The myAQUA 1900 is a new streamlined version of an all-in-one reverse osmosis unit for high level purification of water for aquarium use. Branded by ARKA Aquatics the Chinese made myAQUA 1900 promises a high rate of water production with simple plug and play installation and lots of fancy features and accessories built right inside the R.O. unit.
Before we dive into the various ways the myAQUA 1900 promises a great experience the real defining feature is its incredible water output which tops out at 1,900 liters or 501 gallons per day thanks to the built-in automatic booster pump. The increase in water pressure is key to boosting the water output which will vary with the temperature of the feed water but can also be very efficient in water usage with a pure to waste water ratio as low as 1:1 or up to 1:1.5, so a lot less waste water than a typical unboosted R.O. setup.
Myaqua 1900的另一个特征是它使用了一种新的机械，碳和膜墨盒的格式，这些格式只需将锁定锁定到位而无需任何诸如罐扳手之类的工具。尽管这些墨盒可能方便使用，但它们并不昂贵，但是它们是专有的，并且在Arka建立了良好的欧洲分销范围之外，将更具挑战性。
我们发现关于Myaqua 1900的困惑的一个方面是，替代前滤器，碳和树脂墨盒的出售和没有各自的房屋，价格为15欧元。虽然我们发现房屋本身很容易在使用之前用一些力量打开，但在通过它们运行了几百加仑之后，即使使用提供的扳手，住房也变得更加困难。
购买完整的墨盒和住房可能会有一些方便，但是您不需要更换住房，因为您无法自行打开它。R.O.单元平台doesn’t require replacement housings unless it becomes damaged somehow but we fear this dual option might lead to excessive plastic waste if users aren’t made aware of the ‘Refill’ option.
Myaqua 1900补充额的价格不到20欧元，但一套替换墨盒和the housing costs €90 without the membrane. Before we get to the performance of the semi-permeable membrane we have to mention that there is no obvious difference in the specifications of the C1 and C2 carbon cartridges which are split into a solid carbon block for the primary C1 carbon cartridge but the second C2 cartridge is unusual simply being filled with granulated carbon, the likes of which users could refill for $1如果这是可以有用的！
奇怪的是，Myaqua 1900的水通过单元的非线性流动路径，第三个腔室是实际R.O.之后的路径中的最后一个腔室。膜。如果有库存，那么C2碳块将在膜之后去除“某物”，但这是ARKA打算让用户放置Deionization Resin Filter Cartridge的位置。说到树脂墨盒，它们也不可重新填充，我们发现两个树脂过滤器补充填充物之间的树脂体积大约有20％的差异。
Myaqua 1900的主要销售功能是其纯净水的巨大输出，其名称为1,900升或500加仑，而本文的先前版本表示我们每天获得约288加仑。在ARKA指示检查气泡或任何可能的泄漏之后，我们怀疑地对进料线进行了视觉检查，实际上发现了一个小泄漏，这导致空气被吸引到设备中！将这种故障的管子替换为每42秒或每天超过500加仑的输出增加一倍以上
While the practicality of the replacement cartridges leave something to be desired we have to commend the booster pump for being noticeably quieter than many we have used before. Despite being mounted to a wall, which we though might amplify the vibrations of the booster pump, the myAQUA runs at an acceptable level of noise for the work that the booster pump is providing.
水产师倾向于认为R.O.单位是绝对的，但膜本身可以达到百分比，这反映在Myaqua 1900的电导率中。当传入的进料水约为380 ppm时，纯净水输出量约为16ppm，但是当原水降低到200的电导率时，ppm所得的纯净水可以像7 ppm一样纯净 - 无需使用最终的抛光DI树脂滤镜。
Some notable defining features of the myAQUA 1900 is that it comes with shut off valve built-in, with automatic back-flushing features available at the touch of a waterproof capacitive sensing button. LED indicators are built into the face of the unit which can sense which canister have unusual pressure and alert the user to any irregularities for trouble shooting or replacement.
当我们第一次看到specifications for the myAQUA 1900我们对一个非常有希望的水净化设置印象深刻。We’re still enjoying the purified water we’re getting from the ARKA myAQUA 1900 and if they succeed in making their proprietary cartridges more widely available, and even a little more user serviceable, we believe that ARKA will have a truly groundbreaking product on their hands.
