来自英国的D＆D正在进入测试套件游戏。他们发布了用于碘，硝酸盐，磷酸盐的测试试剂盒，以及将处理钙，碱度和镁的多测试套件。这些新套件将首先击中英格兰的精美粉丝，最终在没有市场价格的其他市场中传播。有趣的是，硝酸盐测试试剂盒对如何通过首先建议换水（即给定）来减少水族馆中的硝酸盐的建议D-D Bio Pelletproducts that have become increasingly popular. We always love a little cross-selling inside the instructions. Now, titration test kits are nice D&D but where are ourcolorimeters?

D-D Iodine Test Kit
A high quality test kit from D-D to accurately monitor Iodine levels in reef aquaria.
Iodine is considered an essential element for certain biological processes in many marine animals and as such it is paramount to be able to measure and maintain the correct levels in your marine aquarium.
我们建议使用碘工具包的一部分complete testing regime that includes the D-D Phosphate, Multi and Nitrate test kits for best results and to help monitor complete aquarium health and nutrient levels.
Iodine is present in seawater in many different forms, with only some being biologically available for our aquarium inhabitants to utilise. Total iodine concentrations in seawater can vary from one location to another and by depth however the average total iodine concentration of natural seawater is measured at 0.06ppm.
尽管鱼可以通过所吃的食物获得所需的数量，但珊瑚和其他无脊椎动物可以直接从周围的水中以不同的速率从一个物种到下一种物种，而戈尔戈尼亚人，微藻类和宏观藻类是主要消费者。
Iodine levels within marine aquaria should be monitored regularly. Although it is provided at natural levels of 0.06ppm in our H2Ocean Pro+ Reef Salt it becomes depleted quickly and must therefore be maintained by regular supplementation.
This high sensitivity iodine test kit will allow the user to simply and accurately measure levels so that they may be maintained by way of water changes or scheduled dosing.
Accuracy of this test is further improved by the use of a ‘standard’ that is created during each test which sets a known comparison point.
D-D Nitrate Test Kit
A high quality test kit from D-D to accurately monitor Nitrate levels in reef aquaria.
维持低水平的硝酸盐（NO3）和磷酸盐对于在海洋水族馆的成功方面对于鱼类和珊瑚的健康而言至关重要，并且是滋扰藻类生长的食物。
Excessive levels of nitrate give rise to problems controlling algae, maintaining pH, and is a limiting factor in achieving good coloration in corals.
We advise that the Nitrate kit is used as part of a complete testing regime that includes the D-D Phosphate, Multi and Iodine test kits for best results and to help monitor complete aquarium health and nutrient levels.
Natural seawater has an average nitrate concentration of below 0.1ppm with levels below 2ppm being recommended for reef aquariums.
This high sensitivity test kit will allow the user to monitor levels of nitrate measured as NO3, or as total nitrogen N-NO3, within the aquarium so that they may be maintained by way of regular water changes or alternate methods of Nitrate removal or breakdown such as the D-D Bio Pellet products.
The test kit has both a high and a low range scale allowing it to be used to determine the exact level of phosphate in your aquarium.
Specifications
* High Range 0 – 48 ppm NO3
* Low Range 0 – 4 ppm NO3
* The kit includes a reference solution sufficient for 5 tests

Refills are available for this test kit
D-D Phosphate Test Kit
A high sensitivity test kit from D-D to monitor Phosphate levels in reef aquaria.
Maintaining a low level of phosphate (PO4) is crucial for success in marine aquaria. Excessive levels of phosphate can give rise to increased algae populations, act as a calcification inhibitor in stony corals and clams, and is a limiting factor in achieving good coloration in stony corals.
We advise that the Phosphate Kit is used as part of a complete testing regime that includes the D-D Multi, Nitrate and Iodine test kits for best results and to help monitor complete aquarium health and nutrient levels.
天然海水在大约0.005 ppm po4的地表水中平均磷酸盐浓度，推荐水平低于0.1 ppm po4，用于含有石质珊瑚的水族馆，以达到可能为0.25 ppm po4，以供更耐受性物种。低于0.005的水平也是不受欢迎的，但是由于每天喂养过程中添加的磷酸盐量，您不太可能达到零磷酸盐状态。
This high sensitivity test kit will allow the user to monitor levels of phosphate measured as PO4 or P-PO4 within the aquarium so that they may be maintained by way of regular water changes and by way of phosphate removing medias such as Rowaphos.
The test kit has both a high and a low range scale allowing it to be used to determine the exact level of phosphate in your aquarium.
Specifications
* High Range 0 – 5 ppm PO4
*低范围0 - 0.82 ppm PO4
* The kit includes a reference solution sufficient for 5 tests

D-D Multi Test Kit
一个都在一个high quality test kit from D-D to monitor Calcium, Alkalinity and Magnesium in reef aquaria. These three important elements provide calcium and carbonates for Coral growth whilst also providing stable water chemistry when maintained at natural levels.
We advise that the Multi Kit is used as part of a complete testing regime that includes the D-D Phosphate, Nitrate and Iodine test kits for best results and to help monitor complete aquarium health and nutrient levels.
The D-D Multi Test Kit includes liquid tests for the three most commonly tested parameters by marine or reef aquarists, those of calcium, magnesium and alkalinity.
All three parameters have a natural balance relative to each other which should be maintained to provide a healthy environment within your reef aquarium.
This test kit will allow you to monitor the levels of all three parameters that they may be maintained by way of water changes, calcium reactors or scheduled dosing.
We Recommend the use of ‘balanced’ H2Ocean Pro+ salt to help maintain natural levels of these three important ions.
* Calcium
Maintaining the correct calcium (Ca) level is crucial for success in marine aquaria with regard to calcification in stony corals, clams, and some soft corals
Natural seawater has a calcium concentration of between 380-450ppm with an average of 420ppm
* Alkalinity
Maintaining correct alkalinity is crucial for success in marine aquaria as both a factor in calcification in stony corals and clams, and as a buffer to stabilise pH.
Most reef aquariums are recommended to be maintained at 7.0 – 8.4 dKH to allow additional buffering in the system to stabilise the general tendency towards falling pH. Natural seawater has a dkh of around 7.0
* Magnesium
Magnesium is one of the most overlooked elements in the reef aquarium yet maintaining the correct magnesium (Mg) level is crucial for success with regard to calcification in stony corals, coralline algae, clams, and some soft corals.
The correct magnesium level also allows other parameters to be stabilised effectively such as calcium and alkalinity and therefore pH
Natural seawater has a magnesium concentration of approximately 1280ppm however it is recommended that levels within the aquarium should be maintained between 1250 and 1350 depending on the salinity.
