Specialized nutrition designed for vibrant colors and healthy growth, these floating granules feature a unique ring and core structure enriched with high levels of pigment-dense spirulina and astaxanthin-rich Haematococcus algae. This formulation ensures remarkable color intensity and clear definition within color zones, preventing any yellowing of white patterns while delivering a lustrous sheen and an optimal amino acid balance for superior growth.

Proper nutrition is essential for highlighting the stunning colors of Koi. The significant inclusion of spirulina microalgae in this feed promotes color saturation and enhancement, alongside clear demarcation of color zones. White areas remain bright without an unsightly yellow tint. Spirulina boasts over 50% protein content, providing all essential amino acids along with numerous unsaturated fatty acids. Furthermore, the algae are rich in various vitamins and minerals. Astaxanthin, in particular, enhances coloration, especially in red regions. This pigment, akin to vitamins, bolsters the immune system, acts as an antioxidant, and supports reproductive health. Only the natural, highly bioavailable form of astaxanthin is utilized in sera feed, with Haematococcus algae being the primary source (60.5 mg of astaxanthin per kg of feed). Additionally, ingredients such as krill and spirulina contribute to the supply of astaxanthin and other vital pigments.

Koi Professional Color is composed of two essential parts: a feeding ring and a feeding core. This innovative design is achieved through a specialized co-extrusion manufacturing process that allows for the combination of differently processed components. The ring is made from high-quality natural ingredients, including spirulina and Haematococcus, ensuring both outstanding colors and adequate nutrition. The core includes essential vitamins, minerals, and trace elements to promote healthy growth and a robust immune system. This colored feed can be offered year-round when the water temperature exceeds 8°C. It serves as a complete diet for all Koi.

a quiet life???
This is a short story collection like Sir Arthur Conan Doyle and Agatha Christie have for Holmes and Poirot/Marple. The characters remind me of the Phryne Fisher books. There are four stories in Book 1 A Quiet Life in the Country Lady Emily Hartcastle and her maid Miss Florence Armstrong are enjoying some time in the country in the small town of Littleton Cotterell when they come across a dead body. They find out that it is Frank Pickering, a local man and it is thought that he committed suicide. But investigating, it seems that he has been murdered. Who did it and why? The Circus comes to town Lady Hartcastle meets an old friend George who is the manager who for a circus that has come to town. The next day, the juggler Hubert 'Huey' Parving is found dead mawled in a cage and then others began to die. Who is behind this? The Case of the Missing Case Lady Hartcastle and Flo go to the engagement party of young Clarissa Farley-Strouds. The next day, Nelson Holloway, the trumpet player with that night's entertainment - Roland Richman's Ragtime Revue. Who killed him? As they investigate, the clues lead them to possible cursed stolen jewel. The Half-Death of Gunther Ehrlichmann Florence recounts her life before and after meeting Lady and Lord Hartcastle as she and Lady Hartcastle along with Lady Hartcastle's brother hunt down a killer. Each story is tied into the other, but exciting! Must read!

Fun Seeing Where it All Begins for the Fantastic Amateur Detecting Duo
Format: Audiobook
I started with book three in this series, progressed forward, and finally took the opportunity to go back and get the first book in the series. The whimsical, cozy mystery paired with historical Edwardian setting was light and whimsical. Actually, when I started listening, I realized that the first book introduced Lady Hardcastle and her ladies' maid, Florence Armstrong along with their new home and the other regular characters, in such a way that it didn't feel like the first book so much as the first of the stories that had been recorded. There are hints of their unusual, dangerous work abroad and no big explanation why the pair happened to be set upon 'a quiet life in the country' or why Lady Hardcastle and Florence have a relationship that is nearly family rather than an employer and servant from separate classes. The author trickles out the details and the reader/listener must catch them and piece them together as they go. Because I had experienced later books, those pieces stuck out easily to me. The meeting with Inspector Sunderland and the local villagers and neighborhood was fun. There are two murder mysteries that have interesting crossover people and facts. One seems to involve a dead man from the village cricket team whose death was meant to appear like a suicide and then later, the death of a rag-time band trumpeteer that played at the engagement party of the local squire's daughter. A theft is tossed in for good measure. I figured out one of the murders and part of the theft and the second murder, but the ultimate solution took me by surprise. Loved seeing the intrepid Flo able to get in some of her martial arts ability and spend time trailing along as they teased out the solution along side Inspector Sunderland. Elizabeth Knowelden is an absolute gem of a narrator and the voice of this series for me. She laid out the Edwardian country village world, the variety of genders and accents, and kept the pace and tone for this series just right. All in all, I thought this first entry was as fabulous as the later books and do not hesitate to put it out there as a good bet for historical cozy mystery lovers.

No white residue
Size: 3.4 Fl Oz (Pack of 1)
I put this sunscreen on immediately after it was delivered. It smells so good & goes on smoothly without any white residue. It seems to protect the skin, but then again I put some on every hour on the hour and didn't have any issues. I will be reordering. I wish this was on subscribe and save, but will continue to purchase.
