Seltz D控制able AC pumps are Hydor’s latest new product category for use on a wide range of fresh and saltwater aquarium applications. It’s only the second company to develop and release a controllable return pump that usesalternating currentwhich eliminates the need for an AC/DC power supply, reducing both cost, and a point of failure.
如果您想在Koralia之前从螺旋桨泵中流动可观的水流，则必须花大笔钱购买高质量但昂贵的型号。Hydor凭借有能力且负担得起的Korallia Propeller泵线上的礁石场景大肆散步，这正是他们似乎与新的Seltz D泵所采取的角度。
除了缺乏电源外，Hydor的Seltz D泵完全没有传统外观的车身和定制但正常的控制器盒。部分是这种行人设计，它使Seltz d泵无法获得更多的炒作和注意力，但仔细观察Hydor的新泵揭示了一些独特的功能和优势。
First of all, the use of an AC motor does mean that this pump is not as efficient as a comparable DC modelbut，这也意味着它没有与大量直流泵所期望的可怜的流曲线。因此，总而言之，您仍然可以从Seltz D获得大致相似的每瓦流量，因为您必须使用较大的直流泵来满足可控直流泵的现实生活量。
But if we’re keeping it real, the biggest reason to consider the Hydro Setlz D is that it’s the ‘cheapest controllable aquarium pump’notbuilt in China. Compared to the Seltz D 1600 you’ll have to shell out at least $100 more for a brand name return pump and almost $200 more for a controllable DC pump that moves as much water as the biggest Seltz D 3200, it’s not a small difference!
The Hydor Seltz D 1600 is the third pump we’ve tried out on our Red Sea Reefer Peninsula 650 and after more than four months of use it’s definitely our favorite of the bunch. We would go so far as proclaim the Seltz D 1600 the best value pump for Red Sea’s biggest Peninsula Reefer because it pushes an ideal flow rate at full speed – 1,600 gph nominally but drops to a reasonable 1,000+ gph at four feet of head pressure in this setup. We wouldn’t recommend any more flow since the stock filter system isn’t really designed for it (without getting noticeably loud & splashy).
即使没有使用直流泵的正弦波信号技术，该泵本身也令人印象深刻，驾驶员甚至具有指示灯，以提醒用户在泵需要维修时，尽管我们还没有进行。除此之外，该泵还带有明智的进气口滤网，用于浸没使用，以及在内联或置入内线时容易拆卸的工会。
There’s really only one teeny tiny criticism we can make about the Seltz D and that’s the feed timer which is limited to 5 minutes when we’re used to much longer intervals of 10 or more minutes, but to be honest we don’t use it all that much on this particular reef display. If you’re reefing on a budget or just want a controllable pump but don’t need wireless access, programming, or any number of features most of us never use, the Hydor Seltz D is by far the best value in adjustable flow you can get in the aquarium hobby today.
