View Full Version : HOB filter for manits

most of the tanks I had were drilled or had a false wall to hide the filter/cleaning stuff, how many of you run HOB filters instead of sumps? do you run oversized HOB filter to help keep everything clean?

Its not about size. It is not difficult to get a strong cycle on a tank as so much of the bacteria lives on the liverock and sand anyway.

Nitrates are nitrates, and food will break down into nitrates whether they get sucked into the filter or it breaks down on the sand. Just rinse the filter regularly with tank water and you should be golden.

You should have a powerhead for oxygen and I would certainly recommend a protein skimmer for any of the more sensitive mantis

most of my reef tanks have been drilled and last two mantis tanks were 29biocubes just always heard bad stuff about hob filters like they are nitrate farms but i have never used them so really have no idea. was thinking of getting a 40gal and setting up a peacock tank again and thought about getting a hob for like a 75gal to extra clean, instead of drilling it.

I would definitely opt for a HOB protein skimmer over an HOB filter, especially for a Peacock. Big difference in water quality IMO.

Well HOB filters do not concern themselves with nitrate removal period. It is really just a filter pad to facilitate the nitrogen cycle.

One really nice thing about an HOB filter is that you can easily remove the filter every 3 days or so and give it a good rinse! This will significantly reduce nitrate production. They collect a lot of gunk for you in one convenient place that you can easily access.

But if you are going for a peacock or god forbid, a Havanensis, get a SKIMMER. Those guys are sensitive.

People seem to have good luck with the Reef Octopus BH-1000 and aquamaxx HOB skimmers. Really depends on what size tank you have. Not too terribly many upgrades are possible for a device as simple as a skimmer. You just need a good pump and preferably a large enough body for good mixing of air/water (i.e. smaller skimmers aren't usually as effective as larger models).
