Red Sea Marine Care Test Kit (pH, Alk, NH4, NO2, and NO3)

Red Sea Marine Care Test Kit is used to monitor the nitrate, nitrite, ammonia, pH, and alkalinity levels in marine aquariums to ensure optimal water conditions for aquatic organisms.

The Red Sea Marine Care Test kit includes all of the main kits you need to run a healthy marine aquarium, allowing you to easily monitor the nitrate, nitrite, ammonia, pH, and alkalinity levels.

Buying all of the kits in one handy box saves you money, and because they're from Red Sea, you can rest assured that they'll be just right for your marine aquarium or reef so you can keep the water in tip-top condition.

The easy-to-use tests come with simple instructions and color charts so you can accurately monitor all the important parameters during the biological maturation period of marine and reef aquariums and for the ongoing maintenance in any saltwater aquarium.

Introduction to pH & Alkalinity:

The pH is a very important parameter in the biology of aquatic organisms. It is a measure of the acidity or basicity of the water. The scale runs from zero to 14. Zero is the most acidic, 7 is neutral and 14 is the most basic. A change of 1 pH unit, for example from 7 to 6, means that the water gets 10 times more acidic.

Due to its chemistry, salt water is able to absorb a certain amount of acidic matter without a resulting change in pH. The substances in the water that do this are called buffers. The ability of water to withstand changes in pH is called buffer capacity. Based on a method of measuring buffer capacity it is referred to as the alkalinity of seawater. In some of the literature, alkalinity is termed Carbonate Hardness or KH Carbonate Buffer. This is exactly the same measurement as is measured in the Alkalinity Mini-Lab Test.

pH and Alkalinity

The pH of natural seawater varies geographically in the world's oceans between 8.1 and 8.4. On a local scale, the pH is however remarkably stable. This is due to dissolved buffers (mainly bicarbonates), which prevent pH changes. Because of the enormous volume of the ocean, a nearly inexhaustible stock of buffers is present: the sea can take up large amounts of acids, without a noticeable change in pH.

Compared to the sea the volume of a marine aquarium is very limited and therefore the alkalinity is also limited. As fish produce acid waste products and as the buffering substances are used up by calcareous algae and invertebrates, the buffer capacity may become so low that the pH could suddenly fall. This would be very dangerous to all organisms in the aquarium.

The alkalinity is measured in so-called mil-equivalents of alkaline substances (for example sodium bicarbonate) per liter. These alkaline substances have the power to prevent pH drops. The alkalinity of natural seawater is approximately 2.5 mil-equivalents per liter. This level should also be maintained in the marine aquarium.

A common symptom of an unsuitable pH is pH stress. Especially in the marine aquarium, unsuitable pH values are very stressful to fish and increase the chance of the fish being susceptible to disease (marine white spot).

Ammonia (NH4)

This top-quality marine test kit includes three bottles of ammonia testing reagent, a handy syringe, and a glass vial in which to run the tests. The kit measures the total ammonia for marine aquariums. Any reading of 0.25ppm or above of total ammonia indicates a level of toxic ammonia which will have a negative effect on the fish.

Nitrite and Nitrate (NO2/NO3)

The Nitrate Cycle: Ammonia, produced by fish as a waste product is oxidized by aerobic bacteria in the biological filter: first to Nitrite (NO2-) and further to Nitrate (NO3-). In nature a complete nitrogen cycle exists, where plants utilize Nitrate as a food source, thus maintaining the very low Nitrate level found in unpolluted water. In the aquarium, we create a one-way system rather than a nutrient cycle.

The Red Sea Nitrate and Nitrite test allows you to test the nitrate and nitrite levels within your marine aquarium, making the water just right for your fish and inverts.

This high-quality kit is aimed specifically at marine fish keepers and reef aquarium owners and includes two bottles of reagent, a syringe, and a glass vial. The kit measures the total nitrate and nitrite for marine aquariums for effective water quality management.

