large aquarium

Whats up y'all! I have been working on my reef setup for the past few months after establishing my 300 gallon tank for a year. Everything seems pretty happy so far. We have upped the amount of nutrients such as amino acids and coral nutrition AB+. The Goni was closing through the afternoon until...

Hello everyone! I am looking to sell my entire set-up. Due to some personal reasons, I am taking a temporary break from the hobby. I will be back, but for now I need to focus my attention on other things at the moment. I know a system of this size will be hard for someone to purchase at...

Hello, I run a large 500 gallon system and have been having high nutrient problems. Right now I have them down to nitrates:30ppm and phosphate 0.2. I have no issues with algae blooms or anything like that and all coral/fish are happy and healthy but need to lower the levels. I installed a...

Hi y'all! I've been kicking around the idea of upgrading my system and going bigger. I was curious if anyone had some aquarium brands in mind they would absolutely avoid and who they would recommend for bigger tanks. I have a 75g now and was thinking I could use the same stand and equipment...

HELLO EVERYONE I've been working on this one for a while now and not sure what equipment I need to make it work. For right now it's going to be FOWLR but eventually I would like to add some corals when i get more experience. I've been in the hobby for 6yrs freshwater only. Now I want to try...

Bough two for 270G and holy smokes this thing should come with a warning; already sold one, this is the 2nd one - BRAND NEW IN BOX! I decided to go with fine oolite sand and this monster is just waaaaaay too powerful. This belongs on a tank 300 gallon plus or will be perfectly fine in a...

I need assistance with tips on cleaning the bottom glass perimeter of the tank. To complicate things, the tank has a 4in Eurobrace around the whole top and center. The algae is the tough green algae that grows on glass. I use a flipper to normally clean the glass, but this stuff is tough. I...

Pretty large tank, will be around 700 gallons. So should I cut the carpet under the stand and have the stand sit directly on the concrete? Or just leave the carpet in place?

Hello Reef2Reef community, Firstly, pardon any newbie mistakes in this post; I'm still getting acquainted with this platform. A bit of background: About 5 years ago, I was the proud owner of a small reef tank. However, circumstances led me to sell it. I also have a history with freshwater...

Recently, I transitioned a fairly healthy 200g SPS dominant system to a new 340g system. The previous system was stable. Before I broke it down the 200g system, I had started to see some occasional coral mortalities in my frag tank. The new system is 4 months old. Over the 3-4 four weeks...

*Please not that this is a package deal* I’m helping a friend liquidate his aquarium collection before he moves out of country. He’s very busy with the move and prefers selling it all as one if anyone is interested in parsing it out themselves. A lot of new equipment that hasn’t been used as...

Decided it was time I upgraded my 125 petsmart build, to something a bit more professional. After weeks of research on all major brands (Waterbox, redsea, Prostar, SCA etc) I finally settled on the innovative marine 200, I really loved the Eurobracing, aluminum stand, sump, and lets be honest...

I suppose "large" depends on what you're use to. I'm just wondering if anyone has specific examples of or experience with tanks dedicated to tiny creatures? Rather than being stocked around minimum sizes, or a mixture of large and small. The closest I've seen are clownfish harems. Half a dozen...

After 3 years and 1000s of hours of youtube researching (I think I have watched every BRS video available) and learning coral reef biology with my mixed reef 65 gallon tank I have started my next reef project. I feel like Ryan and Randy are family!! I have purchased the Waterbox Reef XL 270.6...

Just started scaping for my reefer 900 and this is my 2nd attempt lolFirst attempt was ok, I did a horrible job of applying the mortar and when I tried to lift it some rocks did detach I've seen most people do it out of the tank so that's what I did, just wondering once I'm done how would I get...

This was a tank that I had planned for a long time now but the setup was delayed by a long time :(finally got to actually setting it up recently! :) The tank arrived at my house pre-winter 2020 lol Couldn't figure out how to lift it at first and was busy so I kinda just forgot about it :( but...

I finally got the OK to upgrade from a 40B tank to my dream 225G 72x30x24 tank. I've had my 40B for 2.5 years now and since I'm still hooked to this hobby, I'm going to take it to the next level. Please take a look at my proposed build and make suggestions. It will be a mixed tank with SPS, LPS...

So it’s happened, I purchased and picked up a 600g aquarium. The dimensions of it are 10’x4’x2’(LxWxH). I currently have a 225 up and running that will break down once I get the 600 going. I’ll post picks of this thing. By the way the pictures don’t do it justice. The location of this tank will...

I’m looking for a large tank 72x24x24+ To continue my build. I had a tank, but last night while scraping the old paint off to repaint it I found a crack!

I purchased a Crystal Dynamics 225 gal peninsula (72” x 30” w x 24” h) a little while ago, and the tank is finished and ready to be delivered. I’ve been super excited to get it delivered and set up, but as of just a few days ago it looks like I may be moving in the next year or two. As badly as...
