Paul2426 Posted January 10, 2023 Share Posted January 10, 2023 (edited) I have a 45 gallon tank with a couple of wisteria, jungle Val, and Anubis so far. No CO2. Any suggestion on how to set the Fluval 3.0 light so that the plants get sufficient light in a deep tank, but not enough to cause algae bloom?

TheSwissAquarist Posted January 10, 2023 Share Posted January 10, 2023 I’ve found that light settings are really problematic because tanks are so variable: My suggestion is that you try a hit-or-miss strategy where you just put/keep it on relatively normal levels unless there’s large plant dieback or an algae bloom. Keep us updated on how it goes! 1 Link to comment Share on other sites More sharing options...
JoeQ Posted January 10, 2023 Share Posted January 10, 2023 (edited) This question will probably be better answered in the 3.0 thread. as per my settings, I use the Bentley Day sim. In my signature there is a link to download a spreadsheet that helps you reduce the output by percentages. Edit; I'm 21" from substrate and use 35~38 percent power. I started at 33 percent when my aquarium was lightly planted Edited January 10, 2023 by JoeQ Added edit info Link to comment Share on other sites More sharing options...
MattyM Posted January 10, 2023 Share Posted January 10, 2023 I keep my blues really low, like under 5%, and go for a longer time frame with lower intensity vs shorter with brighter intensity. I also just prefer that look, and the fish seem to come out more. Once I switched to that approach my staghorn woes pretty much went away 🤞 Link to comment Share on other sites More sharing options...

Definitely a question for the 3.0 thread, but just a quick offhand to get you started, I almost always start with: Pure White: 45% Warm White: 40% Cool White: 30% Red: 35-40% Blue: 1-5% Give the plants a week at least to get used to the tank and the water, then focus a bit more on how they are doing.
