I have a 30 gallon and 20 gallon high . I was having issues with my plants growing, so I bought a hygger full spectrum lights for each says easy programming, but I'm not finding it easy at all. I'll I've managed to do is raise alge. So just stoped the program I guess was preprogrammed with blue lite running from 6pm to 11 :30 pm which I was told by my local fish store wss causing my issues. If anyone and help with a schedule for lighting or how to schedule it would be of help. Ive tried the company but no respons.
