Here’s an excerpt from an out-of-print but still very informative book titled Aquarium Ecology. It discusses why two protein skimmers on the same system will probably not perform as well as one larger skimmer. The translation is a bit rough and a few of the sentences aren’t entirely clear, but it’s still an interesting topic which some may find …
The Tunze Nanostream line of powerheads has a total of five members. The 6015, 6025 and 6045 are the three smallest. These three are non-controllable and are therefore less expensive… all three retail for under $100. Apart from controllability, they have all of the features of all the other Stream and Nanostream powerheads, like high-efficiency, reef-tailored flow …
If you spend much time reading the online forums you’ll know there’s a lof discussion regarding powerheads and other flow devices. A great deal of time is spent trying to weigh the relative merits of one style of pump over another. This is no small task. When a flow device is submerged and powered on, …
With very similar skimming capabilities and only a $20 difference in price, some aquarists have a tough time deciding between the DOC Skimmer 9410 and the DOC Skimmer 9011. From the outside they appear to be from different planets in the protein skimmer universe. The DOC Skimmer 9410 (top left) looks like what most people …
For many, many years the DOC Skimmer 9002 ruled the roost for strong, silent skimming in sub-50 gallon aquariums. With the 9002, ease-of-use, silence and reliability were the core engineering targets- just as they are with all Tunze protein skimmers. But the 9002 had an additional design criteria, its “Nanoness”. We needed it to be …
For small aquariums, a stable osmotic balance is important, because they are particularly sensitive to constantly changing salt concentrations. The Osmolator® nano which was specifically designed for this, is a water level controller with only a single sensor and is equipped with a processor-based controller that protects against overdosing. It is suitable for nano …
