Currently setting up a nano reef and have a bunch of holestone laying around (never used). Is this stuff usable in a reef tank? Anyone has any experiences with this stone?

Hi guys, This is my first post ever :oops: sorry for any dumb questions! I am new to Reef World and I've started my first cycle in a blue marine 30g tank with a back AIO sump. I've bought the Red Sea Mature Starter Kit and I've been following the day-by-day guide. Right now I am on Day 10...

Pictures say it all. I am facing a dinoflaggelate that keeps attacking SPS and other corals such as Pectinia. At first, there are pronounced mesenterial filaments, then the tip turns white, then it loses tissue and finally brown dusting appears. There are no strings and only some bubbling...

Hello fellow reefers! I have a few colonies of zoas which are doing amazing but one particular zoa has been getting smaller rather than bigger despite other corals showing no signs of stress… change in lighting is due to the lens I’m using not the actual light. Bluer photo is before, whiter...

Hey all!! I've been eyeing the Fluval Evo 13.5 as my first reef tank, and I've been trying to get an idea on what I wanna stock it with. So far I have the idea of 2 clownfish, an Orchid Dottyback, and some Trochus Snails. I was thinking of adding a cleaner shrimp as well, but I wanted to get...

This is going to be a multi-part question... My husband went to our LFS a couple of weeks ago and brought home a powder blue and a powder brown tang.. The powder blue is a little smaller than the brown. The LFS owner had told him that she had never had any issues with the two together as long...

I have two frags of gsp ones quite small while the other one is a large lump with strands about 2 inches in length I had got this Halloween crab about 3 days ago and today he went on the rock for the first time I've seen and literally went straight for the small lump of gsp, and started eating...

I'm upgrading to a 125 with trigger system 32 sump/refugium. Was experimenting with how quickly I could cycle so tried the following: - 120 pounds of live sand (crushed coral ~3in) - 135lbs of live rock from a 15 year old system. tons of stuff i've observed on these rocks including some ugly...

Hello, I have been dealing with ulva in my DT for a couple of months now, and I cannot seem to get rid of it. I have a tang, snails, and emerald crabs. None of them seem to want to eat it. Does anyone have any other solutions?

I have an MP 60 that I got a week ago and used for 1 week. I have all the packaging as well. I purchased it new from BRS. My tank has a black acrylic sheet glued to the back on top of my 1/2” glass. I got the MP60 because it would stick better. However, it’s way too strong for my tank and I...

Is my reefmat running fine ? I have a 90g tank with 7 fishes in an established tank that’s been running for a couple years . I’m only averaging 1.4 cm a day

Anyone able to identify what this is? I don’t really know how to describe it other than it looks like cotton balls on my coral. Guessing some sort of fungus? 14 gallon reef AIO, pretty new to all of this so any help is appreciated!

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...

Hello! I wanted to get some input on stocking ideas for my 60-gallon reef tank. Right now it's mainly empty (just a clownfish and royal gramma) and a bunch of corals. The tank itself is pretty well-established and I'm considering getting a more 'finicky' fish but can't seem to make up my mind...

Hello all, My ORA Red goniopora has not been thriving the last few months. After I purchased it, it grew exceptionally well and was always very extended. I’ve had it through a variety of conditions, including alk anywhere between 5 and 14 at various points. My parameters are very stable now...

1) Fiji Cube 20 Peninsula Pro 2) Innovative Marine Fusion Pro 2 20 gal 3) Innovative Marine Fusion Pro 2 Lagoon - 25 gal Peninsula was the preference, but I like the build and look of the IM and the extra width of the IM lagoon.
