This product is designed to measure the concentration of magnesium in a marine aquarium and includes a spare cartridge for reagent 3.

Warning! Reagent 1 contains sodium hydroxide, which can cause serious burns. Keep this reagent securely stored and out of reach of children. Always wear protective gloves when handling. If the substance comes into contact with your eyes, rinse immediately with water and seek medical attention. If you experience nausea, consult a doctor and bring this manual with you.

A proper magnesium concentration is essential for the health of marine invertebrates and algae. A prime example is the red calcareous algae, which require substantial amounts of magnesium to form their skeletons. Natural seawater typically has around 1300 mg/l of magnesium. To create optimal conditions in your marine aquarium, it's crucial to maintain this concentration. The Sera magnesium test allows you to quickly and easily assess the magnesium level in your aquarium. You can also effectively boost magnesium levels using Sera magnesium plus.

Additionally, magnesium levels can be raised with Sera marin COMPONENT 6 magnesium. The amount of reagent needed will depend on the calcium levels in the water you are testing.

Store in a cool, dark place!

Instructions for Use:

In a marine water aquarium, maintaining an optimal magnesium level is vital for the thriving of invertebrates and decorative algae. Red calcareous algae are a great example, as they require high magnesium levels for their skeletal structure. Natural marine water contains around 1,300 mg/l, which should also be replicated in your aquarium for ideal conditions. The Sera magnesium-Test enables you to monitor your aquarium’s magnesium levels swiftly and efficiently. If you have prior testing experience with the Sera calcium-Test, this will be even easier for you. You can easily enhance the magnesium level in your marine water aquarium by using Sera marin COMPONENT 6 magnesium.

Directions for use: Shake the reagent bottles well before use! Avoid letting the tested water come into contact with aquarium or pond water!

  1. Rinse the measurement vial several times with the water you wish to test, then empty it. Dry the outside of the vial.
  2. Rinse the syringe multiple times with the water to be tested, then use it to fill the vial with 2 ml of this water.
  3. Add 6 drops of reagent 1 and shake the vial until the liquid is evenly mixed. Any cloudiness that appears will not affect the test.
  4. Add one level measuring spoon (provided in the kit) of reagent 2 to the vial and gently swirl (do not shake) until the powder has dissolved.
  5. Gradually add reagent 3 drop by drop while counting them. After every 5 drops, release pressure on the bottle to allow air to enter. Shake the vial after each drop until the color shifts from pink to blue (not violet) and remains stable for at least 30 seconds while you gently whirl the vial occasionally. Note the number of drops used.
  6. Empty and thoroughly rinse the measurement vial with tap water, then rinse it several times with the water to be tested and empty it again. Dry the outside of the vial.
  7. Use the syringe to take up 2 ml of the water to be tested and fill the vial.
  8. Add 6 drops of reagent 4 and shake the vial until the liquid is evenly mixed. Any cloudiness that appears will not affect the test.
  9. Add one level measuring spoon (included in the kit) of reagent 5 to the vial and gently swirl (do not shake) until the powder has dissolved.
  10. Add reagent 3 drop by drop while counting the drops, releasing pressure on the bottle after every 5 drops to allow air to be drawn in. Shake the vial after each drop until the color changes from red to green and remains stable for at least 30 seconds while whirling the vial occasionally. Note – you will require significantly more drops for this measurement compared to the first measurement!
  11. To find the magnesium level, subtract the number of drops used for the first measurement from the number of drops used for the second measurement. Multiply the remaining number of drops by 60 to calculate the magnesium level in mg/l. For example, if the first measurement used 4 drops and the second used 24 drops, subtracting gives you 20 drops. Multiplying 20 drops by 60 results in a magnesium level of 1,200 mg/l.
  12. Cleaning: Thoroughly clean the vial and syringe with tap water before and after each test. Close the reagent bottles immediately after use and do not switch caps. Store at room temperature and away from light. This product is intended for testing ornamental fish aquariums and pond water only.

