new tank

Hi everyone, I'm Akil from Modern Reef & Euro Corals. I've been reefing for over 30 years. I've made plenty of mistakes along the way, and each one taught me something that became part of my experience. Those lessons became the foundation of this guide. Why I wrote this guide: I want to help...

The corals you keep set the requirement before the tank does. A practical guide to specifying reef lighting, and choosing the fixture that fits your aquarium. AUGUST 26, 2026 Most people start with the tank. How many litres, how many watts, what does a tank this size usually take? It's a...

Hey, i have some questions as a non-rs tank owner for those with experience. Ive seen over and over as most have, that the RS tanks fail after a period of time. Looking at the construction and setup, to me there is a fatal flaw in the design from day one that is glaringly obvious and will...

I don't think I have ever seen a tank not go through an ugly stage especially in the first year of setup. It's natural and happens in every tank especially if you're starting out with dry rock and sand, and not using cycled media. Has anybody on here actually been lucky enough to skip the...

I’ve been out of the hobby for 12 years and I don’t know what made me do it but I am back. I bought a UNS40A. AIO diamond glass looks pretty dope. I made a beautiful rock formation which you can’t see in the clouds of the water as I just added water and my sand about an hour ago I had my heater...

I ordered a replacement tank for my current 150 gallon. I ordered it from glasscages. My question is what do you guys use to paint the black back ground I've always used black rustoleum oil based is this the best option?

Hi everyone, I've finally decided to upgrade my IM 50g lagoon AIO with a beautiful Cade Frag 1200 S2 I picked up a few months ago from a local reefer. I've had the IM for about 2 years and it has been a great starting tank that has taught me many great reefing lessons! Very exited for the...

Getting ready to add my first corals, was wondering what the best way to add them is. I don't have a QT tank so that is not an option, but I was wondering about dips or whatever your protocol is? The coral tanks from my LFS have easily visible aiptasia, sometimes on the frag itself. I want to be...

Hey needs some advice. So I have a 15 gallon that’s been running for over a year just got done battling a bad hair algae outbreak with the help of vibrant, and now everything is looking great I’ll post pics. But just bought a 20 gallon innovative marine now I’m in the process of cycling it. But...

Hello guys! Im fairly new to the saltwater hobby (I only have had a 15 gallon cube reef for around a month now) Me and my parents want to set up this 60 gallon cube tank we've had sitting around. So far all we have is sand, a stand, and the tank. I wont have many corals, just some fish. Maybe...

I set up new tank almost 2 months ago. Started with couple pieces of well established, Coraline covered live rock and bags of Caribsea live sand. Rodi water and seapora salt. Everything clear and looking great for weeks. Bought and added 80lbs of dead marco rock. Withing few days tank went so...

Hi everyone! Lately I have been mesmerized by what simplicity and patience has in this hobby.i have documented the start of this journey from the beginning until now. I have a 32 gal biocube that has been running for 5 years. I am just so proud of what it has become. I use a simple filter...

Pico tank, almost at 6 weeks with live rock and trying to figure out what order I should make my first purchases in? Lots of hair algae on the rocks and copepods too. What would you do? Thanks!

I’m using a biocube 32 and water from the lfs this time, as piecing together a system and trying to clean tap water were my biggest hurdles last time. So far so good, yes I was impatient when adding corals, but they are all extending polyps and putting on signs of growth. Blue leg hermits...

So I recently transferred my fish to a new tank 15 gallon to 20. Two clowns, a goby, and a fire shrimp. I transferred all the live rock, even biometric I had in the back chambers. New sand and switched waters came from Red Sea Coral Pro the Red Sea Salt. Left for work everything looked fine...

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...

Hello to everyone! I am new (again) to this hobby but looking forward to getting back into it. I had a 40g tank in the past (about 15 years ago) and I'm ready to get back into the hobby and I am looking at ordering the Biocube 32g. I am looking to see what are some reputable websites to use to...

I am starting a new tank, peninsula layout, 140x60x60 cm (55.2x23.6xi23.6 inches), 500L (133 gallons). I don't have ideas to the rockscape because: 1. I have a tank already with some rock but I'm not sure if I am gonna use it at all, probably just to cycle new possible rock (need some help and...

Hi Everyone - I'm new here and have been lurking for a while, but finally am experiencing something for which I could use some tailored advice. Would appreciate thoughts from anyone. Background: I ran a fishless cycle over the course of a month in late December / January. The tank completely...

I was gifted a large acrylic tank about 10 years ago and absolutely loved it. Everything was set up for me when I got it so didn’t have to do much other than change the water from time to time. Had to move to a small condo about 6 years ago and put the tank in storage. Just bought a home and...

Hey everyone, I am upgrading from a 30 gallon to a 60 gallon. The 30 gallon will be at my old apartment whereas the new tank will be in my new home so this will have to be done in a day. My plan is to transfer the existing 30 lbs of rock, 30 gallons of water, filter media, and the sand along...

Hi all, I’m very new to reefing and looking for some guidance with my cycle. I’d like to sanity-check whether things are progressing normally or if I’ve done something wrong. Tank & Setup Tank: Red Sea Reefer 300 G3 Rock: Dry rock Sand: Dry sand Test Kits Hanna Salinity Hanna Nitrate HR...

Getting back into the hobby after years out of it! Going to be picking up a Waterbox 20G AIO today with the stand . Looking for some recommendations on equipment to use or that’s recommended ! So far I believe I’m going to be using an AI Prime 16 Reef light and a Vortech MP10 wave maker . If...

This is everything I ordered for my nano tank setup, let me know what you think! All in all - it's about 2 grand, minus the livestock. Pretty crazy for just 15 gallons... but whatever. Hello Reef 15 gallon AIO w/ stand (~ $230) Norwesko 16 gallon utility tank (for water storage) ~$150 6...

I bought a new 125G recently that has two corner overflows. During the water test I noticed that water was flowing from the main portion of the tank into the overflow section, once there is more than an inch of water in the tank. I reached out to the manufacturer and they said it was a defect...
