bleaching

New here, hello. I'm running a 150 gallon mixed reef with a 55 gallon sump. It's been up for 2 years but just started adding coral about a month ago. Running 36" dsuny leds and 6 t5's. Before I added coral I turned off the t5's and reduced intensity of the leds to 45%. This is what was added...

Hi all, not new here, but first thread start. I just noticed yesterday something I've dealt with before and so here is what I saw leading up to finding acro eating flatworms, how I identified the issue, and how I have intially dealt with it. The last few weeks I've noticed some of my acros...

Goodmorning, I just bought two lps on Sunday, a hammer and a chalice. It did well the it ate a pretty large amount of food on Monday, but on Tuesday i noticed two white spots on edge of the coral. I also noticed a hermit crab next to it but it was scavenging on the dry rocks. I observed it...

My elegance has white tips is this new growth or bleaching

i ended up adding a piece of my bubblegum digi to my tank last week as well as my sunfire grafted cap, and they started to bleach within a couple of days. I also started to notice my acros losing tissue on their tips within a couple of days after that. I immediately tested everything and my...

I bought this red/orange montipora a week ago. Tank chemistry seems fine - no high phosphates or nitrates and no ammonia. Is it growing or bleaching?

Hello everyone, I have had my tank for 2 years and my montipora have been growing like crazy. Everything was perfect. Last week I noticed a gonipora was closed up so I decided to do a large water change. It's a 150 gallon tank. I usually do 30 gallon changes. I did a 75 gallon change...

Hey guys, i had a tank crash last week because of a failed return pump. Whole tank went cloudy and i lost some corals, fish and inverts. The one coral that didnt make it was my whole colony of anthelia. 8x6 inch colony disintegrated into a smelly mush on the 3rd day of the crash. I only got it...

I am having serious problems keeping certain SPS and LPS coral alive. My tank is around 2 years old now, and I have had huge success in keeping soft corals and zoas, but any LPS or SPS coral that I get usually lose their flesh. Montis, Acros, Acans.....they all look great when they go into the...

Background Classification All of the hard corals fall under the order, Scleractinia, which falls under the subclass Hexacorallia. Hexacorallia is under the class, Anthozoa, within the phylum, Cnidaria. So, when we talk about SPS coral, some people say, "small polyp stony" coral, while others...

I just bought some great corals from @acro-ed , but as soon as I started acclimating them to the tank, it appeared my blenny was nipping at them. I figured he was just going after algae, but could not see any algae on the acropora at all. Fast forward to today, several of the acros are...

Hello!, This is my first gorgonian, I got it a few days ago. It seems to be shedding today? And these rigid little bumps are showing on its arms. This one is photosynthetic I was told, any tips would be appreciated. Alk 9.2 Cal 440 Mag 1380 Nitrate 5 Phos 0.06 1.025 Pic when I first got...

Here is the short version. I have 4 anemones in my tank. 2 are doing really good and the other 2 seem to be bleaching out. Why? Long version (if you're still interested in helping me): I have 4 anemones. Two are rose bubble tips and they have been doing great for a few months now. The two other...

Hi everyone, I have several montiporas, a pocillipora, two bizarro, and an a can that seem to be slowly withering away on me. They were doing well for awhile and had growth, but now they’re tissue seems to be receding starting primarily at their bases and then working up. I have a hair algae...

I bought a rose BTA from a lfs a month ago and it has been doing great. Readily eating pieces of shrimp i feed a couple times weekly, and expanding to about 5 inches with great bubbles. However I notice that when he really stretches out, if you look close you can see through the orange tentacles...

About a month ago my local reef club was doing a raffle and I ended up winning a grafted monti. I am fairly new to reefing, but the guy who gave it to me that if I slowly work the frag up to the upper most rock in my tank that I should be okay. This is because I only have a current USA orbit for...

Hey all, My coraline algae that was once purpleish, is now bleaching white or a faded grey. I'm assuming it's my lighting because parts that have less light are still purple. Behind my anemone when it shrinks up, the coraline is still purple behind it. It started with white spots taking...
