reeftank

Hey everyone, I’m pretty new to the reefing side of the hobby and still in the planning / early setup stage. I’ve been doing a lot of reading and watching videos, but honestly it feels like there’s so many different ways to do things 😅 Right now I’m trying to keep things simple and not rush it...

I have not found a reeftank app I like yet. I want one that sets reminders or daily to do lists, that you can check off after notification. As well as track all tank parameters with easy input, which over time creates graphs. I am messing around with AI and building one, but I am curious what...

I've officially made the leap into saltwater! About a year ago I got into the aquarium hobby and built a 75g freshwater tank in my office. It's been a great learning experience and the tank is doing really well. Recently a buddy of mine (and his dad) showed me their saltwater setups and, well…...

Five-Month Full Tank Record This tank originally didn’t have many issues with the aquascaping that I was dissatisfied with. However, the constant collapse of the scape forced me to break down and rebuild it. The most painful part was having to restart with the corals that had already formed a...

How's your tank build going?

I’m new to saltwater aquariums. I received corals two weeks ago and they’re still in my corantine tank. Recently, I’ve started seeing a small creature. I’m not sure if it’s a flatworm, copopod, or something else. Could you please help me identify it? Is it safe? Should I remove it to prevent it...

Hey other reefers, I just picked up a 300xl and noticed after setting it up a chip on the front glass at the bottom of the tank…. I packed silicon into the area and tried putting some on the inside in a panic. I’m not sure if I should trust it long term, what do you guys think?

Hey y'all, (Back story) New reefer here, been in fresh for over 20+ years though. 40 gallon saltwater Aqua Top (tank is now 5 months old) is where the question relates. All levels are stable Tank does not look like the pictures anymore. Buddy of mine finally got me into saltwater. Here is...

Hello to everyone! I’m new here and new to reef keeping but not new to aquariums in general as I had my first FW tank back in 2009. This year I tried something new, so I’ve got an 8 gallon cube tank. The Aquael Nano Reef 30. I changed the light with a new LED light fixture suitable for reef...

Hello!!! This is my first time plumbing an overflow/sump. It is a predrilled tank with 2 holes at the bottom of the overflow. I’m attempting to run it as safe as possible (preventing overflows), but there is no room to drill a 3rd hole. Previous owner ran the tank with one drain and one return...

Chill~ enjoy it

Hello, I am currently seeking lobster eggs to feed my Mandarin dragonet, as I aim to fatten him up. Unfortunately, I have encountered difficulties locating this specific food item. I have inquired at local retailers such as Petco, PetSmart, and my local fish store, but they have been unable to...

I recently got a 90 gallon tank to upgrade my 30 gallon right now. I’m gonna need some more lighting and was wondering what would be good. I was looking at the NICREW 150W Aquarium LED Reef Light on Amazon and would get 2 of them but I’m not sure how good they would be. I’m kinda on a budget as...
