Thinking about adding a second canister or is it to much?
So I've always heard/read there is never to much filtration. But I'm now reading in some of searches (not necessarily here) that you can have to much on a planted. One forum even said that to much can take away from the nutrients which doesn't make sense to me since they are still in the water...not stopping at the filter. To much flow I could understand depending on plants and fish species.
Here's my case... I have a new in box eheim 2213 I bought on sale for no apparent reason and no additional tanks planned in the near future until I feel I have "mastered" the one I have since it is at a pretty central location in our home. I have a 40B that is I would say medium planted right now and is continuing to fill in. The fish are composed of Endlers, 12-15 CPD, 6 Corydora Habrosus, 2 rubber lip plecostomus, and 1 lone Otto, lastly a growing colony of red cherry shrimp. My plan all along was to keep smaller fish so I could have a larger stock. Well after wondering when my new Endlers would start breeding, they are now exploding exponentially hence no number given. I am trying to come up with a population control method possibly in the tank, otherwise it's just me culling.
My current filter is an eheim Ecco pro 80 which also drives a large model ista mix max for my DIY co2. Would adding the 2213 be to much or "worth" the cost to run it? My thoughts are redundancy and just added mechanical filtration. Some of the bigger female Endlers will get pissy and try to eat or just tear off small plant leaves or parts they can get a hold of. I am pretty vigilant about snagging floating plant particles but honestly some further in the column may float for a few days until I get annoyed enough to dive in.
I know the 2213 is a lot "smaller" and less powerful not sure how that would effect adding it. Would it make sense to set up one filter strictly as mechanical and the other as bio for the best efficiency? Or set up both as intended for bio and mech? With redundancy in mind having each do a different task doesn't seem to be the best way to go but I am open to some education. I've also read about people not using the 2213 basket to gain a little media volume.
Thanks for reading, I know this was long.
