coral health

This is likely to be the dumbest thing I have ever asked in my life but how can I tell if my reef is healthy? Ive been doing this 8-9 years now and haven't lost anything yet but fish but other than my candy canes I don't have the super explosive growth some people see in their reef tanks with my...

I recently bought this frag for $10 but I’m not quite too sure what it is. Also, in the first image (present time) the polyps are down, is this an indication of decreased happiness or too much flow?

Hi Everyone, I thought it would be fun to post the progress of this hammer I was given, it has lost a lot of color and has receded skin. Also feel free to post your own success stories and photos of LPS you have nursed back to health, maybe it will give some hope to those who struggle and may...

Hey all, I just dosed my last bit of Red Sea (RS) magnesium this morning and calcium plus isn’t far behind. Instead of reordering the Red Sea I’ve had my eye on the Tropic Marin ALL-FOR-REEF BRS has some great reviews and it’s been sold out during covid times. I’m wondering what folks think...

What would you add/change? 3 month old 20g. The orange sponge has been receding since the beginning and there seems to be some bleaching so I’ve cut the light back from 14 hours a day to 10. Also the light gradually increases to 80 percent and then back to zero except the blue light is left...

About 2 weeks ago I obtained a basically dead Goni frag (not more than little green dots in the skeleton) that had died off when the tank's nitrates skyrocketed (at least 100ppm, if I'm not mistaken). Well, I took the little guy and put him in the corner of my 20G where the flow was moderate...

So let me give a little background. I started this hobby for the first time about 7 months ago. I knew starting out this hobby would be a challenge, but it was something I was ready for. I cleaned out a JBJ45 I picked off Craigslist, set it up. Cycled for 2 weeks using a combo of live sand and...

Hi everyone, so I've found myself kinda in a conundrum and trying to think possible solutions. So I have a frag rack that I've been using to put corals on while acclimating, but a problem I've found is controlling algae growth on the rack itself. Obviously it's too high for crabs, I stick a...

So I just got my bubble coral shipped to me along with other corals. All my other corals are doing fine, but I’ve never experienced a bubble coral before. I know they are very fragile and can pop easy. Mine has yet to open up and doesn’t look very happy. Is this how they normally look or should...

Hi guys, I filmed a few species of the Acropora I keep to see what their response was to being target fed Ocean Nutrition's 'Reef Pulse'. The Acropora didn't seem to directly ingest any of the food, but did capture some, only to release it with mucus a few moments after being filmed. I will be...

Hey everyone! So really at a loss on this one, but got these clove polyps about 2 months ago and they've been great open and out. About a week ago they closed up for some reason and I thought may have something to do with lighting as I was already looking to upgrade. Switched lights and still...

So I hadn't noticed this before, but tonight saw these white almost rings coming off my frogspawn. Not sure but they look like worms. Is this something I need to worry about?

Hello I’ve had my tank for about 6 months and recently added some corals. They seemed to be doing fine the first few weeks. I recently had a brown algae bloom, but it settled down after changing my lighting schedule. One of my zoa colonies have closed up a bit and I noticed brown stringy stuff...

Hey everyone I am new to the hobby but I am retired and do a ton of reading and research however I am lacking in my coral knowledge but I will get it down soon. Please provide some guidance and or suggestions for my tank. I will attach pictures for your punishment. My main question is for my...

This morning I noticed these small white bumps on my coral and I have no idea what it is I’ve had it for around 2 weeks and it always stays open and eats fine. Is something wrong I checked my tank parameters and they where all ok. I have two zoan frags one duncun and one torch all have at least...

just wondering how it looks coming along. 3 weeks old vs 3 months old
