reverse photoperiod

I have a slight problem with hair algae in my 2 overflows. The teeth get clogged up and I have to scrub it out with a toothbrush every other day or so, and inside the overflow gets overrun with the stuff. I realize it's acting like a mini algae turf scrubber, but if I head out of town for...

my ph is always on the low side.. and my alk is pretty good.. anyone know any methods of just increasing the ph? would a kalk drip do this without raising the alk?

... and I need some expertise. So here's the deal, for 2 reasons I want to grow frags in my sump. A) I'd like to not ugly up the display with my classy frag rack, 2) my pH is pretty low and I'd like some reverse photoperiod, and D) it'd be a nice supplement of tank funds if I can get some...

ok so with both two different test kits and a monitor my ph is always low. I checked the calibration of the monitor and its perfect. Yesterday it was at 8.00 and got to 7.75-7.80 at night. My alk is maintained between 8-11. So whats the deal? does it matter? should i even worry?

I checked my PH tonight long after the lights were off and my PH is 7.75. Will this go up once the lights are on? is this swing normal?

I've seen a couple mentions here, and on "other sites" that talk about a hang on the back fuge for a nano. Do any of you know anything about these? I'm trying to figure out how much space I need to leave between my aquapod nano, and the wall in case I want one of these down the road. *...

So, I'm wrapping up a year of having my AquaController and full-time pH monitoring. Throughout the majority of the year, my pH would swing from around 8.05-8.25, hardly every falling below 8 or above 8.3 in nominal conditions. When it did fall below 8, I knew it was time to replace my kalk in...

OK I know some of you thought it was sacrilege that I tore my 450-gallon system down. Numerous issues compiled and aided in the decision. First off was the system itself. I think anyone who builds their first dream system will tell you that a lot more thought went into building it than...

Polls are fun to vote in and fun to watch the results. HOWEVER, I'm REALLY wanting to know WHY and the RESULTS you have achieved, while using these additions to your reefs. I'm considering a set of Blue LED Moonlights. I'm wondering if these really benefit the fish/corals, or are they just...
