coral growth

I am moving my waterbox 90 to a new waterbox 230. It is a mixed reef tank with about 14 fish inverts SPS LPS and softies. Any suggestions the best way to do this? I bought new chandler tock and want to bring my old rock over as well. Also I have used continuum supplement for coral growth and...

Hey all! Finally joined this awesome community and apologies in advance if i have posted in the wrong thread etc. A few of you may have been following along on this build but it recently hit the 12 month mark and i was reflecting on this little experiment. I wanted to see if coral would grow...

Hello everyone, my name is Nik and I’m from little Switzerland. I’ve been on the forum for a while now and I’ve learned quite a lot thanks to many of you. It’s always interesting here – I really like the community, and you keep giving me new ideas for things to try or improve. So why am I...

I’m looking at the Nicrew gen 2 200 or the SMATFARM 140w. Which would be better? What other options? Budget is max $1k I have a 7 ft long, 2 ft deep and wide. Plan on fish and corals. I’m sure I’m going to start with LPS mainly until I can learn more.

So I started my reefing journey back in maybe August of last year. I’ve been pretty good about testing my nutrients and dosing what was needed etc and of course had a couple of mishaps where Alk or other nutrients were lower than what they should’ve been. However, despite my levels being pretty...

Hello all, I’m having some troubles with the corals in my 65g tank. It’s my first reef, so keep in mind I’m fairly new to this. None of my corals seem to be growing, and I’m really lost as to why. I have lost two corals (Kenya tree and Duncan) for unknown reasons. Other than those, I have some...

3 Kessil A360 WE lights. All cleaned up and in working condition. Had these on a mixed reef for about 2 years and everything thrived! See pictures and video for proof of operation. I do have two gooseneck mounting arms I can include as well for an additional $30 each. Unfortunately moved and...

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...

First coral, showing real signs of growth!!!

Have a 2 month cycled tank with a couple of fish and 3 new corals. 1 each of sps, lps and a mushroom. Will dose AFR after a month or 2 based on test results. Should I any of the below right now? 1. Reef growth - Red sea AB+ Or prodibio bioreef kit or seachem fuel 2. Reef health - Brightwell’s...

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.
