nub question. I have a 10 gallon nano right now (all softies, snail, shrimps, anemone) that I'm planning to move to a 30 gallon long with 35 gallon sump and skimmer then add some fish. Can I simply move the rocks and corals to the 30 gallon, and add 20 gallons of water to the mix and slowly...

Its in the darkest area of the tank with good flow. In the dark I can see a small hermit crab on it. I think the coral is dead.

And as far as tissue recesssion, I don't see any tissues on it. If you are talking about the base, the base is still the same.

ok that's a relief to know. the stony part is still orangy color. I have put it in a countainer and put frozen food into each mouth and leave it there for 30-60 minutes but they don't eat it at all. I haven't tried the light at night trick. I will try it one hour after turning all lights off. I...

I bought this coral two weeks ago. I haven't seen it come out. I have tried to feed it but I haven't seen it eat at all. Is it dead? How long does it take before they come out?

I moved one frag of my zoas and noticed that it's got green algae on the polyps. How do I get them off?

Man, prices on these LEDs are dropping. I saw some blue and white 120s with dimmer for $120.

Hey Chris yeah we don't know what happened to his tank. I think the MH and LED flood lights is a great combo like raheel is doing. I like your idea of RGBs. If you have them all on, then you get the full spectrum white right. Add a second blue only flood and I think you have the basic...

Dude! you're my GTA??? frick! LOL awesome! Hey join the GTA aquaria group. lots of guys there. they actually have a BBQ today but I can't go. its mother's day weekend and gotta spend time with family.

By the way I'm using water dip to get rid of fungus too. I made the mistake of reading some threads saying you don't need to acclimatize soft corals. duhhh... WRONG! that's how I got fungus on my new frags of zoas. 5 days later, a lot of them had fungus... fresh water dip got the fungus off...

This is a good page on stuff in your aquaria. I think it's a bristleworm. How to Identify Worms in Your Reef Aquarium

Apparently, this happens when zoas get fungus, and nothing new. FYI only.

I just wonder if my zoas got foot fungus coz.... I noticed some of the new frags I bought started developing fuzzy stuff on them 5 days after being brought into my tank. I did fresh water dip, and the white stuff washed off. But this one frag, OMG, it smells PUTRID. I have kept it in a salt...

Woa, check out this flood light. This will grow corals. 144 watts! I like the ratio of blues to whites too. 32-16. Looks like it's got nice lens too. at $129 including shipping this can't be beat! Trying to find something smaller for my nano. Star 48X3W LED Aquarium Light Lamp for Coral Reef...

At times, ignore is most useful when discussions become fruitless. My thoughts, research findings, and opinions are here. Use it if you find it useful. Ignore if you don't. And thanks for your inputs.

You have taken me out of context, and you would have seen that it was in DIRECT RESPONSE to the specific lights Raheel was talking about, the popular nomenclature for violets: To which I responded as this immediagely: So, it was pretty clear! I was responding to THIS "UV LEDs" that Raheel...

Mr X, I think you've done a wonderful job giving thousands of advice to people on this forum on LED lights and lighting in general although I do not know the source of your knowledge. Now I keep saying LOOK AT THE SPECTRUM of your blue lights. The articles I indicated and in countless...

you can get the growth with just blue. I never said nor did these articles say you can't. It may not be the best growth, depending on the specific type of corals. the articles are specific on what corals does best with what. I have coloration on my corals. It is that they are not as good as the...

early part of the article articulates the reasons why 400-500 is important to most corals. Note that royal blue and blue LEDs are in the 450nm range, so will NOT cover the 400-425/435nm range. Thus the need for violets. now the LEDs they measured were properties for the SPECIFIC LEDS they...

Oh, here's a really good well-researched paper on light spectrums that corals absorb. It gives pretty good explanation as to what spectrums corals absorb and why. The good news here is that since 2012, better violet (400-450nm) LEDs are out, as per the article. It discusses violet and blue...

I think if you got MH then most of your spectrum needs are covered including UV because MH IS full spectrum. And LEDs do not come close to the intensity that MH achieves, according to a recent EPA study. That combo should be fine. I'm leaning towards MH if I got a lot of headroom. If not, then...

hey Oyf, you might want to read an article on light response and SPS corals. Some species responded well to the red spectrum. This is one reason I am thinking of going to MH lighting. It's full spectrum.

It's my personal experience. I bought frags from local guys who have those colors. my tank's LEDs don't have them (My LEDs got blue, royal blue, 6k white, and reds), and I am not getting the same colors on my zoas that were there in their tanks. They had cyan yellow and even pink LEDs as well to...

Sweet. Should be much easier on the electric bill vs MH.

So I had the mushroom in a corner.. today I found one piece, looking like a completely whole mushroom, in the front of my tank, nicely open. and the other ones are all in a long stringy mess, twisting on itself, after splitting into, from what I can see, two more pieces. It's rather late now so...
