapping dirt and debris in its foam insert. Suitable for aquariums up to 200 Litres.  Unique filter media lasts 12 months.

The Ocean Free filter has only been in a week and we can see a difference in the water already. We had a lot of green weed which has been a nuisance for ages and its getting better. The fish seem happier and more lively too, We are delighted with it. Better than the old one that came with our tank by far. Thank you.

Was advised to buy this for my 60l tank which houses some small tropical fish. Certainly does what it says on the packet however even on the lowest setting, the current is very strong and the filter managed to suck up two tetras within minutes (witnessed!).

I do not recommend for smaller fish or tanks!!!!

Bought a few weeks ago when I set my 50 gallon reef tank up. Gret size and well built. Did a water test about a week after installing and happy to say all readings were zero. Does an amazing job. Crystal clear water as well. 10/10

I bought this product a couple of weeks ago and straight away the water clarity improved within a couple of days. I was a bit skeptical at first about this new technology and after doing a significant amount of research I decided to go for it as there were only a couple of useful reviews available. The design of the filter is great, I'm particularly a fan of the valve on the top that you can attach an air intake to. In the past I've always had to get the filter at the right height on the waters surface to allow aeration. That's no longer a problem thanks to the piping included. The design itself is quite robust so no faults there. There is an anaerobic chamber inside the filter sponge but I haven't used this yet. Obviously the main point is the filter itself and does it work? I've only had 2 filters set up now for a couple of weeks and my ammonia and nitrite levels have remained at 0. The nitrate has remained at 10ppm but after speaking to a member of staff in maidenhead aquatics I was told that the levels would drop to around 0 once a full water change has been done and then it would consistently stay low. I have heard great things about this filter so far, so fingers crossed.

Bought this from the Winnersh Store.
It is extremely well designed and has a lot of good features.
The flow of water out can be increased or decreased according to your need. I have mine pumped up to max with the added aeration tube for bubbles.

It has a large filtration rate and using its hydra technology very quickly cleared up my cloudy water from moving stuff around.

All in all incredible product and it really does reduce ammonia and nitrite readings.
Be aware some test kits mayshow false ammoina or nitrite readings but this is the non toxic forms.
