Description
SPECIFICATION
Plant growing systems for use in aquaria
This invention relates to plant growing systems for use in aquaria.
There are several problems associated with growing aquatic plants in aquaria. Under-gravel filtration systems present in many aquaria cause considerable water movement through plant growing media at the bottom of the aquaria. This water movement has a deleterious effect on the root and general growth of most aquatic plants. Furthermore the pH conditions present in the aquarium may not suit the aquatic plants growing therein.
According to one aspect of the present invention, there is provided a container to be located in an aquarium and containing a growing medium for aquatic plants, said container enclosing the medium on all sides.
According to another aspect of the present invention, there is provided a plant growing system for use in aquaria, the plant growing system comprising a container containing a growing medium for aquatic plants, said medium having a selected pH.
According to another aspect of the invention, there is provided a plant growing system for use in aquaria, the plant growing system comprising a flexible permeable container containing a plant growing medium composed of a mixture comprising peat, minerals and nutrients in proportions which give the medium an acid or a neutral or an alkaline pH suitable for growth of aquatic plants which grow in acid, substantially neutral or alkaline water, respectively.
According to yet another aspect of the present invention there is provided a container located in an aquarium, the container containing a plant growing medium and aquatic plants growing in said medium, the pH of the medium being selected in accordance with the pH of the aquarium water.
According to another aspect of the present invention, there is provided a group consisting of a plurality of plastics bags at least one bag containing a plant growing medium having an acid pH which is suitable for growing aquatic plants in water having an acid pH, at least one other bag containing a plant growing medium having a neutral pH which is suitable for growing aquatic plants in water having substantially neutral pH and at least one bag containing a plant growing medium having an alkaline pH suitable for growing aquatic plants in water having an alkaline pH.
In general plants prefer to grow in specific pH conditions (i.e. in an acid, neutral or alkaline environment) so that the pH or hardness of the aquarium water will effect the type of aquatic plants which will grow successfully. It has been found to be advantageous for plant growth if the pH of the growing medium is complementary to that of the water so the pH of the plants whole environment is determined. Thus for optimum plant growth in a soft or acid water aquarium, aquatic plants which thrive on acid conditions should be grown in an acid growing medium. Similarly, in a hard or alkaline water aquarium, aquatic plants which prefer alkaline conditions should be grown in an alkaline growing medium. In neutral or substantially neutral aquarium water (for example having a pH of from 6.8 to 7.2), aquatic plants which prefer neutral conditions should be grown in a neutral growing medium.
Containers embodying the invention will now be particularly described by way of example only, with reference to the accompanying drawings, in which:
Figure 1 is a plan view of a container containing plant growing medium;
Figure 2 is a cross-section through the container of Fig. 1; and
Figure 3 is a side view of the container of Fig. 1 and Fig. 2 in use.
The illustrated container comprises a bag 1 of plastics material sealed at both ends. The plastics material can be thermoplastics, for example 400 gauge polythene and the bag 1 sealed by heat sealing to form external seams. The bag 1 is perforated with holes of a size which make it permeable to water but are sufficiently small to prevent growing medium escaping from the bag 1. For example the holes can be pin size or approximately 0.5 mm in diameter, spaced at approximately 0.5 inch intervals throughout the bag. Inside the bag 1 is a plant growing medium 2 which is suitable for growing aquatic plants and has a selected pH (i.e. acid, neutral or alkaline).
The plant growing medium is preferably composed of a mixture comprising peat, minerals and nutrients, although other suitable mixtures can be employed.
The level of nutrients in the mixture is sufficient to allow for a speedy onset of growth in a newly set-up tank and at the same time low enough to encourage good root growth into the growing medium. The nutrients can be mixed with the peat and minerals prior to packaging or they can be injected into the bag during the packaging stage in the form of an aqueous solution.
An example of a suitable nutrient composition is as follows:
NUTRIENT FORMULAE AMOUNT
Calcium Nitrate Ca(NO3)2.4H2O 0.0612 grams
Magnesium Sulphate MgSO4.7H2O 0.0493 grams
Potassium Nitrate KNO3 0.0202 grams
Potassium Dihydrogen
Phosphate KH2PO4 0.0272 grams
Ferric Chloride Fe3CI 0.0005 grams
Micronutrient solution (as below) 0.1 c.c.
MICRONUTRIENT
SOLUTION FORMULAE AMOUNT
Distilled water H2O 1 Litre
Boric Acid H3BO3 2.5 grams
Manganese Chloride MnCI2.4H2O 1.5 grams
Zinc Chloride ZnCI2 0.10 grams
Copper Chloride CuC12.2H20 0.05 grams
Molybdenum Oxide MoO3 0.05 grams
The remaining components of the mixture are selected according to the pH or hardness of the water in the aquarium. Examples of a mixture suitable for use in acidic, neutral and alkaline environments are as follows:
ACIDIC ENVIRONMENT a. Peat
(Finnish peat with dust removed) . . .10 units by weight b. Breedon Rock " II chips (Magnesium Limestone).. ...13.5 units by weight c. Neutral Balast
(Ordinary coarse sand) . ...31.5 units by weight
NEUTRAL ENVIRONMENT a. Peat .. 10 units b. Breedon Rock ...48.5 units
ALKALINE ENVIRONMENT a. Peat . ...10 units b. Breedon Rock ... 45 units c. Powdered Calcium Carbonate .. ... 2 units
All peat samples referred to above have a 57.6 wt % moisture content. Determination of the
moisture content of the peat is an important factor in formulating a growing medium since the
percentage of oven dry peat affects the buffering capacity of the plant growing medium.
The components of the mixture may be varied or altered as required. Compositions can be
produced to provide a whole range of pH values.
The container itself is preferably of a size suitable for fitting into standard household aquaria.
For example, the size of the container can range from 8 inches long by 4 inches wide and + inch thick to 4 inches long by 4 inches wide, and again < inch thick.
In order to use the above described container for growing aquatic plants, holes are cut in the
wall of the bag 1. Aquatic plants 3 are then planted in the growing medium 2 through the
holes. The whole assembly is then submerged in water in an aquarium and the bag 1 is buried
under the aquarium gravel 4 leaving the plants 3 protruding. The external seams assist in
holding the bag submerged since they increase the surface area which can be buried under the
gravel. The pH of the growing medium 2 is complementary to the pH of the water in the aquarium, and the aquatic plants 3 are selected in accordance with these pH conditions.
In order to sell the containers, a retailer may stock a range of containers containing various growing media covering a wide pH range, for example some containing acid, some containing neutral and some containing alkaline growing media. Alternatively in for example a hard water area, it may only be necessary to stock containers containing alkaline growing media. The containers will be marked for example with a coloured strip to indicate the pH of the growing medium it contains. The customer will then be able to select the particular container which complements the water in his aquarium. With the aid of information supplied for example in the form of a wall chart, he will be able to ascertain which plants will grow successfully in that particular environment.
The above described plant growing system is advantageous in that it provides an optimum pH growth media for aquatic plants. A further advantage lies in the fact that the growing media is contained in a substantially enclosed environment (i.e. the bag) and so is not subjected to the harmful water movement caused by the aquarium filtration system.
