oooo good eye. Very likely.

I cannot tell, apologies. I'll need to see a clear picture of the other side of it. It sort of resembles a Chiton but that's a weak ID without seeing the top.

skin bloches ar usually a sign of stress. can you post a clear closeup picture? Do you have live rock or sand in the system?

can you remind me what your water parameters are? how low do they get and how high after you dose? add temp & salinity if you don't mind

I hope you mean stripers.

All internal water pumps will transfer 100% of the power they consume into heating up the water. For example, a water pump consuming a constant 250 watts will heat the tank about the same as a 250 watt water heater that is stuck in the on position. The only ways to reduce the amount of heat...

What specific corals do you have in mind?

Any idea what the actual temperature is? All waterflow will increase water temperature. It's the first law of thermodynamics.

In the first picture I see a type of Bristleworm commonly called a Fire Worm. It's a beneficial detrivores meaning it will clean up scraps of food. Don't touch it with bare hands though because the bristles you see are not legs, they are little slivers that can stick into your skin. I can't...

IIRC Calcium saturation levels are about 250ppm. Therefore, Calcium is severely supersaturated in our reef tanks.

But even in an established tank, Calcium Carbonate will precipitate first on the warmer parts of the tank like the heaters or impeller spindles. The greater the water temperature in a reef the more likely to have Calcium carbonate precipitate. Oolitic sand in the Caribbean forms like underwater...

I would love a chemist's take on why something like Sodium chloride dissolves much faster in hot water and yet Calcium carbonate precipitates much faster in hot water.

We're not trying to dissolve Calcium carbonate. We are trying to slow the reaction of Calcium bonding to Carbonate until we thoroughly dilute the mixture and the Magnesium can start poisoning any crystals that start forming. Calcium carbonate precipitation increases as temperature increases...

The first second the salt mix hits the water is a critical time. If you're pouring the mix into a gallon jug it's probably collecting at the bottom for a second or two before you start agitating it. Even if you're only making a gallon use the bucket. Stir the water vigorously while you are...

Have you considered wall paper?

This is true of all crabs.

apologies, it was just recently brought up for me.

http://tpo.net/anti_gun_senator/#.VfxmPRGAxi2.facebook Long time Anti-Gun Advocate State Senator R.C. Soles, 74, shot one of two intruders at his home just outside Tabor City , N.C. about 5 p.m. Sunday, the prosecutor for the politician's home county said. The intruder, Kyle Blackburn, was taken...

Hard to generate power during a hurricane or a blizzard.

The average water temperature where Ocellaris are most densely populated in the wild is about 86F so 82 - 84 is fine. Just be aware that warmer water contains less oxygen so it wouldn't hurt to have a little extra water circulation near the surface for gas exchange.
