large aquarium

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...

Hello, R2R! Since April, we have been weekly documenting our BIGGEST build yet-- the REEF LX 320.7! In this time, we have covered many topics: - Delivery + Uncrating - Set Up - Plumbing + Sumps - Equipment Planning - Electrical and Cable Management - Aquascaping ...and more! Join us for a...

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...

Selling CR818 calcium reactor, this reactor has never been used. But it has some water marks from sitting in my sump for a couple weeks. $550 + shipping (firm)

Ill be out of the hobby for a while. I will be upating prices as I learn them. Please, serious buyers only, i can't deliver pickup only. UPDATE!!! $3450 if you take everything at once. Old school Reefers know the value, wont last, and I wont hold without a deposit. Thank you for your time. 1x...

Who would like to own this? :p :p That's living coral on the rock work plus 2000 fish! 47ft deep x 33ft wide and just a measly 264,000 Gallons.

So I’m planning a large 360 gallon SPS tank. My question is, will this tank have enough coral growth to feed a Harlequin Filefish and make sure not too many corals are lost? Of course I’ll wait until the system is very mature.

If you could design a “new” series of tanks for the RedSea Reefer series, what would they look like and what features would they incorporate?

Hello all. I’ve never posted on here but enjoyed reading multiple threads over the past few months. We’ve just started renovation on an old home in Charleston SC. It had a perfect spot for me to install my in wall dream tank. I’m a custom cabinet guy so the tank will be sitting in my home office...

I hear all the time that small tanks are harder to maintain because of less water volume, any mess ups and your screwed. But with a large tank isn’t it harder to come back from a mess up because there’s soo much water. With a smaller tank you also don’t have to use as much of a product like for...

Starting a build thread on my 300 Gallon Planet Aquariums Peninsula Reef Tank. This this has a Total water volume of just over 400 Gallons (420 Gallons to be exact) including the sump and the refugium.

Hey gang, I had the good fortune of buying a custom built 300 gallon glass aquarium and custom built stand from my dentist a few months back. I've been telling him for a few years that I want to buy the aquarium because he didn't ever have any water in it (the previous dentist in the practice...

Hey everyone, To start off, I figured I'd say a little about myself and my fiance and our experiences in the hobby. I am lucky enough to have a partner who is as enthusiastic about the hobby as myself (at some points she can be even a bit too enthusiastic...) We have now been in the...

I know this would be my second 225 g aquarium purchase. I had started the other build but it’s been a stand still. (Time)(a lot is need for the tank) This is a shorter but wider and taller tank then my other one. I will be getting this done a lot quicker as it’s easier to turn around. It just...

Good morning all, So come April/May, we will be upgrading to a 425g tank - 120”x36”x24” and are going through the planning phase right now. I took advantage of Black Friday to buy a decent amount of the equipment and have planned most things out,however, the one aspect that I change my...
