Heya, I got the eheim 2217 in the mail and opened it up. Where should i put the intake/spray bar? any specific location or does it not matter? i was thinking spray bar=middle, and intake at the left corner.
If that's the only filter you're running, I'd put them at opposite sides of the tank if possible.
Anyone here got chichlids? what did you use to decorate the tank if you didnt use plants?
That's a pretty wide open question. There are all sorts of cichlids, some of which are a bit sensitive, some of which will live in your toilet. Many African cichlids come from lakes that have very high pH and hard water, which wouldn't be suitable for many planted tanks. Other cichlids like soft water. Most are fairly hardy and adaptable. For example angelfish are cichlids. Many get too large or are too aggressive. Some are small and relatively peaceful. I have little Apistogramma in my planted tank (he's my avatar). Just look up whichever cichlid you like to see how big they get and where they come from. There are quite a few cichlids that are suitable to a planted tank.
i can have the intake with the power filter on the left side and the output for the canister filter on the right.. but that would mean that a lot of what the canister is picking up is relatively clean already.. i guess i can put the power filter in the middle, the spray bar on the right, and the input on the left..?
The HOB doesn't have the ability to change output direction, which makes placement a bit more difficult. Why not try setting up in a few different ways and see what the flow looks like. I like to watch tiny bubbles in my tank and see where they go to throughout the tank. I especially pay attention to the back corners, and the path they take from the filter outflow since that's the entry point for the CO2 enriched water. I always find the back corners of the tank to be the most difficult places to get good flow. I recently moved my intakes to the bottom of the back corners of my 65 to try and make up for this.
FWIW, I am setting up a 90 gallon with a Cascade 1200 (made for 150 gallons, around 300 gph). I plan on getting myself a bit more filter, I have a lot of stuff lying around, maybe a merlin fluidized bed that's going back I also plan on putting koralia nanos in each corner. The new ones run 250 or 450 gph and are quite a bit smaller than the regular 750+ gph models.
