Simple Media Setup For Hob Filters


number20121

Alright, Koko wanted me to repost this here in a new topic.

Many people that are new to fish keeping, fall for the replaceable filter cartridges that are sold by the companies that make the filters.

By doing that, you will toss out the majority of your beneficial bacteria every time you replace a cartridge, and so continuously experience cycle bumps, which can lead to health problems for your fish; not to mention the amount of $$ you waste when buying the filter cartridges.

First off: Carbon is not necessary. Only if you need to remove medications from the water, or to remove odor (which usually shouldn't happen in a fish tank, except for a light smell similar to wet soil).

Carbon collects impurities, but if the carbon is "full", these impurities will leech back into the water and can cause health issues.

This is how I set up all my HOB filters:

Get a pack of Marineland Rite Size Undergravel Filter Floss, which costs about $ 6. http://img.photobuck...-filter-pad.jpg (it contains one big, folded up sheet of floss)

Get as many boxes of Fluval Bio Max Ceramic Rings as you can fit in the filter. They are around $ 13 each.

Remove your current media and keep it in a container of tank water.

Cut a piece of filter floss out of the Marineland Rite Size to fit into each of the filters. Only one layer each, and put it in the filter in a way that the water HAS to go through the filter floss first.

Fill the bio rings (rinsed under water first to remove dust) in the available space, as many as you can.

This here is what the end product looks like

In order to keep as many beneficial bacteria as possible, you should additionally add your current filter floss. If you can, remove the carbon. The plastic holders can go in the trash also.

Do NOT rinse your floss in tap water, the chlorine will kill the bacteria.

Then just have your old floss between the new floss and the ceramic rings. The bacteria will start multiplying and spreading out onto your new media.

The floss is what will collect most of the gunk. Rinse/swish/squeeze it in used tank water if they get gunky, and re use. If they are beyond saving, you can replace the floss with a new piece.

The ceramic rings might need occasional gentle swishing in tank water to remove gunk and will last for a long time. :)

You might be right actually. Since I took out the old media too early It could be cycling again...

This is one reason I like to have 2 filters on the tank.... :)

Yeah, never remove the media. You just gently rinse it in tank water or dechlorinated tap water if needed, and put it back in the filter. Just enough to get the majority of gunk off. It does not have to be as clean as new, because that would mean that you removed most of the beneficial bacteria as well.

Very rarely I toss media, and that's usually just a piece of floss that is literally starting to fall apart. I have my media in my tanks for a year now and haven't had to replace anything. :)

If your tank is cycling again, make sure you do the necessary daily water changes!

Absolutely! On both my large tanks I have two filters (in fact on my 55g goldfish tank I have 4 filters, two of them hold plants though but I am sure that there is a decent colony of BBs living on the pothos roots inside these filters). On smaller tanks it is a bit inpractical. I mean, try to fit two filters on a 10 gallon tank :rofl

I'm having a hard time finding this filter floss thing... I ordered this from the amazon link on the first page http://www.amazon.com/gp/aw/d/B000255NO6/ref=mp_s_a_1?qid=1317449832&sr=8-1 , but what I got in the mail looks like animal stuffing, not the solid large sheet... can I still use that? if so, how thick should the layer be? And if I can't use that, what's a good place to order filter floss from? thanks!

You can probably use it too, as it is made for aquarium filters.

The sheets I have are about 1" thick. But they are "fluffy" so you can squeeze them much thinner. You will want it to stay fluffy though, otherwise if it is too solid, it can obstruct the water flow.

I had this happen with the sheet floss when I overstuffed it, and ended up with gallons of water on my carpet because it slowly trickled out of the back of my filter! :yikes

I'm kinda nervous about trying this? From the article above and the posts pages 1-3 I'm a little confused. So do you buy the little ceramic rings and filter floss meaning the blue stuff or is that the white cotton like stuff shown or both? I have two marineland 400 filters on my tank and was wondering how many of those ceramic rings I should put on each side along with the filter floss so I don't overfill it. From the first picture it looks like there is only the fluval ceramic media and the blue stuff that covers the filter cartridges I already have is that right?

you could even place the ball/rings in a net bag. then place that in the filter.. the blue filter floss you get from the LFS and cut it to size... place what you think will fit in there... dont be scared its easy and you just put what you think will fit :) on your filter ,,,, you can cut the blue stuff off your filter for now and use that :)

Ok I got my stuff to replace my filters on my marineland emporer 400 with the HOB filters. I'm kind of confused as to how to do this so bare with me. Am I going to cut out the filter pad in four squares about the size of the filter padding that is already on my filter and as for the ceramic rings I got three boxes of the 500 mg and I was going to divide that by four do you think that would be enough? And Im confused as to the filter pads which should go first. In the pictures it looks like the filter pad is the first one in and the biorings are in behind those and in some pictures it looks like the biorings are in the bottom of the filter and the padding is on top.

Ok Ive decided that the 500 g of ceremic rings is not enough to fill up both of my filters so I ve decided to go ahead and divide the 3 boxes by two and put them in one filter but did I put the filter pad in correctly?

Oooh, just goes to show I should check out the pinned things before posting questions on new topics - I'm a quick learning fry, though! This is a really helpful thread! I'm going to switch up my configuration as soon as I get my next paycheck. Time to start searching for ceramic rings! Thanks all!
