Just recently discovered I'm not supposed to be running carbon in my planted tank. Perhaps now I can finally take care of my algae problems. Anyway, any recommendations on media for mechanical filtration? Is there something for another filter I could purchase that would work well with my marineland? I don't remember the model of my filter, but it takes rite size C cartridges. For now I have cut off the inner plastic part and emptied out the carbon, but it seems really unstable. I need some better options.
I was thinking about taking a few of the pads from my Rena xp3 I use in another tank, and cutting them enough to fit them into the inside of the filter, though I have a problem with the biowheel when I keep too much media in there. The water will exit from the overflow and not the bio-wheel, which will just stand still without motion of any kind.
Also, is having the bio-wheel on there alright? I've heard some say before that they discard the bio-wheel as it causes even more turbulance.
Ditto. I've also found that ScotchBrite pads (the green ones) work well as a fine mechanical filter, but they should be cleaned often as they clog easily.
Yeah...that's what I just did...I cut into the plastic and made a giant mess to get the carbon out. I just wish there was something easier, like maybe one of those cartridges where you fill the media in yourself. Perhaps that's what Dewmazz was referring to.
And is it okay to take off the biowheel? The only reason why I ask is because when I used to keep a lot of media in there once, the biowheel stopped running as all the water was exiting through the overflow part and not through the biowheel. Anyway, when I did a test on my water, my nitrites were up to .5ppm... and this tank had been set up and properly cycled for months already! I cleaned out the filter so water made it into the main part of the filter and push through the biowheel. By the next day the nitrites were back to 0.
Just curious. Perhaps it was something else that caused that. I don't know. I would just feel really daring by taking off my biowheel. Perhaps the bacteria will grow elsewhere without it? Should I give it another shot and see?
Thanks!

And yeah... Pzuzu is a reference to the demon...though I much prefer this spelling. I've used it as my nickname online for any chatroom, forum, etc. I've ever been a part of since I was a curious teenager. Just kinda stuck. Some of my friends even call me by Pzuzu. Heh... anyway...
Actually, I was just referring to the green scrubbing pads you use for washing dishes . I have a small Bio-Wheel on my 2 gallon eclipse explorer, and I'm fine with or without it.
Nitrobacter and Nitrosomonas (the good ammonia-eating-nitrate-expelling bacteria) will culture in the gravel and in the mechanical media too. The bio-wheel provides an ideal environment to culture these bacteria because they utilize a lot of oxygen, and as the wheel spins, the bacteria is constantly exposed to the air. Be sure to keep the axles free of debris with good waterflow to keep it spinning.
And a Nitrate of .5 ppm is fine. 10 - 20 is okay for plants. I like using the biowheel because it gives my plants a "choice" between ammonia, nitrite, and nitrate and it lessens the stress on my fish.
Very good point, tetrafreak. So I'll just let a carbon cartridge sit in there for two weeks, take it out, clean off the debris, put it back in. But I would still like some more mechanical filtration in there...part of me feels like that blue pad just isn't enough. I'll check out the sponge from AC400 filter.
Good discussion, espec. re charcoal. My limited experience shows that charcoal media gets every thing out of the water incl traces & ferts. Not what you want. I've a question for canister users. Is there a spray bar that can be adapted to a Marineland Magnum 350 to minimize surface agitation, or is it strictly DIY? Also has any one else used the Lee's mini-balls in a 350 as media with the foam cover as a pre-filter?

I just bought a bulk filtration sponge from Big Al's for my Penguin 100 and took out the cartridge, and cut a number of sponges the same size and shape as the cartridge and shoved it in. It's been working flawlessly for 2 months.
See...I've been using two filters in my tank. One aquaclear 50, and the marineland biowheel for a 50g tank. I have a 46g tank that has been very problematic in the algae department, and someone once told me it's because I have so much current in the water. Is this true? With the aquaclear, I just took out the carbon and put two sponges instead of one. I have it set on the low setting to keep the current down. After taking the carbon out of the filter and changing my kh buffer from corral to baking soda, now the inside of my marineland is empty except for a carbonless cartridge...and the current is horrendous. That's one strong filter! For the time being I have shut it off completely because the plants in the path of the currents are growing some serious algae. I guess it was true all along that high currents cause algae. Who knew! Well, probably most of you guys on here. So, anyway...I only have the aquaclear running now on low. Hopefully that should be okay. If it sounds iffy...please speak up.
Again, thanks all for the suggestions.

Samael: you should listen to Original Sinsuality by Tori Amos...she sings about you for a little bit in it.
After I typed up my last reply, I asked myself the same exact question. I guess that's probably just what it is...the water disturbance, and not the current. I don't know for sure though...but I guess it now makes perfect sense.
Well, I am in the middle of that process myself. I just purchased a Fluval 204 to replace my Penguin 100. I've been having trouble keeping my CO2. If this change ups my CO2 concentration, than I'll know that it's definitely the bio wheel.
Interesting discussion. It's the splashing at the surface that releases the CO2.
Basically, the splashing allows greater surface area of the water to be exposed to the atmosphere (air). This will allow the CO2 to diffuse into the air, and outgases it. The biowheel creates this aggitation and water to atmosphere exposure.
Water circulation/current in the water helps move whatever dissolved CO2 to the plants. As long as it isn't creating turbulance or surface aggitation then your CO2 won't be outgased.

That's pretty much what I thought. Once I remove that biowheel and put in the canister, my CO2 content should increase. Thanks for confirming that.
