Water Circulation in a 75 Gallon


New to these forums but I've been browsing for years. I'm in the process of setting up a 75 gallon planted tank and was wondering about water circulation. I could experiment myself but why waste time when there's plenty of experience right here.

I have a Rena XP3 as well as a Koralia 2 powerhead and was curious as to what the best configuration would be for optimal water flow. My tank is currently filled with water and substrate but nothing else at the moment. I have the spraybar mounted horizontally on the left hand side panel spraying towards the right side and slightly down, and was going to place the powerhead near the back right hand side, pointed to the middle front of the tank. Is this alright or is there a better configuration?

My only other idea was to mount the spraybar vertically in the back left corner and have it angled to the front middle as the powerhead is.

One more thing of note, I'll be using an inline co2 diffuser so it will be comming out of the spray bar.

I have diy undergravel jets

here's the link to someone's instructions. http://www.cichlid-forum.com/articles/ug_jets.php

Mine is not as complicated; I only use 1 powerhead with 3 outlets. You can set it up anyway you want, with the nozzles directed towards your deadspots.

I've always sorta copied the Nature Aquarium idea, of placing my outlets at the very tops of the foreground and angle them towards towards the top-center of the aquarium.

Never had any problems with dead-spots, since the outlets dont get covered by tall growth in the back, in case I neglect a trim or two.

I had my XP3 output on the left side pointed right and placed a Koralia 2 on the front right side angled slightly down toward the left back.
