More filtration for my 125gal

I appreciate all the help everybody. I am going to replaced that Hydor Circulation Fan (1050gph) with a HOB filter. I have been reading on some of the HOB filters that are at my local pet stores, and have noticed the flow rates are far below the fan I have. Replacing the fan with an HOB will decrease the current within the tank, which is part of what I am looking for (due to the fish I plan on keeping), but also help the Marineland C-530 canister with filtering the water. I know the fish I will be keeping are somewhat messy, especially due to their large size when adults, their bio-load will be substantial, so why not go ahead and get an HOB to help? It can't hurt, and it will also reduce the flow/current within the tank, since the fish prefer slower currents.

Were it me,, I would add the extra filter .You'll be gald you did especially as the fish grow larger.
Were it me,,I would use large size pea gravel for substrate at no more than one inch deep to 1 and 1/2 inches deep which would make gravel vaccuming much more efficient than deeper substrate.
Although sand is cheap,, I might not choose this substrate due to digging,rooting through substrates that these larger cichlid's are prone to doing.(easy for waste to get buried if you don't stay on top of removal)
If I did choose sand however,I would slope the sand so that it is deeper at the back of the tank, and shallower at the front. Depending on filter placement, (return flow )this would cause majority of waste to accumulate at the front of the tank where it is more easily removed than in the back, or around rocks,pot's,caves,etc.
Might expieriment with the return flow from filters and hydor circulation fan you spoke of, to see if I could not aim them/ it, in such a way as to push the debri across the sand to one of the filter uptakes.(would use prefilter's over uptakes)
If using sand,,I would shut off filter's while performing maint in the tank to help prevent sand from finding it's way into impeller assembly of filter's.
Hope some of this helps.

Yeah I am using sand. I currently have egg crate at the bottom to help distribute the rocks weight in the tank. I do have the sand in a wave like motion on the floor. I shut off everything when doing maint. Good I dead to cover the uptake just in case, I will take care of that this evening. In fact, when I do maintenance, I actually take the gravel vac off of the hose, this allows me to hone in on the waster and suck it up more efficiently, while using the vac, it just sturd everything up, effecient all the waste just rested at the bottem. As far as the prefilters over uptakes, you do mean putting it over the uptake...right?

ive kept cichlids for over ten years. im by no means an expert but i can tell you they do make a wicked mess. the part about half the food coming back out of the gills is not blowing it out of proportion. imo im sure if you kept up with it real well you would not need to add on. but like mentioned earlier stuff happens life gets in the way sometimes and the fish may get neglected. this is when the extra filtration is a big help. being said i have a cascade 1000 canister and a whisper 60 hob on my tank.

i ran the whisper alone for over ten years but it gets dirty pretty quick. i got the cascade from my girlfriends tank. it leaked and she didnt want anything to do with it. since then iv been running them both together and it took way longer before the whisper went into overflow mode as i call it.

Nice! Thats what I like to hear, some who actually tried. Appreciate the input.

No, the ammonia produced won't be strictly a constant, but it should be fairly stable and never varying by more then a couple percent. Small enough that the system can easily compensate without a noticeable 'mini-cycle', as in your liquid test kit will always read 0 ppm ammonia, even if their is a trace amount.

I was more arguing against the belief some have that more filters, or bigger filters, will make the water 'cleaner' which simply isn't the case. Like putting a Fluval FX5 on a 55 gallon aquarium with regular community fish ... that massive filter isn't helping anything (even if you ignore the huge flow rate). Or putting two Aquaclear 110 filters on the same tank. Things along those lines.

I don't dispute that cichlids are large waste producers, but I do stand by my statement that having more filtration than needed for the amount of ammonia produced is pretty pointless, unless you need the flow for the fish.
maybe its not extra filtration but its another flow of water disrupting surface area of water allowing better mixing of oxygen and water.
