Plants beautiful - Be careful when prawns and crabs

The plants are all very nice. No brown spots. Also had one of each kind a neat collar as a set. This means you really get something for his money. The moss ball has about 5 centimeters in diameter.

Who only has fish in the aquarium, the plants used immediately without hesitation and look forward to.

However, if you crustaceans ie crabs, crayfish and shrimp in particular maintains the pool of be warned.
The delivery is indeed in a note of a two-day watering the plants recommended for shrimp. Unfortunately, this is indicative grossly understated.
For me the plants for shrimp / cancer - pool determined, so I watered them three days. A few hours after using the started the first shrimp to totter. A little later, the CPO's.
An immediate change of water, the catch out of most animals (all you never caught), water purifier, etc. saved most animals life. Nevertheless, I have to complain about some failures.

I erhilet the plant in early August. It's been almost 4 weeks. I make a daily change of water and yet I always find overlooked shrimp lying in some corner of the page or the back and batting only to himself. After reacting to recover most within one day.

Reason for the failures is that the plants are heavily polluted with fertilizers and pesticides. Invertebrates - such as snails and the like - are of course not desirable in the breed crops and so do not skimp on the chemistry.
However crustaceans are also invertebrates and are also killed by the toxins.
Normally, these poisons washed within a few days out from the plants. Something as stubborn as here I've never seen.

Conclusion:
For fish absolutely unproblematic and beautiful plants.
For crustaceans without watering absolutely deadly. After nearly four weeks, my CPO's now seem cope with the water to come. Shrimp still can not survive in said pool.
