hey are the hagen power glo bulbs good for plants, they have an 18000k rating but it says on the package it is great for reefs and plants...I am just worried that it may cause algae.
I am asking this because I currently have a 75 gallon planted tank and about a month ago it was covered in beard algae, at that time I had 170 watts (2 coralife 10000k bulbs and 2 20 watt power glo bulbs. No co2 (which was prob the culprit) now I have 130 watts via the coralife bulbs and I want to know If I should put the other 2 power glo's back on now that I have my 3 bottle Diy co2 system up and running well. right now the growth is lush and good, but It is just not very fast. I think the other 40 watts would speed things up, im just not sure If I would get algae again..
