sps advice

Hello fellow reefers. Two days ago I noticed this WWC Crimson Stylocoeniella had some polyp damage on the top of the original frag / colony that has since encrusted down onto the rock it's mounted on. The structure it's mounted to is a floating shelf with a vertical face attached to the glass...

Hi everyone! I’ve been following Reef2Reef for quite some time and have learned a lot from the discussions here. Currently, the tank is in a good place overall, and this build thread is mainly about enjoying the process, sharing the journey, and continuing to learn along the way as I work toward...

I’m setting up a 4 feet sps dominant tank, and i’m not sure how many mp40s i should get. The information vortech provide just doesn’t mention what tank size they are suited for. So do y’all think 4 mp40 on a 4 feet is overkill?

Hi all sorry for the long post, I have a Cade 1500 S2 that I purchased second-hand from fakebook around a year ago to upgrade from a Waterbox 90.1. For the first 9 or so months I have had no issues with the tank, and transferred the majority of my live coral and corals across to the larger...

Hi everyone, I’m running a Waterbox 190.5 with 3 Radion XR30s at 50% intensity. I recently started adding a few acros and a monti, but they aren’t doing great—no polyp extension, and my encrusting monti is starting to lose color. I also had my nutrients bottomed out and stayed that way for 3...

Hey Fellow Reefers, I am looking to buy a few acropora/milli frags online. My tank parameters are pretty stable day to day, I have been testing everyday since inception, tank has been up 7 weeks. My PH stays at 7.8, I have seen it go to 8.0, but it is typically 7.8. I bought a doser for...

I will try and be as detailed as possible but feel free to ask more questions. I want to do this tank right. With over a score of knowledge in the community, I am hoping to get the advice needed to make year 1 and beyond as successful as possible. The plan: 32 gal EXT by Fiji cube , complete...

Hi All, On one side of my aquarium, my Monti's, Acros are just bleaching overnight. Parameters have been stable for years, Triton tests are perfect and nothing has really changed in terms of flow and lighting. It started off with one Monti, a couple of weeks ago, Now more corals are dying in...

Help! I’ve been having issues with SPS for months now. Every SPS I introduce to the tank develops RTN within 48 hours. All of my LPS corals are doing fine. Even this coral has good polyp extension when in the water. I have not seen any pests on them, but i could just be overlooking. I added this...

Hello everyone, Im a new member here, but Ive been in the hobby for years. Im looking to upgrade the lighting on my 4-year-old 75-gallon reef tank. Currently, Im using a Fluval Sea, which has been fine for softies, but I want to start keeping SPS. Unfortunately, all my previous attempts with...

I would love to hear about this from experienced reef keepers and what you think about keeping both together?

Howdy! I went on vacation for one week over the holidays and everything was fine when I returned except for my monti frag that I’ve had for about a month or two now. It has this white look to it now on about 75% of it, but I can still kind of see color under it. It doesn’t come loose or off when...

Hoping for some more eyes on this to help me nail down what's wrong with my green goddess birdsnest. She was doing great for months after a rocky start in Nov where it lost over 90% of it's polyps after accidental exposure to RO water during the initial introduction to the tank. (noob move on...

Hello my name is Andres Guzzi AKA acropora_mx on instagram , I love acropora and the main reason why I started my IG page was to learn the names of the Acroporas and to know the different morphologies that exist in the Acroporas, and today I have met many new people and learned many new things...

Hi All! I have a 40 Gal tank that was FOWLR since November until Friday when I added this leather toadstool. It looks like this and I want to know if I need to be worried or not!? It was laying like this on the rock I initially had it on so I moved it lower thinking it was getting too much...

I had an established 4 year old 425l mixed reef tank that sprung a leak, and by necessity had to create a smaller setup in a 250l tank with no substrate, which was running for about 4 weeks. Now I have a 625l and have transferred all coral and fish, this time using sand with live bacteria as...

I often find myself looking online for inspiration for my reef tank that I’m gonna be setting up. I see a lot of tanks that are super mature and grown in and the corals are just absolutely packed into the tank. I’m talking like 15 corals on a rock. How is this possible? Are coral stings not as...

There have been far (far) too many threads and websites discussing best beginner SPS - you know, the typical green slimer, monti, stylo, birdnest discussion. How much can we kick a dead horse? That bad boy is done and cooked. We all know where to start, but where do we go from here?! I have...

Looking for help/ ideas A few weeks ago a purple stylo had retracted polyps, now it’s spread to almost all sps. Parameters are ok pH is 8.0 kH is 8.9 Ca+ is 430 Mg is 1301 Ammonia 0 Nitrite 0 Nitrate 5 Phosphate.12 Was running UV 24/7. Now it is off Was running Refugium 24/7 now just 10 hours...

Hello I've recently just setup a 150gallon tank that I'm looking to make primarily an SPS Reef. I do already have a few fish for it that have been in my 40g macro tank for the last 2 months. Those fish are a pair of SixLine Wrasse and two Aiptasia eating Filefish. The one fish that I really...

What’s going on fellow reefers! Planning a new 10 gallon tank for the office. Flow, thinking 2 koralia 240’s and my aquaclear 110 Hydor Koralia Nano Aquarium Circulation Pump, Includes Built-In Cable Protector, 240 GPH, Measures 2.4-Inches & is Ideal for Fresh or Salt Water Use...

I have a fair bit of Brownish colored algae in my tank on my sand and green algae on my rocks. It’s a new tank cycled for about 2 months, but livestock only added 3 weeks ago. 15 gallon nano with SPS. a few snails and hermits cleaner shrimp clown and 6 line I am wondering if I should add a...

My parameters are all normal -0 Ammonia -0 Trite -0 Trate -1.025 -77.5 degrees -AI Prime HD set to SPS AP+ spectrum -AI Nero3 pump set to random mode between 3% min and 20% max with medium variance, and it blows straight at the back rocks and diffuses it everywhere along with return pump flow...

Hi! Recently out of the blue my SPS corals are turning white, and some of them have a reddish-brown color. Not sure what is causing issues, some stats are: Temperature: 79.3 F NO3: 13-12 pH: 8.2 PO4: 0.07

About 2 weeks ago I moved all of my corals from my 20 long to my new 50 gallon system. Parameters were the sam and I adjusted the lights to the same par value the corals were used to in the old system. I had noticed over the past week that my orange monticap has been losing tissue a little bit...
