true actinic

It is almost time for me to replace the bulbs in my Coralife Aqualight Pro fixture. In the past I have always used Coralife bulbs as that is what the fixture originally came with. I am now wondering if it would cause any harm to my reef inhabitants if I went with a different bulb manufacturer...

can someone explain to me what actinic light does or does it do anything other than light up the tank. How do i get the neon colors in my tank pop are there different moon lights that do that or are there different actinic lights that do that??? I know this may seem dumb but i really do not...

Hello everyone, I currently have a sunpod 2x250 mh fixture with the stock double ended 14000k bulbs, I believe they are sunpod bulbs. I want to go to a 10000k bulb and want to know if anyone has any suggestions on what brand bulb I should go with? the 14k's are a little too blue for my taste...

I am going to sell my 5 gallon all in one. I bought it about a year ago from Cadlights.com. For some reason they don't offer these anymore, I don't know why though. *T5 lighting (10,000k daylight, 03 true actinic blue) 4 bulbs (24w). *Extra thick, seamless bow front glass panels. *polished...

Without overly stressing my tank, what's a good schedule of water changes to help bring nitrate's down? It's a 55 gallon tank, no refuge or sump. Has some zoas, a frogspawn, mushrooms, another coral I can't think of what it's called(looks like green star like grass) and my xenia, as well as the...

OK, after the algae explosion, I stopped dosing like I was told I needed to, and got a calcium tester. . and it seems if I used the darn thing right, that I have lots of calcium(it took forever to turn the water blue). The water is out of limestone well, so that might be why.. . Anyway, I...

I currently own a 90 gallon Lps with hopes of SPS coral tank. I am using an odyssea 2x 250wMH bulbs and 4x65 watt. I have had my tank running for a year and half. The rock is 3-4 year cured. I inherited the rock from my lfs friend.(rock from awesome display tank) n e way. I have used the odyssea...

Ok, the time has come and I can't hold on to these tanks I love any longer if I'm going to get moved to Canada. I'm going to start with selling the LR, then the fish and critters ('cause I can't catch them with the rock in the way and I don't have a large container to move anything into)...

I am wondering if it's possible to have too much air moving across my MH fixtures as to prevent them from getting up to temperature and/or PAR value. I'm running ROIII's with Reeflux DE 10k's on IceCap 250 eballasts. Recently I've been noticing some STN on some of my SPS and one of my oldest...

Well, I think I found the culprit for the poor hammer coral, the tank got up to 86, and since I turned it down, he seems to be recovering a bit. My worry is what to do in the summer. There is no central A/C in this house, and no way to put it in(and no, a room AC would not work, you'd have to...

I'm sorry, this question has probably been asked over and over but I haven't found what I need searching through past posts. The more I read, the more confused I get. So many choices and it seems like there isn't a general consensus on what works best. Before going out and spending money on...

Last night there was an explosion of this red/purple algae. It is long and stringy and is growing on the sand and rocks. Can some one tell me what it is and how do I get rid of it. I use only RO/DI water with 0 TDS. Thank-you very much. Joe 75 Gallon Tank 30 Gallon Sump Super Needle Wheeled...

so after being a member for several months and getting great ideas from everyone on this site, i have decided to upgrade to a 75 gallon tank and make it a reef tank...i picked one up from aquarium concepts about 3 weeks ago when they had their $1 over wholesale sale. And here it is: The...

My sister is sending me a new light for my fishie tank a JEBO ODYSSEA 48" BLACK QUAD Compact Flourescent Fixture, I am so tickled, get this phosphate/sand issue cleaned up, and i can try corals!!! :) sorry, silly little things please me LOL

I am trying to decide which I like better...I've always run what I think are 460nm's (labeled as Actinic 03 does not actually say what nm they are) which are more blue, right? The 420nm's are more purple/pink/violet? I just added a 420nm by accident and it seems to make my corals much more...
