I had a big nitrate spike about a week and half ago where they were off the chart. Flow was bad in my tank and green algae was forming. Since I have fixed the water flow, done 3 water changes between 10-20 gallons each. The nitrates have come down some but are still present, I have fed less to...

I just read some interesting articles related to this hobby. Obviously it's a enterprise that makes 100's of millions of dollars worldwide. There are many lobbyists for this trade and respectively an equal amount against it saying it is killing reefs and sustainable habitats... I definitely...

I know this has been discussed and I have searched but can not get a specific answer. I read a thread on making garlic pure extract and soaking food in it. My last black clown is acting fine but his skin is telling me something else. He appears to be having spots all over to him similar to...

I have this coral, which I don't know the common name to, that has these tentacle looking things coming from it. Are these what touch other rocks or areas and allow for spreading of this coral? All the other polyps open but these just stay long and extended... Forgot to mention it's the coral...

Here is my tank on just about 3 month progress. I want to add one more premium live rock that is long and flat toward the center of all the rocks. I am going more for coral and want more of a base to place coral on.

Hi I read on a post yesterday about bioballs and not to use them or remove them... What does that mean? I thought bioballs help with bacteria or growth needed in your tank... My wet/dry system came with bioballs built in it... What is the verdict on bioballs? I want to get some knowledge on this...

I have a 65 reef tank with a few fish. I had a tang that caught ick and I set up a quarantine tank but it was too late. Today it appears the my 2 clowns lightly have ick. My question is, would it be better to remove my corals from the 65 and just treat that tank for ick that may have fallen on...

I have a tube anemone that I recently moved out of the flow. The outer tube skin appeared to be getting attacked by hermit crabs before I moved it. When it was lifted out of sand it looked as if the tube anemone was ripped. About half of the entire length of the tube is where the rip is at and...

My power company will be doing transformer upgrades in my neighborhood tomorrow from 10am-2pm. In this time frame I will have no power whatsoever. This means my A/C will be off, the tank pumps and power heads will be off as well as lights. Will the fish be ok for these 4 hours or so? Is...

I am looking into some new higher powered lighting for my tank. I want lighting that will be good for coral growing. I was told wave length matters more than watts when growing, then I was told that wattage is most important and 3-4/gallon is ideal for growing all corals. So what is it? I am...

Hello, I just bought my first coral and I put it in the tank and noticed a white slug looking thing on it. Will this harm the coral or anything else in my tank? See attached pic. Thanks!

I tried searching before I posted this. I have heard recently about a bunch of different live rock, like fiji rock, hatian rock, bahamian rock ect. What are the differences in these rocks? Does one help support coral better then the other? Lastly, can I mix the rocks in the tank or is that not...
