My 125 gallon African cichlid tank has been running for about a month now, and I'm beginning to see where my filtration/water flow issues are. My current setup:
125 gallon All Glass tank with predrilled 'megaflows'.
Oceanclear sump model 2 wet/dry filter with 950 gph
XP3 canister filter.
UGJ's with 700 gph
pump (6 jets).
The right side of the tank has low 'crap collection points' (where fish waste accumulates in the substrate). The left side, however, has high 'crap collection points'.
I've made a diagram of my current filtration/flow setup (not to scale, of course):
As you can see (hopefully, if my diagram is at all readable), the XP3 intake is on the right side of the tank, where the low 'crap' point is. So, I'm trying to figure out how to modify/enhance my filtration/water flow to get low crap collection on the left side. My first thought was to get another XP3 and put the intake on the left side, as in this diagram:
Another option that came to mind was to have an additional intake not only on the left side of the tank, but in the middle also. I don't want to get 2 more filters, however. So, I came up with this idea. I already have a 950 gph
pump sitting around waiting for a use. I could get an Oceanclear 340 filter, and hook the pump up to that. For intakes, I could put two intakes in the tank, one on the left and one on the middle, and then connect them outside of the tank, and have the combined line go to the pump:
I don't really want to change my UGJ system, too much work.
Given the fact that the right side isn't bad and that's where the current lone XP3 intake is, I think the UGJ system is OK. So, two options I'm considering:
A) Adding another XP3 with intake on the left side
B) Using my unused 950 GPH
pump with an OceanClear 340 filter, probably with two intakes, one on the left, and one on the center. One issue with this option I'm not sure about is would this be TOO much flow for Africans in a 125 gallon tank? (950 gph
wet/dry, 350 gph
XP3, 700 gph
UGJ's, and now another 950 gph
with the Oceanclear?)
Any opinions would be greatly appreciated!
