AquaClear 70, Charcoal pack floating?

Hi I just am setting up my 55 gallon tank to cycle it and I have the filters running. They are aquaclear 70... the sponge is on the bottom then the charcoal then the other rocks on top...I have the same filter but the size 20 version on my 10 gallon tank but everything jams in there tighter and nothing floats.

I think it might be the power of the water pushing them up off the sponge... It is causing some of the water to overflow and come out the side where the water intake tube is..but it all still goes into the tank. Is this a problem or should I figure out a way to keep the packs stuck down?

Thanks.

Hell mkat...

The sponge is completely covering the bottom of the plastic media tray. So, you're right, there's no place for the water coming into the filter to go. Unplug the filter and remove the sponge, take a pair of scissors and cut off some of it. Place it in the middle of the u-shaped tray and put everything back into the filter. Plug it back in and adjust the flow lever to the middle position. This should help the water flow more smoothly.

At some point, you may want to remove the chemical (carbon) part of the filter media, it's not necessary. Replace it with some poly fiber cut to fit media from Acurel. The ammonia padding is the best for keeping the water cleaner and clearer.

Once the tank is cycled, get into the habit of changing half the tank water weekly, to maintain pure water conditions for the tank inhabitants.

How often are you rinsing the sponge? I have an AC50 and when I don't attend to the media for a while, I will see the "uprising". Usually the sponge is packed with detritus by this point. A simple rinse in the tank water removed from a WC and it's good to go.
The same thing happens when I put floss in the filter chamber. If it gets clogged, the water comes out from the intake side.

Fresh2o: It is brand new and clean.

BBradbury: So what you are suggesting is shortening the width of the sponge? In a way so that when it is in the U it is not touching the two upright sections of the U? If that is what I am understanding, How much should I cut? Something like 1/4" to leave 1/8" on either side?

Also if I remove the carbon part and put some of that fiber in its place do I still leave the cylinder shaped "bio-max" insert on top of it?

Thanks.

Do not eliminate the bio media. My ac 70's have the sponge then the bio media that came with it then I add another 110 bio media on top of that. The charcoal I just leave in the bag in the box. Also do not cut the sponge either its not in right or something else is wrong. The only time it will lift the media is if the sponge is clogged as stated above.

mikem691:

So to be clear your suggestion is to take the charcoal out, put the bio media rocks where it was and then buy the rocks for the size 110 and put it on top of all of that?

The only other way I could put the sponge in is to rotate it but then it wouldnt cover the base of the U in the front and back fully and would stick up higher than those little triangle marks that show where it should end...it was a tight fit to jam it down the first time and i kind of had to shove my finger in the edges and pull the sponge to unspring it and get it to contact the walls of the filter properly.

Thanks.

With the media holder out of the filter place the sponge all the way at the bottom. You want the entire bottom covered by the sponge or you will have a huge bypass of unfiltered water. Next close the sides against the sponge and insert into filter. You may have to wiggle the holder side to side as you push it down. Then add as much bio media as possible just to the point that it will always be covered by water.
When cleaning the filter just squeeze the sponge in a bucket of old tank water and swish the bio media in the same tank water. Never clean the media in tap water. The carbon you can save and use if needed to clear meds after treatment other than that I never use carbon.
Hope this helps some.

Hello again m...

Cut an inch or so off the sponge with scissors. You want there to be a little gap on either side of the filter media to allow the tank water to flow evenly through the media. If you plug the bottom of the u-shaped basket, the pressure of the water coming into the filter will push everything to the top.

All you need is a few pieces of the poly fiber cut a bit smaller than the U-shaped plastic basket and the bio-max filter bag on top.

Remember this, the filter equipment is mainly to move the water's surface to mix oxygen into the tank water and allow carbon dioxide to escape (gas exchange). You'll still need to remove and replace the tank water weekly, to remove dissolved fish wastes and to maintain healthy minerals in the water.

Constant filtration removes important nutrients from the water, so they must be replaced through a large, weekly water change. Changing out half the water weekly isn't too much.

The more water you change and the more often you do it, the healthier the tank inhabitants.

I don't understand how there can be even flow through the media with the gapping you have suggested in the sponges.
Are you saying the bio filtration is negligible or unnecessary in the filter? Sounds like it. I should remove the ceramic media in all of my filters. However, I wonder at the end of the week why I can detect nitrates and not ammonia. Is there some type of magic occurring?
What nutrients are being removed through constant filtration? This is important. I do not want to harm the fish and plants using constant filtration.

Go to time out b, telling people to cut the sponge in an ac is blasphemous. Do you understand how they work? That would allow all the water to bypass the sponge, it would make the floating carbon worse.. man...taking deep breathes over here..
Op- happy new year, now please disregard the cutting nonsense, if you've already im sorry.. the sponge is your coarse filtration, it will take all the large particles out of the water, wait a week and ring it out in a bucket of tank water, you'll see what I mean. The carbon is really only useful for removing meds and bad smells. I leave mine in the bag for those occasions. I set my ac ' s up like so (5 of them) sponge, cut to fit poly fiber pad, rocks or biomedia. The pads can be found at your pet store or lfs. Buying an extra bag of bio max to hold it all in place won't hurt ether, more space for the good bacteria to grow and clean your water.
