I need more mechanical filtration for my 150g angelfish tank. The tank currently has two canisters so there is plenty of bio filtration. Between the Aquaclear70 or Penguin 200 HOB Filter, which would you pick? Why? I have both in my possession. Just can’t decide which to use.
I have experience with both and the two have pros and cons. The AC filter is a good filter but when the power is interrupted it will not purge itself and if not noticed the bio media will be dried out.
The Penguin filter is a good filter but cant add extra bio media like with the AC filter but will purge itself when power comes back on after outages.
i know you didn't mention it but i use a tidal 55 for mechanical filtration on my tank. it can handle power outages and has a basket that is easy to stuff with mechanical media and pull out for easy cleaning. just thought i'd mention it. i use a tidal 110 for my bio filtration.
I would use an AC110. Like above they do tend to siphon themselves dry if power is interupted. When I clean mine I do not unplug the filter. I pull the uplift tube and then the media. Rinse both and reassemble. I don't have to remember to plug in after filling the tank.
I was just going to mention looking at Seachem's new Tidal series of filters. Seems to have all the good qualities that fish keepers wants.
Self prime after power outage/maintenance
Surface skimmer
Non cartridge type biological
I use ACs and I am considering changing over.
