Premium quality liquid filter medium

Effectively breaks down leftover food, ammonium, and nitrite through biological processes.

Offers a settling space for beneficial purification bacteria, creating a biologically active living environment.

Toxic substances like ammonium and nitrite are constantly produced in aquarium water. With sera bio nitrivec, a product of sera biotechnology, millions of purification bacteria are included to quickly and reliably establish a stable biological balance, continuously breaking down these harmful substances.

The added mineral volcanic rock helps eliminate pollutants, effectively binds cloudiness, and provides an ideal settling area for the purification bacteria. This ensures healthy, clear, and biologically active water.

When used in combination with sera aquatan, fish can be added just 24 hours after treatment!

All around helpful---worth the money!
Format: Paperback
This guide has been most helpful for all the folks I help prepare for the iTEP test! It gives insight into what each section of the test is looking for along with examples and great tips about actually TAKING the test. In the Writing and Speaking sections, it also gives sample scores and comments from the Master Grader which is very helpful too.

Comprehensive, clear and coherent!
Format: Paperback
The iTEP Practice Guide combines a no-nonsense approach to the specific iTEP tests and at the same time offers exercises that task the student with what they need to know. Exercises not only serve the purpose of scoring well, but the overall approach is communicative competence. We use the text in our group and one-to-one classes with very positive--and lasting--results.

No recomiendo
Format: Paperback
Muy malo, no vine completo, además se demoró mucho más de lo que decía al momento de comprarlo. Solo aplazaban la fecha de entrega sin consultar cómo afectaba al cliente. Yo tuve que presentar el examen sin el libro, porque no llegó en la fecha que decía al comprarlo y después se cambió 3 veces la fecha, casi cumpliendo el mes.
