Lotsa Green Film Algae. From New Lights?

By adding more intense lighting you just threw your tank balance off. The result is increased algae growth. Give it time and it should stabilize again.

Awesome. Thanks, Ryan.

Funny thing is .. the 250w HQI doesn't really seem all that much brighter comapred to 150w HQI. I mean, there is a noiticable difference but I for sure would have thought it would have been a lot brighter.

Quick DE bulb question. When you place the bulb in your pendant, there is that little metal part inside. Does this metal part face up towards the reflector or facing downwards , facing the water surface. I am just curious if it makes a difference in intensity or anything? Would anyone know anything about this?? I'm a bulb newbie.

There is only one way to put the bulbs into the socket. At least from the bulbs I have seen..

lol then I guess that answers my question... I could have sworn there was two ways. Was I clear in my post? If not I'll try to get a pic and show you what I am talking about .

It only lets you put it in one way as it has ceramic on the top of the ends.
*Note this is a side view. The top faces towards the Upper Left corner of the pic.



On a side note: With DE bulbs never ever touch the glass with your fingers!!

Yeah I think I am confusing myself now. I can't even describe what I am talking about really. Inside the bulb is like a metal strip, and when the way the bulb is in my pendant, the metal strip is facing down towards the water surface, I thought it should be facing up towards the reflector so it reflects better? I am probably way out to lunch here.

Did a google search for Hamilton DE bulbs but can't confirm this is what yours looks like. Maybe you can though.
