We’ve just bought our new home and I finally have the space for my first “big” tank. We’re on a concrete slab and I have room for up to an 84” tank! I’ve been doing some shopping, and ultimately I really like the Red Sea S-1000. I like it for its look, dimensions, and I like the sump layout as...

Hi all, Me and my family just got settled into our new home in the Nashville, TN area. I’ve been out of the hobby for a little while, but I finally have a designated wall in the house for a large tank I’ve always dreamed of! As we are unpacking and putting things away, the time for me to start...

Hello all, I will be having a mix between the 200 and 150 possibly. I got the 200 to see how it will be around the brace of my tank. Then I’ll decide on 2 more of the 200w or 2 of the 150s or what is needed (7x2x2 tank). on my nano tank I have a 65w Nicrew and am using the preset. What...

Like the title states. I can’t decide between a waterbox box reef lx 330.7 or the Cade 2100 s2. I’m leaning more towards waterbox because I currently own a 175.6 frag. Just wanted someone input or opinions. I have time to decide not planning on ordering until end of summer. Started buying the...

Picked up a 125 gallon tank decently priced with stand. Tank was up and running when I picked it up had to drain and rehome the fresh water fish that were in it. My concern is previous owner resealed the tank or so it looks. Top frame has cracks in the corners and the glass on the one side...

Hello Everyone, tl;dr - Mantis shrimp are not living for more than 6 months. Need advice. I am involved with the maintenance and upkeep of an aquarium system in a facility that deals with mantis shrimp (Odontodactylus scyllarus). The system had successfully kept and maintained mantis for 8 or...

So I recently got my hands on a brand new 150g for free, which I’m not setting up yet due to lack of space… but when I’m in a different living arrangement, I would love to start a reef tank. The thing is though that I want just a few larger fish instead of a bunch that are only a few inches. I...

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...
