Hagen Filtration

Hey Guys....

Okay. We're not on the same page. here. I can see that. The Hagen filter doesn't need the sponge, you have the Acruel cut to fit padding to take its place. The padding is there for the bacteria colony just as it is with the sponge. You can keep the sponge if you like, just cut away a bit of it, so the water that's drawn into the filter can move more smoothing through and out the filter. If you completely block the plastic tray, the tray will be pushed to the top and the lid can come off the top of the filter. This can cause a water overflow problem and a real mess. Been there, done that.

The bio-bag stays on top of the poly fiber media to also house the good bacteria. I've used these filters for more than 10 years and the cut to fit poly fiber works much better, because it doesn't get as clogged with organic material as the sponge.

If you have a better solution, then by all means use it. This is what works in my tanks. The poly fiber filter material and the large, weekly water changes.

Ok, so the ac 20,30,50,70 i run, all with stock sponges, un-modified, a poly fiber pad on top and bio media on top of that.. all those filters running flawlessly for months,.some over a year.. I'm just lucky?? The plastic trays should pushed up and out by now? I clean them once a week, maybe that has something to do with it. The water enters through one side, if you cut said side than the water will by pass up by the sponge. The sponge is an excellent form of coarse filtraion, works splendidly, why would you want to limit it's effectiveness?

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.
Op re read this and what brookster said. B go some where else. And no don't eliminate any bio rings. Add more if anything.

Bb the mechanical filtration is the course sponge. Most all the bacteria is on the bio rings. If you cut or remove the sponge all particles will bypass the sponge and cause the bio rings to get all gunked up causing less contact with the biological filtration. Make sense?

I've used HOB's in the past and have never encountered what you're referring to. As well, I've never modified other than not using carbon and replacing the empty space with more biomedia.

Well it looks like a started a discussion...

I took out the sponge from both filters, checked the fit it seems all good and I put them back. For now I put the charcoal pack back and the bio media rocks on top... Overnight they seemed to have stopped floating and are mostly contacting the sponge... maybe there was air trapped in the fine mesh of the charcoal pack? Anyways the general consensus seems that if the sponge fits don't modify it, the charcoal isn't needed but the bio media is...

So we have PetSmart or PetLand here... I looked online... So in place of the charcoal would this product be the right one? Pisces Pro (formerly HBH) CUT TO FIT POLYFIBER PAD

From my understanding it's basically a thin pad???

So now that I am trying to "seed" this tank apparently I put the old sponge from my aquaclear 20 in one of my filters? Is just sitting on top of the big sponge that is in the 70 with the bag of biomedia rocks holding it down the right thing to do?

Thanks.

Thank You everyone for all of your time and help. It has gotten a little confusing though. This morning I woke up and the charcoal pack was no longer floating, possibly the fine mesh bag it came in was trapping air that took time to come out?

Anyways to summarize it seems like the general consensus is saying to do this...

1) Leave the sponge as it is as long as it is all the way to the bottom of the U shape bracket and all the way in.

2) (Unless of removing medicine), Replace the charcoal with either more

A) Bio Media(This? http://petca.imageg.net/PETNA_36/pim...9_main_enh.jpg )

OR

B) Filter pad (This http://www.petland.ca/media/catalog/...er-300x300.jpg ) with Bio Media on top

3) Everything is good as long as; Everything is all the way down and touching each other and nothing is floating inside the filter and it's all always covered with water inside the filter???

4) When I do a 25% - 50% water change weekly, I take apart everything from the filter, swirl it around in a bucket of water I have removed from the tank, then put it all back together???

Does all of the above sound like I am understanding right??? And if so I have taken the old sponge from my AquaClear 20, put it on top of the sponge of one of these AquaClear 70 filters and then put the bag of biomedia on top of that to help "seed" my new aquarium... Is that the proper place to put that sponge even though now that is all that is in that filter? Or should i cut out the section in the 70 size sponge that is the same size as the 20 size sponge and put it in there (so that it takes up the same amount of space but the sponge is peiced into the bigger one)? Or just leave it like I have it but add more bio media on and around it to fill up the space in that U bracket in the filter?

Thanks for all of your help, sorry for the long questions but I'm just trying to get this right as best as I can without making a big mistake in the cycling.

Sounds like you got it down. Remember if you use the poly fill its for polishing the water and will clog way sooner than the sponge. Also when I used poly fill I just threw it away weekly and replaced it. How often you will need to clean the filter will depend on what's in the tank. Plant debris or plecos make a huge mess and will plug the filter faster than guppies and fake plants for example.

Bypass

AquaClears are well known for all their bypass problems:

AquaClear Bypass Issues

I have an AC50 that I use duct tape on the side holes & top to get water to flow through all the media. I delete the carbon and use floss. Doing this means it runs at 75% if caoacity but 100% of water gets filtered.

OP - Recommendation if you can: Not sure where you got your new AC70 ..... but if you can take it back .... just tell them it doesn't work and get a Fluval C4.

No bypass issues and much more efficient filtration for about the same price. I have three Fluval C's all of which are flawless and far better filtration & efficiency than AquaClears.