STRONG AS A MONSTER (albeit a cute one)
Color: Large - Billy the Beast Monster, Color: Large - Billy the Beast Monster
My aggressive chewer ate the adorable monster's ear off on the first day, but who cares? The body of the monster has been indestructible so far (one week). My 7 month old pup cbews it for a good 10-15 minutes at a time several times per day. Great quality product and outlasting all the other toys I bought (which she destroyed in 10 minutes - even the ones rated "Level 4 toughness" from Walmart. I think it's hilarious in my photo that the monster's expression perfectly shows his disappointment about missing an ear, LOL.

King has met his match.
Color: Large - Billy the Beast Monster
I received my dog's toy this evening when I place the toy on the ground my dog King went crazy. He is a one-year-old Pitbull and love to tackle any toy he believes he can't take down, but Mr King has met his match with this toy. He was using all of his bite force to demolish the toy but the toy actually has worn him out. He ran around my yard for about 30 minutes with the toy in his mouth producing the squeaking sound from the toy as well. Hold up the toy is totally filthy with dirt almost covering the entire green and yellow belly of the toy. I have brought king mini toys in the last couple of months and this is the best toy that holds up to his energy level. I tried to retrieve the toy and place it in his dog house because it is far beyond his bedtime, but he wanted to play catch me if You can with my new toy. This is a great toy for those big energetic dogs that love to take their aggression out on maybe some furniture or perhaps that favorite shoe you do not want them to chew on. I am totally sold on this toy I brought from the seller who placed the items on the Amazon site. I plan on purchasing a another toy from the buyer to keep King energy at a low level if I can. I just checked on my dog and he actually has taken the toy with him inside of his dog house and now the toy is snugged under his left paw. I'm one of those smart owners I'm not going to even try to take it from him tonight but hopefully in the next week I can sneak it from him and it may be perhaps wash it. I did this item AA Plus

Cute, but not Maligator-proof!
Color: Small - Towering Timmy Monster, Color: Small - Towering Timmy Monster
Fun toy while it lasts. My Belgian Malinois made quick work of this little guy but still enjoys playing with its carcass. Bite Force* but not taking into account the bite force of a Mali-gator!

Puppy Love
Color: Small - the Goofy Monster, Color: Small - the Goofy Monster
Short backstory.... My daughter moved in with her 3 dogs recently and brought her dogs toys. Over the course of the last 3 months, my dogs have managed to steal every last toy they could find. fast forward to purchasing this Blue Monster. It came today and was immediately grabbed by one of my dogs. She refused to give it up even for her favorite ball. Ten minutes later another dog had the baby monster and was not giving it up!!!! (think growling) I thought that I would put the monster up for the night to allow for some sleep but it felt like it had been soaked in slobber ( I am sure I saw it drip ;) ). My dogs seems to think this little blue monster is their one true love. Now for some facts. 1. Baby monster is quite small in comparison to my other Bite Force dog toys. It is not too small for my dogs but it is definitely not a size I would give to my daughters Pit that thinks she is a vacuum. 2. Squeaker lasted about 2 minutes before my dog drool invaded it. Currently no squeaky sounds can be heard...just slightly squishy sounds 3. No holes despite my dogs trying. There has been constant chewing (by Standard Poodles) on this little guy for the last 5 hours and not one little open area. Trust me this is a huge accomplishment. Stuffies last 10 seconds in this house. If you need a toy that will last longer than most I highly recommend Bite Force. The are designed for tough chewers and take a beating

My raptor GSP destroyed this dino toy
Color: Medium - Dilophosaurus, Color: Medium - Dilophosaurus
My dog ripped this toy apart faster than the trex did the lawyer in Jurassic Park. 2 hours! Arm was ripped off, stuffing pulled out methodically over the next to days. Now it is a gutless husk. The metor was kinder to the og dinos than my gsp was to this. Sorry Bite Force. Open to product sampling tho!
