Dennerle Plants UK: aquatic plants and aquascaping supplies by mail order

Dennerle Plants UK is an online store specialising in live aquarium plants and the equipment needed to grow them. The catalogue is organised around more than 70 species and is aimed both at people setting up a first planted aquarium and at aquascapers looking for specific varieties. Orders are shipped only within the United Kingdom.

The range is grouped by difficulty (easy, medium and advanced), by placement in the tank (foreground, midground, background, carpeting and floating plants) and by format, distinguishing tissue culture plants from potted plants, epiphytes and mosses.

Plant formats and collections

Two presentation formats are highlighted. Tissue culture plants are grown in a laboratory under sterile conditions and, according to the company, are completely free from pests, snails and algae. Potted plants are described as strong specimens ready to be placed directly in the aquarium.

Beyond the general catalogue, the store lists several curated selections:

• Special Edition Plants, produced in limited quantities and presented as rare or carefully selected varieties with distinctive shapes, colours and textures.
• A dedicated Anubias collection, including variants such as Anubias barteri 'Nana', 'Nana Bonsai', 'Petite', 'Pangolino', 'Kleinblättrig', 'White' and Anubias heterophylla.
• Categories for rare plants, colourful plants and special offers.

Individual listings in the scanned material include Bucephalandra pygmaea 'Bukit Kelam', Bacopa caroliniana, Hygrophila pinnatifida, Hygrophila odora, Littorella uniflora and Bolbitis heudelotii.

Substrates, CO2 and fertilisers

Alongside plants, the shop sells its own Dennerle Plants line of care products and the Yokuchi collection. The substrate range separates Soil from Substrate. Soil is described as a nutrient-rich active substrate that lowers carbonate hardness and stabilises pH, ready to use straight from the bag without a gravel layer. Substrate is presented as a long-term nutrient base layer that releases nutrients when needed and absorbs them when in excess, always used under a top layer of gravel or soil.

For CO2, the store offers a Starter Kit based on yeast fermentation, described as a simple and inexpensive solution for small aquariums, together with refills and a diffuser. Fertilisation includes Liquid and Liquid Plus, containing iron, potassium and trace elements and intended primarily for tanks with few plants or a high fish population, as well as Power Caps capsules placed in the substrate with nitrate, phosphate, potassium, iron and trace elements.

Other product lines in the catalogue are water treatment, terrarium items, Twinstar aquarium lights and aquarium sterilisers.

Guidance for planted aquariums

The site devotes a learning section to algae, covering prevention, common types and what algae are, and to practical topics such as plant melt, plants for beginners, water conditioner, Shõka bacteria and carbon nutrition. A step-by-step introduction addresses light, substrate, plants, water, nutrients and CO2. The company also publishes a blog with tips and guides for planted tanks.

Ordering and customer service

Shipping is limited to UK customers. The FAQ states that orders generally take between 5 and 7 business days to arrive. Tissue culture cups are said to last 2 to 3 weeks on average under optimal conditions, depending on plant type and growth rate, and should be kept away from direct sunlight and about 30 cm from artificial light sources. Handling instructions advise keeping the lid closed until use, then washing off the gel or liquid medium with lukewarm water without applying too much force.

Customer support is available Monday to Friday from 8am to 3pm, with an average answer time of 24 hours. The site also mentions a newsletter sign-up offering a 10% discount and a wholesale section.