Niz !!!
Format: Kindle
First, let me say that I love both of these authors. I have been hooked by both ever since I discovered their writings, and I follow their social media groups closely. This book did not disappoint. Sure, there are several questions that I have, a couple of times I went huh (which I won't get into because I do not want to offer any spoilers) and I hated the cliff hanger lol, but I cannot lie and say I didn't love the book, because I did. The twist on angels was new and fresh, even though that is part of my questions. The beginning and ending were the better parts, the middle was needed but sorta bogged a little. Kieran was confusing but relatable. Niz is BY FAR the best character of the book, love NIZ. For me, Bastian is a close second, always loved the crazy ones. The other men were good, but Steele gets on my nerves and as of right now, IMO, he doesn't belong, but we will see how that goes. I have lots of questions, but this was an excellent start to a new series and I cannot wait for the next book. Highly recommend

fallen destiny? more like destined to fall in love
Format: Kindle
Kieran is an angel, but she doesn't have an affinity. Nothing angers her father more. If she doesn't find an affinity soon she will be cast to earth & have her wings removed. But she has the choice to become a fallen angel, wings turn black, & live her life on edge. Towards the end of the book things start to make sense. Gabe’s nickname for Kieran, Steele’a hatred, Bastian’s belief that Kieran is powerful. This book ended literally during a war? As one of her friends was injured, and admitted a bit secret? Talk about cliff hanger. The next book comes out August 5th.

Well holy moly!
Format: Kindle
Holy moly that story definitely had me hooked! Kieran was definitely a character that I immediately adored. She has obviously had to deal with a butt load of too high expectations from her father (who is 🤬).. She has been helpless when it came to finding out her affinity with so many years of no answers & perceived failure. When Ronan, gives her a small inkling of hope that she be a Beast Tamer, she jumps into it. But again she doesn’t seem to fit. But when she runs into Gabe again, she ends up helping him & rethinking her life in Alfemir. And when the opportunity comes she decides leaving is the best option. But when Ronan demands he comes with her & then the random appearance of Bastian, she is feeling very overwhelmed. After she chooses to fall with them, they land on earth exactly where Gabe is located only to run into Steele who is a person that I was finding hard to like. After training, she eventually finds out she does have an affinity & it’s one that no longer exist & is incredibly powerful but also has a prophecy attached to it. I feel incredibly bad for her on she learns about the prophecy & Steele’s connection with it too. But that ending, with the battle scene & Niz….yeah definitely was not expecting that but hello I am all here for it too! Absolutely amazing start of a series & I for sure will be waiting for the next one to come out. Amazing job!

So good!
Format: Kindle
Wings of Stars was a fantastic first book to a new series. It grabbed me in its clutches within the first chapter and kept ahold of me. This new world of M Sinclair and RL Caulder’s is all about angels and mythical creatures. It’s full of drama from all points. From Kieran’s awful home life to keeping the stars alive and everything in between. Kieran is our FMC and despite everything she keeps her spirit and defiance. Keeping to their norm, there is a group of guys for our FMC but they definitely aren’t established yet, and not fully cemented yet into being a group rather than her choosing between them. Ronan is so sweet and gives off Daddy vibes Gabe is also sweet and wants the best of everything for Kieran and will defend her against anyone Bastian is slightly unhinged but I loved him immediately Steele is a jerk… just as you find redeeming qualities, he screws up again… but yet I still want him to redeem himself. There’s another one… but if I gave his name I would be spoiling a plot twist so you will just have to find out yourself… but you’ll love him as much as I do. This is a slow burn but the little bit of spice we do get is hot, especially with the dirty talk.

Angels and the Fallen — Breathtaking Start
Format: Kindle
This book was EVERYTHING I expected it to be and more. Leave to R.L. Caulder and M. Sinclair to give us yet another amazing book! Kieran and her guys hooked me from the very beginning and did not let go. Found family is one of my favorite tropes and it was done so well in this book. Couple that along with an FMC trying to find her place in the world and I was practically drooling over this book. The world building, the conflict, the wyverin sidekick — it all was done so well that it felt fresh and real. Each love interest felt real and unique in their own ways. I felt connected to each one and like they were truly different people. I love that so much in a book and these two authors never miss with their love interests. Multi POV, Reverse harem, who did this to you, and a magical world highlighting the angels and the fallen. This book has everything and it does it so well. Big thank you to R.L. Caulder and M. Sinclair for the arc copy! I cannot wait for book 2!
