![]() ![]() How is the flow through cross sectional area of Tidal compared with AC.The results of years of technological development and evolution, the Seachem Tidal 110 Power Filter is the new and improved version of the traditional hang-on back filters that aquarium owners love and trust. The media will get clogged and popped in the first inch of cross section before the full volume. What is more important are the media volume for biological filtration, and cross sectional area for mechanical. In fact, I retrofit smaller impeller in my Penguin HOBs to enhance efficiency and prolong filter cleaning. If high gph is what you need, get a circulation pump. Too high gph without sufficient media will under perform, for instance, you don’t want to run a sponge filter with a power head which will clog up at no time. High gph is not a key factor to measure HOB performance, but it’s a marketable number customers pay attention to. How often and easy to take the Tidal motor apart to clean the impeller is a question for long term use. From my experience using power head, all impeller will eventually gunk up and need cleaning. AC is a reliable self primer in power outage, Whisper is worst, and Marineland Penguin is fair. The frequency for required cleaning varies with bio load, brand and model. AC and all HOBs will self primp if the box is not empty and the impeller is not gunk out. Self priming in power interruption is an important safety factor though. Is it really quieter? Self priming in empty box isn’t a big deal as you only need to fill up the box the first time. I bought one and returned, because the smaller model I bought couldnt fit in my tank rim, so I don’t know it’s long term performance. One stand out feature of Tidal is that the motor is submerged inside the tank, so it is self priming even if the box is empty, and marketed to be quieter. How deep is the Tidal box? One eye scoring thing about AC is that the box is very deep, meaning that you have to sit the tank farther away from the wall. Of all the HOB filters there are, I definitely think these two are the best. What I like more about seachem is that it can hold more media, you can adjust the intake tube (which will help if you have a shorter or taller tank), and the pump is self priming. ![]() ![]() Verdict: I think the seachem tidal is better, it just has a lot of things the aquaclear doesn't, but to be clear, I love both filters. The pump is self priming, just plug in and it works (especially useful if you lose power a lot) +1 No indicator to indicate if it is cloggedĪdjustable intake tube (can adjust length) +.5Ĭannot adjust the length of the intake tube Has an indicator to indicate if filter is clogged +.5 $74.14 (on Amazon) +1 for being cheaper (though it's not that much of a difference) Has a heater clip (not a very big deal so I'll give. Holds more media (I had two pounds of biomax and some matrix that came with the filter in there, all fit no problem) +1ĭoesn't hold as much media (I got about 1 bag of biomax to fit, I also didn't add in the carbon to try to give more room) No surface skimmer, can be a pro or con so I won't add anything Has a surface skimmer (pro or con, depending on whether or not you have duckweed in your tank and if you like having your water level lower) ![]()
