new

Hey guys! For sale is a brand new in box Synergy Shadow overflow, I just don't need it. The only very minor issue is that I had this stored in my garage, I left the garage door open one day, and a little bit of rain got on the box. So the box got just a little discolored, but the box is still...

Hey, new to the hobby here, tanks about 3 months old, I have a pair of clowns, the female has been pretty aggressive with the male, nipping his fins and such so I separated him in a little isolation box so he could relax for a few days, as I do not have a separate tank, but now the spots I...

Anyone able to ID these? First is a fleshy like lump with a red mouth like feature attached to my live rock, idk if it’s always been there but as some of my sea squirts fell off from pesky crabs is when I’ve noticed it. Bellow the bubble tip nem surrounded by the red. I’m unsure about this...

Hello! Bear with me. I am new to saltwater aquariums and testing, any help is appreciated. I’m testing for Alkalinity using the Hanna tester. I followed the directions and got 6.4 and 6.0. These were back to back tests. I then used a Salifert calcium test and got 400ppm. I trust this one more...

Hi all! I've been given two small corals for my tank when purchasing my Blenny yesterday, and I was wondering if anyone can help with first of all what they are, and second of all what is happening with the tree coral? It seems to just be folded over.. I am super new to this and these are the...

Of course im new to the hobby, my tanks is 4 months old. I’m running a 80 Gal redsea G2, with two reef led 90s, reef mat, skimmer and Red Sea reef spec carbon. I religiously do a 10% water change weekly and all my numbers have been steady. I think I understand the ugly phase but I don’t know how...

Impulsively went to my LFS and immediately knew I needed to start my very own reef tank. I’ve had a betta before, but that was nothing compared to this. Currently I’m a month and a half in with no issues once so ever. I wanted to do something with puffer fish, eels, and sea horses but some...

I know every tank is different and I've watched tons of the BRS videos on starting new tanks / ugly stages / etc. But I'm trying to be mentally prepared for the next "Shoe to drop" with this tank. We're a little more than 2 months in on our first 90 gal, and seem to be getting to the end of...

Hey everyone! This november will mark my 1 year in the world of saltwater! I feel as though I have a good grasp of it all, and now I'm trying to meet more people in the hobby/learn how to navigate this website! (Super cool although overwhelming). Attached are some of my favorite photos of my...

New to me but hopefully not new to others. Help in the ID of these two critters? Never noticed them until this week. Long striped strings/tentacles from the rock in multiple spots. Little guy keeps slowly coming up then shoots back down anytime I get close except for if I stay for a while.

Main tank is 2 months old (live rock start). Ugly stage is fully present and brown haze is settled in and made itself right at home. Awesome, love it, so fun. But, picked up some more fish from @Biota_Marine , a Link's & a Court Jester Goby and a Royal Gramma. I have them in a 24 gal QT...

Hello! Was curious if this was bubble algae that came with my Frogspawn frag I got today? If so, what’s the best way to get rid of it? If not then what could it be? The bubble like substance by my thumb. Dark in color. I didn’t dip my coral so maybe this was my first mistake..

Hello all. Today I purchased my first lobo coral from my lfs. I didn’t notice it in the shop but just got it home gone through acclimation and a coral rx dip and I see this on the base. It’s green and a different colour to the lobo. It shows fluorescence under a UV light and appears to be either...

Hey all, I am just doing research into starting up a mixed reef in a aqua one minireef 160 and I was just wondering what would be an adequate lighting upgrade. I plan to start off with livestock first (stocking to be determined) so the included 40w led should be sufficient until I upgrade later...

Hi I'm going through the ugly stage now and my tank has 2 clowns and no corals (yet). Is there a way to end the ugly stage early or speed it up

New 90 gallon tank w/ 20 gallon sump (3 weeks old). Started testing Calcium with API kit and seeing (fast) linear drop. Just trying to understand why it's moving so fast and whether this is something I should address via Reef Fusion 2 part additives. Current Livestock & Date Installed...

Hello! I'm brand new to saltwater tanks, but I do have two freshwater! I've always admired saltwater tanks, but they were somehow always too intimidating for me to start. I've just gotten a 14 gal nano tank and I've decided to take the plunge! A lot of things I search for point to this site...
