Royal gramma acting strange

Ok reefers I need some help. I’m a newbie, this is my first tank and it’s about 10 months old. This gramma is about 8 months old. We had a fairy wrasse that was a bit of a good bully, so we would really go weeks without seeing the gramma at all. We got rid of the wrasse, and she started coming out, but this was the result. She’s been swimming like this, or sometimes she just lays on the sand. Salinity and calcium were high this morning.
Parameters before a 15-20 gallon water change.
Salinity 1.0275-1.028
Ph 8.4
Magnesium 1265 ppm
Phosphate .18 ppm
Ammonia .06 ppm
Nitrate 16.7 ppm
Alkalinity 9.0 dKH
Calcium is a blinking 600 ppm on the Hanna tester. I’ve tested it twice to make sure.
Several hours after water change:
Salinity 1.0265-1.027
Alkalinity 9.2 dKH
Calcium 525 ppm
Calcium finally registered something.
I didn’t do full testing, just what I felt was important. I haven’t seen it eat at all in the last week, and shies away when I try and put thawed shrimp in front of it. I’ve set up a hospital tank, but I don’t want to stress it with moving if I can help it. Any thoughts?

Feels like a different tank when the sunset lights are on

The last 45-60min of the day feel like a different tank as the lights dim to the west, and all the fish have gone into hiding.

Wanted to show the tank, figured I would take time to answer any questions to people who want to know more / new to or exploring reef tank hobby.

I always seek ways to simplify my setup and protocols.

I've been letting Hair Algae grow out on the back of my tank and the way it moves and shimmers in the light is so nice to look at. Also found a tiny pistol shrimp living in it so I haven't disturbed the growth in a few weeks now.

What's your worst "if only I'd caught it sooner" story?

I know I'm not the only one. What's the thing you missed that still bothers you? Fish acting weird for days before you noticed? Algae taking over while you were busy? A heater failure you caught too late?

Genuinely curious what the most painful blind spots are in this hobby. The stuff where you think "if someone had just told me on day one..."

Saltwater Pond Update

Been awhile since last posting. Summer was absolutely brutal on the farm. Lost a good bit of colonies from the heat swings. Birdsnest all died and so did the giant stunner chalice. The result was the chemistry of the system being completely thrown off for a couple of months. We’re still recovering, but when things like this happen we always bounce back better than before. We’ve been taking steps to make sure the system won’t experience temp swings like that, and I’ve taken the opportunity to really dial in the chemistry. So needless to say the saltwater pond needed a reboot. Took out 50 large Bangai cardinals and about 100 babies, cleaned the sandbed, and changed the rockwork to allow more flow and no dead zones. Overall it’s settled in very nicely and the corals are doing great. The best thing is that now that its not 60% birdsnest, the fish are way easier to appreciate.

So…. Bought a crud cup from the coral farm

If any of you are familiar with the coral farm in mass, they sell these things called crud cups. Basically some rock, pieces of whatever mixed in, and they sell them.

I bought two. Wasn’t sure what to expect, but im actually impressed. This is a few days after dumping the crud cups into a mushroom box and running it in my sump. Photo has been color corrected because of the blue light in the sump but it’s almost spot on.

Now what the heck do I do with this stuff? Can I glue these things onto frag plugs or just let them attach to rock and then just move them into the tank? Thanks in advance.

Dr. Tims Re-Fresh is attempting to crash my tank

My tank has been thriving corals growing like crazy and healthy fish. I have been battling a little cyano and after doing some research decided to add a new type of bacteria. Iv only ever dosed nitrifying bacteria. Last night I did my normal water change and did less than the recommended dose of re-fresh. When I woke up this morning I noticed a couple dead snails and all my corals extremely retracted. Fish very lethargic and the rock dwellers completely hidden. I immediately tested for ammonia which showed 0 and salinity was good. I added a bubbler to help with oxygen. By the time I got home tonight my birdsnest was peeling away. Tested ammonia again and was up past .5. Added some ammonia stabilizer and another water change.

I can only assume there was a massive bloom which sucked the oxygen out of everything and stalled out my nitrifying bacteria.

On top of that I got my first ICP back today that I did for fun and found I have extremely high levels of Antimony.

Any thoughts, help, or ideas are welcomed!

Coral ID

This was a donor tank that I fixed up decently well. After around a month or 2 after getting I found some coral loosely attached to a rock and I decided to glue it down. The donor doesn’t remember what coral it was, so now I’ve turned over to Reddit.

This guys is so damn cool looking. Just added to the tank a few days ago, but it’s on the verge of full polyp extension.

Building ReefShield Aquatics | Part 2: The Fish Room Is Taking Shape

It’s been a little while since our last post, so I figured it was time for another ReefShield Aquatics update! I've been super busy with life recently, so it's been a little longer than I had planned.

We’re now about one month away from closing on the house, which means we’re getting very close to the point where this stops being a construction project for our builder and starts becoming a real fish room project for me!

The basement is basically complete and this is the state we will be inheriting it in. A little bit of drywall, exposed ceiling joists, and a whole lot of open space. Behind the scenes, a ton has happened since the first post. The electrical, plumbing, HVAC, and other mechanical systems are now in place, and we recently passed our rough building inspection. This is the part of the build where a lot of the work isn't fish focused, but it's laying the foundation for everything that comes later.

Once we close, then the fun part begins! We're getting close...

While we've been waiting, I've been using the time to plan out as much as possible so that I can hit the ground running once we get the keys.

I've been working through the tank layouts, quarantine systems, filtration, RODI / saltwater stations, water-change systems, electrical/equipment locations, storage, humidity control, and probably about a thousand other little details.

I'm trying to solve as many problems as possible before I start putting tanks and equipment in the room. I'm sure I'll still make plenty of mistakes, but hopefully I can avoid some of the really expensive ones.

Does anyone have any cool ideas I should consider before I get started?

First time reefer, need advice!

I have had tons of freshwater fish throughout the years and have been incredibly successful and now I want to get into saltwater because at this point I honestly find the saltwater tanks more appealing. I know most people say you should start large because its a lot easier to keep it stable but I am going to college soon and they have a limit of 10 gallons for any pet fish rule. I want to get a reef tank that I can bring with me that is an all in one setup. Do yall have any suggestions? I was looking at the fluval evo V but it just seems a little too small tbh. Any suggestions would be great. Also what corals do y'all suggest that would be colorful and not outgrow the space I put them in. Additionally what could I put in the tank besides maybe a clown, a shrimp, some crabs, and snails?

Any suggestions y'all have or resources that could help me learn would ne great, thanks!

Custom build aquarium

Hi All,

Couple of weeks ago I have opened a thread, asking for opinion for Red Sea 250 G3 MAX. With all the comments , I have decided that it is not worth the risk. Now I have couple of choices - to wait for the Red Sea new line reef-frame (I assume with the euro brace it will be more strong) or to go with the path for custom build. Purchasing all the other brands that you guys suggested , unfortunately it is not possible in Bulgaria.

That said, does anyone have exact dimensions of the sump of Red Sea reefer 250 and all the chambers?

I would like to copy the exact dimensions, with a slight addition - to include refugium .

Thank you for all the support!

What's wrong with my clownfish's poop?

Hey guys, I went on a trip recently and left my clownfish in the care of a friend. When I got back, I noticed their poop looks really weird. It's this brown, stringy filament-like stuff coming out of them.

They're acting completely normal and eating normally, but it looks like they're bothered by it. They sometimes try to rub themselves against the rocks or move around trying to get it off.

Does anyone know what this could be? And what should I do to help them?
