It does look a little weak on the other end. My experience is the more flow the less algae is likely to appear. Try a custom spraybar the length of the tank and it should greatly reduce the "no flow zone". Or, you could simply add a Zoomed 501 on the other end and it will help with flow and filtration too!

There are dozens of people here on the forum documenting their usage of the fixture. Just use the search feature or check out some of the tank journals. You may also refer to the Finnex sponsor forum to determine PAR data for each fixture - that'll allow you to determine how high a particular fixture needs to be suspended above a tank for your specific light needs.
If you're using a 36" fixture? 135 PAR at 6 inches above the substrate, 73 at 12 inches, 47 at 18 inches. That means you'll need to probably raise it a foot and a half above the tank for low light. Anything else and you'll need CO2 and daily fert dosing.
