reef

So I have kept freshwater tanks for a while and I have enjoyed it but I have been very interested in doing a reef since before I started freshwater. I guess I wanted the practice of the routine first. My only difficulty was easing my partner into being around fish tanks and getting a tank big...

As the title says, I'm looking for some advice on keeping a tall reef tank - I'd love a 1000mm tall tank by 1000mm wide or a 750mm by 1000mm wide. I understand the maintenance side of it will not be easy, but what about lighting the tank? From what I can find online, Kessil seem to be the...

Assuming you don’t have direct access to the ocean but resources aren’t an issue, what would be the easiest way to build/get a stable reef system? Automatically things like water changes via buckets get eliminated and other methods like auto water changes or reef moonshiners/triton come into...

***Located in Huntington Beach, CA, Orange County, SOCAL*** ***Pick Up Only*** Hi I got this as a b day gift but I already got a WaterBox. Is anyone interested? Asking $140 It's brand new in the box.

So I've had some softies in my tank for 2 months now and they were initially doing great. But now I fear some of my fish may have started nipping them and they look awful. I'm pretty sure they've been nipping them cause I've seen fluorescent coral bits in the sand before which I assume are from...

Tank is 180gallon. 18 months old, started from dry rock and sand. All sps. Everything was doing ok, not the best growth but growth until late March. The Acropora started to die off. My Montipora frags still are growing but at this point I lost around a dozen frags. Around that time I did switch...

Just a video of some of the corals, fish, and inverts in one of our tanks! They make for a colorful aquascape!

Just wanted to give a shoutout to all the reef-keeping dads out there. Whether your "kids" are two-legged or have fins, gills, and a tendency to knock over your aquascape at 3 a.m. To the fish dads who: Lovingly turkey baste uneaten food like it’s a gourmet cleanup… Build custom frag racks...

Does anyone have the file for a 3D print, for this wave maker/pump. To print an extra/overlaying guard. Voyager HP 9 Stream Pump (3600 GPH) I have lost to many fish for this to keep happening. BRS told me I can 3D print an extra guard, but I don’t have the file. I’m hoping someone here does...

Hello! About a month ago I was struggling with Dinos, but my tank bounced back and is doing so good now, noticeable coral growth. However, bubble algae has started to take over, some of which looks to be growing on top of some corals. I have been manually removing it about twice a week, using a...

I want to get an octopus but don’t know if that is a wise choice. Do they really have a conscious mind and knows they are being boxed in? I’ve seen what appears happy octopus on social media. Do they have short lives? Anyone have an octopus or know about keeping them?

Okay I check everything chemicals in there it's stable and the water temperature is good range and stable i don't know something to do with lightning

These are the results from today, same as it was the last time I tested 1.5 years ago. Is there really a benefit to testing these parameters weekly or monthly if I keep getting the same results every time?

Hey all! Back again with another build thread! I'll be the first to admit—I totally failed at keeping my old 40-gallon Red Sea thread updated, BUT I will say it's been running strong for over a year now and looks awesome! That said, we're not here to talk about the 40. We're here because...

With the Saving Nemo act being reintroduced, how do you feel that it will affect our hobby and the ocean in general?

Howdy everyone, and thank you for having me. I am trying to find stocking for my 20g reef tank, but unsure where to go. I am set on a purple firefish, but uncertain what else to do. I am not a fan of clowns, so I will not be going that route. Thank you in advance!

I’m upgrading my small tank and need to find a new home for this one. It’s a 14 gallon (15” x 15” x 15”) Aqueon rimless cube, and comes with the lid (diy mesh lid), rock and coral you see in the picture. I’m keeping the fish, sand and equipment for the new tank. The rocks are glued together...

Hey everyone. I’ve been reefing for a while now—currently running a tank I’m really proud of—and lately I’ve been thinking about how this hobby intersects with what I do for work. I’m work in graphic design and I’ve started wondering: Is there space in this community for more intentional...

Hey All, new here and slightly new to saltwater tanks, I rescued a huge collection of equipment and some animals from a hoarder, long story short I wound up with a saltwater tank that I didn't necessarily plan for or need. Anyways, my problem is that my pH will not seem to remain over 8.0 and my...
