I would like to add...I start up 1/4tsp of sugar and 1/4 tsp of yeast with 5oz of warm water about 10 minutes before I mix the bottle. When I am done making the bottle, I pour this "starter" as the last thing in the bottle...
I've got to wonder if you really need it though? My 29 had 40 watts on it and some sunshine and I couldn't grow much. What did survive I could see was lacking light rather than anything else. The fish were able to supply the other nutrients at that pace easily.
And it will reduce brown algae (maybe even keep it from coming with such low light)...did this for a friend with a 20g high and only 35 watts of light...no brown algae anymore and all she has is DIY running into a HOB filter.
So what is the correct lighting or watts for a 20 gallon high? I have a limited budget so i have just bought the glass top & the perfecto 2 bulb hood & put my old hood with a single bulb so that makes it 3 15watts. Any suggestion is gladly appreciated.
Since you've spent money on the additional fixture already, the only wise thing to do is to overdrive 2 of the bulbs in series (If you want to increase the light). That's what I did on mine. Read the ODNO article at the articles link. If you only have low-medium light plants, your current set up may work just fine.
From what I have seen all commercial strip lights have magnetic ballasts. With 45 watts over a 20 gallon tank you have a low light tank. Remember that strip lights have very poor reflectors most of the time. When funds become available you might want to look at an AH Supply 55 watt kit for one of the strip lights.
