First off, appreciate all the comments!

Quote:
I clean the Mechanical filter maybe 2Xs a month during a W/C, the Bio filter every 3mos.
That seems like a reasonable cleaning schedule to me, I did not experience this after running this filter for a year in my planted tank.

Media came with unit - Don't understand how this is a problem???
Mechanical filter replacements are $25, that is more expensive than a 4 dollar piece of sponge that Eheim uses. That is the only piece on any filter that you really need to replace. The issue here is the combination of the clogging/flow performance and the price of the media. I ended having to alternate between two mechanical cartridges so one would dry out so I could clean it more effectively.

Quote:
I don't understand how more media is a problem???
The Eheim has more media, it was listed as a con because it has less media capacity than a filter half the cost. Sorry for the confusion.

It has to be pretty darn clogged-up to do this and is the filter clogged the filters fault or the Hobbyiest fault
I was cleaning every other day, so the clogging was not from neglect by any means. I agree that if a filter left for months and months, one would not have any room to complain. I think we can all agree on this forum that cleaning every other day is kind of absurd.

If issue is strictly related to the mechanical filtration performance of the filter. Biologically it is stellar, that said, if flow drops so does the effectiveness of your biological filtration.

Cleaning the mech. filter every 2 days is the issue with the G6, and as of now this was only the case on my planted tank. The tank it is on now is the FOWLR and it is running beautifully.

+1 for this.

What are you doing with your tank that's causing so much need for cleaning?

Is it small leaves from stem plants? Are you making a mess with MTS(dirt) as you plant/replant??

Not sure, I think part of my problem is I had high level of lighting and no CO2. There is some beard algae on a lot of my older anubias leaves.

Other than that water clarity was just low.

I dont have an excessive amount of fish for a 75G by any means.
7x loaches
2x cardinals
2x corys
3x angels
2x gouramis

No matter how little I fed the fish the filter still clogged.

FYI Just did chemical analysis after Eheim filters installed.

6.8 pH
0 ppm Amonia
0 ppm Nitrite
0 ppm Nitrate

I am adding Pressurized CO2 next week.

Another potential issue could have been the 12 hr photosynthesis period.
I dropped that back to 8hr.

Any thoughts/ideas would be greatly appreciated.

Thanks,
Ron

I do agree that the pre-filter cartridge is expensive. I found one at a LFS for $18 I bought it as a back-up. I've not had any trouble cleaning it with the brush they include. Now with the back-up I can not only clean it with the brush, I can bleach it and swap in the the back-up cartridge.

In everything equipment related in our hobby it's always a Co$t vs. Connivence question that, and to lessor extent appearance.

BTW - What's really ridiculous is the cost of that pretty grey hose
So, cut it right the 1st time.

Bingo, said perfectly!

One could argue that I jumped the gun on swapping to a new filter setup.
I couldn't be happier now with the setup. The Fluval G series was designed/marketed as a easy maintainable filter. While I agree with that it does beg the question, if something is easy to maintain, should it clog frequently.

Obviously there is a certain level of implementation/operational degree of freedom with regards to cleaning frequency.

I am merely offering my thoughts on the filter. Hopefully someone will find this discussion useful to say the least.

Ha! Yes so true, that said in Fluval's defense, Eheim hose isn't any better.
It is fantastic Tygon hosing that is far better than any Vinyl hose that you would get at HomeDepot or Lowes.

Tygon Tubing

My 1st thought would be maybe the loaches are trashing your substrate?

I had 3 zipper loaches. Once they matured what I believe was the female (gravid looking) started digging "nests" under the driftwood deep into the MTS. Totally trashed my tank to the point of a tear down and relocation of the offending loaches.

Even the regular pre-filter is pretty fine. So I could understand some events like up rooting plants could be an issue. But, yes every other day is too much.

The loaches could very well be the culprit :-)

I also think that combined with not having CO2 is causing the plants not to have the uptake rates high enough. Maybe I am smoking something there but just a hypothesis.

I have never done a high tech planted tank before. My last planted tank before this was a 20G low light and a Fluval 305, had no issues with that filter.

Since the tank isn't in balance (no CO2) and you've got fish that love to stir things up, it makes sense that your filter would clog.

I'm an Eheim person but still can't see that it's the filter's fault.

At least things are beginning to be in check with your Eheim and you're adding CO2. Things will definitely improve.

Agreed, it is not 100% the filters fault. Looking forward for the improvement. CO2 should be online by next wednesday.

Now that SomeWhatShocked and I have talked you down off the ledge, maybe the thread should be call, "Fluval G6 & Me" or "Fluval G6 my Observations" or even
"Fluval G6's most excellent adventure"

Thanks again for all the help. I posted pictures of my substrate and plants. I am sure you can imagine what my filter looks like.

Any suggestions outside CO2 (I already have that on its way) would be greatly appreciated.

LOL - How about Fluval G6 Escapades?

Fluval G6 moved to my FOWLR Cichlid Tank
2x Eheim 2217 Canisters installed on my 75G Planted.

I would appreciate some comments regarding my algae situation, posted pics in a new thread here: http://www.plantedtank.net/forums/sh...d.php?t=197535

Thanks!
