New Pond



Foundation of a new pond or water change means filling up with clean, fresh water. You can
use tap water or well water but both of them have to be conditioned and adjusted to
biotope needs, all harmful substances such as chloride, heavy metals must be removed, all
basic parameters have to be stabilized (pH, temporary harness), vaccinated with bacterial
flora and protected from algae growth. Self-cleaning mechanisms and ecological processes
can only function properly in sufficiently hard and buffered pond water (pH 7.5 – 8.5,
temporary hardness over 5°). Fluctuation of pH value may cause reduction of variety of
species and also mass growth of some kinds of algae. PH fluctuation may also have negative
influence on zooplankton – an enemy of algae. These are main factors upsetting proper
functionality of garden reservoirs.

Next steps will help you in selection of proper agents to keep clean and healthy water in
your pond.

In case your pond isn’t supplied with filtration system it is necessary to create large
regeneration zone – shallow water zone with numerous plants which have filtrating features.
Additionally installation of circulating pump or airing pump is highly recommended.


You can use TeichStarter to condition water (tap water, rain water or well water) up to the level which complies with biotope of pond water; to bond harmful substances, chloride or heavy metals which can have negative influence on pond life, also to increase temporary hardness (pH value doesn’t fluctuate).

Hardness (pH value doesn’t fluctuate). Improper parameters of water lead to increase of
ammonia and nitrite toxicity. This is very hazardous for all water species and finally can lead
to disturbances in food chain, various fish diseases (thrush), mass growth of algae, sludge
increase and finally degradation of water environment. This agent creates perfect life
conditions for all pond occupants and proper climate for lively shinny fishes.



It is necessary to use agents which absorb phosphates, ammonia and heavy metals to avoid
algae growth.
Tap water contains 6.5 mg/L of phosphate which protects pipes and instruments from
corrosion and lime settling. Well water may contain even up to 4 times more phosphates.
Water biologically free from germs gives filamentous algae and green algae maximum
advantage during absorbing nutritious substances (food, pollens, sludge, etc).
In case the concentration of phosphate (PO43) is greater than 0.035mg/L mass growth of
algae can increase. 1 kg of algae can arise from 0,1g of phosphates!!!

Purified zeolite or ZeoSpeed are recommended agents which bond phosphates.

ZeoSpeed is a multi-ply, renewable and highly efficient zeolite. Bonds ammonia and
phosphates; may be used in filter or directly in pond water. Each zeolite has limited capacity
and usually works for approx. 6-8 weeks. Then needs to be changed or regenerated with

PhosLock AlgenStopp is strongest bonding agent in the world. Continuously reduces
phosphate volume (main algae nutrition) to the level below 0,035mg/L thus reduces mass
algae growth. It has to be applied on a regular basis every 6 weeks.



In both cases when filtration system is installed (filter, UVC lamp and filtrating pump) or is
not installed, biological life of the pond may be made alive by using of bacterial starters.
Those agents help in creation of bacterial flora which is essential in biological cleaning
process. Cultures of bacteria which are taking part in a self cleaning process can appear in a
pond after 6-8 weeks. Bacteria starter shortens this period to 1 week.

Pond without filtrating system

In case of ponds not equipped in filtrating system it is highly recommended to use Dr.
Roth’s®Teichklar. This agent contains wide variety of microorganisms which enrich biological
life in the pond. This increases biological capacity of decomposition of organic substances
polluting pond water and slime. This agent also reduces algae blooming and prevents
putrefaction and reduces creation of harmful gases. Should be applied regularly every 4
weeks. BioBooster® should also be applied at spring start up and is responsible for
settlement of highly active bacteria cultures thus quickly removes toxic concentration of


Pond with filtrating system

BioBooster takes care of settlement of highly active bacteria cultures thus quickly removes
toxic concentration of nitrogen from both pond and filters. That helps to create bacterial
flora – essential in biological filtration process, reduces activation time of pond filters. At the
same time it is recommended to apply FilterStarterBakterien to activate bacterial flora in a
filter. Properly selected microorganisms immediately activate biological cleaning mechanism
in pond water.


Bacteria can only be strained if average water temperature is over 8°C. Before applying the
agent it is necessary to switch of the UVC lamp. Lamp can be again switched on after 48 hrs.


Mass growth of algae in water reservoirs is the most common problem. It is very difficult and
time consuming to control its growth. At the moment there are over 100 000 known algae.
The most common are: suspension algae, cyanobacteria, flagellates and filamentous algae.
Algae are not only ugly but may also produce harmful toxic substances being dangerous for
fishes. Researches prove that metabolic poisons of cyanobacteria may be dangerous for
people – can lead to various allergies, eczema as far as serious nerves damages. Algae
removal is onerous so it’s much easier to fight with algae at the earliest stage. Anti-algae
agents and phosphate bonding agents should be applied. Unfortunately most of available
anti-algae agents are only effective on certain kind of algae; they are often harmful for fishes
and plants; they only reduce algae but not protect against them. Most of agents are not
effective in alkaline water (pH > 8.5°)

AlgoSoll® is the only available agent which is effective on all kinds of algae and additionally
protects reservoir against its growth.


AlgoSol® fights against all kinds of algae (green algae, filamentous algae, flagellates) and if
applied regularly effectively protects your pond against its growth. Active substances
contained in AlgoSol® stop sunlight which is necessary for photosynthesis (SpectroSorp)
process on one hand and from the other hand allow carrying out essential biological
regulation process and metabolism. Algae are starved. This agent may be applied at least
24hrs after or before application of TeichFit.
