Thanks Tom,

When I first took up this hobby I thought lighting was rather a simple subject. It wasn't until I started reading through your site that I started to learn more. Maybe I should have paid more attention all those years ago in school

When I had the 150W over my corner tank it drove really high growth rate from the plants, as well as some algae. This is why I've now reduced it to a pair of 24w T5s.

Did you find that 3 x 150W over your 135G gave very fast growth? I found that the demands on me of a fast growth tank was too high. What little time I had off work was spent up to my armpits in fish tank! I think I might go with a bank of 70W. You said one every two foot?

The tank is now taking shape. Once I get the filter bags and alter the sump as per your recommendations I should have the CO2 stable. Just the lighting and then it'll be time to plant!
