Sorry, I meant as far as growth

Did the bluer light have an effect on your coral?

I'm actually hoping to purchase the new bulbs tonight, and just wanted to ask a couple more questions before I set down the money. Since 15,000K is more blue than 10,000K what atinic spectrum should I go with, or should I go with a 50/50? Basically what combinations are suggested? What brand and...

Since you are using them, I am guessing that XM are a good brand to go with for halides. What brand is good for the CF's and what wavelength atinic420, 460 or 420/460 combo?

I could be mistaken, but I believe the angle you are looking for is 135. 180-45=135

I had been using Coralife bulbs since that was who made the fixture and I thought it would be best to keep with the same, but with the lack of growth, I am begining to question my reasoning.

I have a Aqualight Pro HQI/Compact Fluorescent Fixture installed about 12 inches above my 72G bowfront tank and I do have glass covers on the tank to help lessen evaporation. Currently it has 2 150W @10,000K metal halide bulbs and 2 96W at 420nm Atinic compact fluorescent bulbs installed. Since...

I like to look at ammonia just to be safe. You can also look at Ca levels.

Well, I did a 20g water change last night and here is what I did in an attempt to slow/stop the spreadof the algae. Throughly cleaned the gravel, and meved around some of the LR to get into areas I perviously hadn't gotten to. Sucked out a great deal of brown/green stuff by doing this. Added a...

Originally Posted by Yosemite Sam Something like rowaphos or phosban may help. Like I said, just because you get a 0 on your phosphate test doesn't mean you don't have phosphates, the algae may be using it all. You have a good amount of live rock, just take the bioballs out. Do you think...

Originally Posted by Yosemite Sam There are a few maintanance things you can do to help. Ditch the bioballs and the fluval, they're not doing much for you. Unless you clean the fluval regularly, it's going to be trapping a lot of gunk. Your phosphates may test at 0, but that's because the...

Hi everyone, I've had this tank up and running forquite some time, but lack a variety of coral due to lack of funding. However, I recently started getting some algae growth with is threatining to kill the coral I have. I checked my water levels and are all good.....including phosphates. I...
