Am I absolutely off my rocker?

  • We are currently upgrading MFK. thanks! -neo
I find that a single fx6 on a 75 doesn't make that much flow, I'm considering putting a second one on my 75 that has one already.
 
Dont know if i should stock the fx6 up to full trays or biological media or not, currently im running it with what it comes with which isnt alot... lol
If your tests result in non- detects for ammonia and nitrite, then the amount of bio-media you now have is sufficient.
If your plan is to add half dozen more fish, then you might want to reevaluate the amount.
Or if your fish are young, and you expect them to double or triple in size with time, then more media in the filter now, ready to expand your bacteriological population is definitely a thought worth considering.

I run an FX6 and AC 70 on my 75G, and I don't find it to be too much flow. It gives me really nice surface agitation though. I use the AC70 mainly for fine mechanical filtration. Besides the stock sponge, the rest of the AC compartment is filled with filter floss that I can easily change out as needed.
 
Why not save some money and buy a powerhead?
Thing is that I had a fx6 hidden away in a closet that I found recently, I don't remember when I got it but I have it and I might as well put it on a tank if only to establish it for another tank.
 
I dont know guys. Some of this seems unnecessary. I like overfiltering as much as the next person but you have to balance mechanical and bio with your actual bio load. And most of your bio is going to be living inside your tank no matter what filtration you have. Your only going to have as much beneficial bacteria as your tank provides enough food for. I'm running two 75 gallon sponge filters on my 75, that's it lol. Yes mechanical could be a bit better but I rely on water changes for that. Two fx6's (even fx4's) seems like an insane waste of money and electricity on a tank of this size. At some point your running so much bio media that most of it isn't even doing anything. I agree with the previous post, if you want more flow buy a power head! LRB aquatics runs a business and something like 300 plus tanks with no filters or flow of any kind, so even though that's not for everyone, it can be done. It's all about balance of bio and mechanical IMO. I'd rather have another entire setup, versus that second filter on the same tank.
 
Not to mention if your going to spend that much money on filtration, you could easily create a sump that's more effective and more functional for a fraction of the cost.

Not everyone is able to have a sump or is confident enough to have one or it just won't work with their plans. I know I'm not able to nor ready to get a sump.
 
I'm not saying you have to go that route. As I said I'm running sponges, so I'm about as low tech as it gets. It's just at some point your going so overkill it's a simple waste of money and energy. We have to keep in mind that all these fish live in nature, and nature always balances itself out. A happy medium of bio and mechanical is enough. I've learning that your water changes are sometimes far more important than overfiltering.
