Hey everyone! After over 2 decades of keeping freshwater planted tanks (which I still have and love), I finally decided to dive head first into the reef keeping hobby with my older 11 year old son. We’ve had our tank up and running for about 4 weeks now with live rock from our LFS (Red Sea MAX...

Hi there, I have the weirdest thing going on with my hammer coral. I have a gold branching hammer that is growing in a weird way. Its new heads are growing as if they were some wacky wall hammer. One of the heads is growing skeleton, but is only attached to the colony by tissue...

Hi all i bought a acropora about a month and a half ago looking like this and today i noticed white tips like this Is that a sign of growth?

Most of my corals are flourishing and doing fantastic. However, I have a few that are struggling or have retracted over the past month. Namely: Platygyra, Candy Cane, Chalice. But the others in that list have just closed some of the polyps or the new grown turned white and died off. For example...

Hi guys, I have been scouring the threads for awhile now, in search for potential solutions. This is my first post and I have finally decided to ask for some help. I have a 180 gallon reef aquarium I bought second hand. I have owned the tank for about 2 years or so now. I started with wet rock...

Here is my 28g tank. It’s a JBJ Nanocube (currently battling some derbesia/bryopsis).

So I currently have 2 zetlights 1201a https://www.bulkreefsupply.com/za-1201-aqua-system-series-pico-led-light-zetlight.html hook on to my 29 gallon reef tank, mostly low light lps and zoas what setting should i have set for optimal coral growth?

Now to start don't get me wrong I believe first comes husbandry. But I've been doing a lot of research recently about Kelvin with reef lights, and I'm curious to see what other reefers use for their reef tanks. I'd like to know if you have found any differences between 10k vs 14k to even 20k...

Earlier this year, I lost a super cool Pocillopora colony that had spontaneously grown on and entirely over a Random Flow Generator® Nozzle. Sadly, due to a return pump failure, It was exposed to the air for just a little too long and the top half didn’t make it. So I pulled the entire RFG...

Hey guys, I tested my tank today and the results were Alk : 11.5 Cal : 440 Mag : 1440 NO3 : 10 ppm PO4 : 0.25 I haven’t seen any noticeable growth from my corals, I keep all softies but added my first LPS yesterday, which is doing great so far. My zoas closed up after being opened since I...

So I have a green star polyp and I can’t tell if this is normal? Or if it got damaged it looks super healthy and I have had it for almost a year if anyone has input that would be awesome. It seems like the circled area is longer and or like puffy looking.

My trumpet has been acting strange for the past year or so. It had a big spike of growth last year with 6 heads growing and very fleshy. Now it is very shriveled and not getting any growth, but not receding or showing any signs of sickness. Could anyone explain this? Parameters: alk: 7 Calcium...

Hello, I have a biocube 32g and I have not noticed very much growth in my corals and have heard/read it could be because of my light schedule. My current light schedule is for the pink (sun rise) lights to come on at 9:30am-10:00am. My whites come on at 10:00am and are on until 5:00pm. My sunset...

There’s probably a post out there like this, but I wanted to create a thread to get specific answers for this question and hopefully help some others out along the way. I have been trying to tune in my AI Prime 16 HD over my Fluval Evo 13.5 for some time now. I’m slowly sorting out all of my...

So I've heard and read a lot of different things on ways to help with coral coloration and tried many, just have yet to find any amazing results. Here's a little back story on what I've tried along with current parameters: Tank: 45g JBJ AIO Light: Hydra 52 (I run 16k at 30% with a 1 hr ramp up...

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...
