Has anyone run into this before? I have been using the Red Sea Reef Foundation test kit for many months now. I'm about to run out of reagents so I bought a new kit. I then tested my water using the two different kits to see if they provide similar readings (they should, right?) My tank...

More spawning action in my reef tank. Perhaps the cooling weather has convinced my inverts to start getting in the mood :) You can only see the baby shrimps that are reflecting the flashlight, but they were everywhere. I wonder how my fish will react when they wake up in the morning.

While doing my random nighttime flashlight inspection of the tank, I saw one of the emerald mithrax crabs releasing larvae into the water. At first it was releasing several dozen babies each time it flapped the plate on its underside. By the time I got back with my camera, it was almost done and...

I have this favia for almost 9 months now and I have been experimenting with different locations in the tank for optimal lighting for this coral. My lighting consists of three 120W dimmable LEDs. Blues are set to 40-45% and whites are at 10-15% (Analog dials so there may be some variances)...

First, a little history: For a few months I was manually dosing the BRS 2-part solution and the parameters were doing fine during that time. Ca: 440-450ppm. Mg: 1440-1450ppm Alk: 7.0dkh. The Alk was a little lower than what I would like (I would prefer 8.0) but since I got the manual dosing...

When you use the titration kits for Ca, and Mg, do you record the readings as soon as the color changes? Or do you wait a few seconds to see if that color holds? This is what I have been experiencing lately with my test kit. For example, the Ca test: 1.When I start adding the titrant, the color...

Reading up on lighting in general (not just reefkeeping specific), there is information that the color temperature ratings (in Kelvin) for light sources are based on their maximum illumination. When those lights are dimmed by limiting the power source, then the color temperature changes in...

Try telling that to this CBS... Actually this is just a CBS molt that landed on the zoas. I'm sure the zoas are yelling at the CBS right now. "Dude, your laundry... PLEASE!"

At first I thought this was a branching alveopora. But I was told recently that this might actually be a gonipiopora (sub-massive growth form) because each polyp has more than 12 tentacles. It is difficult to get an exact count, but from my pictures I could count between 18-20 tentacles per...

I decided to experiment with fragging this fuzzy blue mushroom (could be a St. Thomas). It has just been growing bigger but not splitting or producing any little ones so I wanted to help it along. Once I pulled out the small rock that it was attached to, I saw one fully formed baby fuzzy blue...

I have been thinking of adding more fish to my tank, and I am leaning towards a small group of chalk bass (maybe 4). Does anyone have any experience with them? Any issues that I need to be aware of? Current livestock (100 gallon mixed reef) 1 hippo tang 1 amphiprion clown 1 scissortail goby 1...

I have a bunch of different clove polyps in my tank. Some are medium sized that have neon green patterns which like really like, but they grow really slow. And then I have a bunch of large, beige clove polyps that seem to sprout a new head every time I look away. I also have what I think are...

The large colony of my blue zoanthids appear to have some white spots that I think could be Zoa Pox. None of the other zoanthids are showing these symptoms. Also, the smaller frags of the same colony in my 50gal frag tank are not showing these symptoms. Other than having the white spots, the...
