NickG83 Posted August 17, 2021 Share Posted August 17, 2021 Hi all, I’ve just set up a 160L (30 gallon) planted tank, depth of tank is 16inches. Substrate is fluval plant substrate (basically dirt I think) with a layer of gravel mixed with course sand capping it off. Plants include Vallisneria, crypts, pogostemon stellatus octopus and limnophila sessiliflora. I have a fluval aquasky, and I’m wondering how I should set the lights. You can obviously customise it, and has red, green, blue and white lights that can be all set separately, any ideas how high I should set it? My plan currently is to set the white, green and red lights to 50% and blue to 2% (I hear setting the blue light to high will cause algae) and then gradual increase them by 10% (1% for the blue) increments every week until I’m at 100%. Thoughts? Thanks I advance. Nick Link to comment Share on other sites More sharing options...
Mmiller2001 Posted August 17, 2021 Share Posted August 17, 2021 I would try R50% B45% and G to visual desire. If you want more red, increase it alone. If you need more brightness, raise red and blue and green in ratio. I would only use white if you are unable to achieve a brightness you desire. 1 Link to comment Share on other sites More sharing options...
Scott P. Posted August 17, 2021 Share Posted August 17, 2021 I run my Aquasky at around 5-6 on blue. Mid 50s on red, mid 60s on green and about 75 white. If I go any higher I get almost instant algae. 1 Link to comment Share on other sites More sharing options...
NickG83 Posted August 17, 2021 Author Share Posted August 17, 2021 Thanks @Mmiller2001 @Scott P. It’s the first time I’m using a proper plant light, and just a bit worried I’m going to end up growing a load of algae… Link to comment Share on other sites More sharing options...

It is fairly normal on a new tank. Looks terrible but usually goes away fairly quickly. Also as far as fertilizers go, I dose a small amount daily. I don't believe in large weekly doses. The plants can't use it all in one setting so the algae grabs it. I give mine a few drops daily during the middle of the photo period. 1 Link to comment Share on other sites More sharing options...
NickG83 Posted August 17, 2021 Author Share Posted August 17, 2021 @Scott P. Yeah, I’ve heard dosing a little fertiliser everyday is better than a large amount once a week. 1 Link to comment Share on other sites More sharing options...
