Product Description

Eheim Substrat Pro is an optimized bio-filter medium which helps to achieve clear, healthy water conditions by providing intensive colonization of the important purification bacteria needed for converting important substances in your aquarium. The 250ml pack of biological filter media consists of pearl-shaped sintered glass. The unique spherical shape of the beads give a high bulk density allowing for full utilization after the first mechanical cleaning process is completed (e.g. EHEIM MECH or MECHpro).

Eheim Substrat Pro works by reducing peak nitrate loads with ease and in turn, increasing maintenance intervals - thus reducing the time needing to be spent on keeping the water conditions clean manually. 

Suitable for freshwater and marine aquariums, Eheim Substrat Pro can be washed and re-used.

  • Vibrant plants

    First purchase this week and I was so pleased. The plants were so healthy and vibrant. It's got me thinking about replanting my other tank with more plants! Will definately be buying from them again

  • Amazing place!

    Wow! Was recommended to visit and have to say that anyone looking for plants and equipment this is definitely the place to go.
    Amazing range. Not the normal few plants chucked into a tank. Absolutely incredible. Very friendly and knowledgeable staff.

  • Quick service, fantastic plants

    I have ordered from Aquarium Gardens for the first time after seeing them on social media. Well what can I say except WOW, the plants were a really good price, they arrived on time actually quicker than I expected! They arrived in absolutely fantastic condition as if I had picked them out myself, well packaged. The plants themselves were bigger than what I expected to get so definitely value for money and the root systems were well established, can't wait to see them get bigger in my aquariums. Will definitely buy from this company again.
