refugium flow

I have a typical 3 chamber sump in my 70g frag tank and it is about 30 gal. 1st is return from tank with skimmer and it skims some nasty stuff but happy it does. 2nd is fuge with a light and some macro algae of different varieties. 3rd is the return the chambers overflow one to the other as...

Hello everyone! I recently set up a tank (within the past couple months) and have been trying to determine what an ideal flow rate is for my refugium section. A little background... I have a 150 gallon display tank with a 13 gallon refugium, and about 15-18 gallons of additional water in the...

This is my newest tank, I still haven't put all of my live rock in I just moved it in my room on Sunday.. and I need to add more sand on top of that. There's not too much more work on it but there is still work needed. My two sharks love it so far the only 3 live rock I have in there at the...

Hello, I have a Fijicube 20 sump and have been using the refugium section for chaeto. This section measures 5.2" by 5.8" by 10" of water. I have been using this cheap grow light mounted to the sides of the refugium. It has been several months and the chaeto isn't really growing and the entire...

So I’m sure a bunch of you have seen @Bulk Reef Supply ’s videos on chaeto in a refugium and their graphs of nitrate and phosphate over time. Does anyone have anything similar for caulerpa? Or, anecdotal evidence for caulerpa to compare against chaeto in terms of phosphate and nitrate réduction...

Title says it all! Looking for a nice HOB refugium, preferably nothing too big, it's going on the back of a 45g. Also looking for an IceCap Gyre preferably the 1k, but also interested in the newer 2k. Let me know what you have!

Running an adv-100 sump and since the beginning have noticed pretty minimal flow through what's supposed to be the refugium chamber. Seems like it's getting worse and worse over time. I'm going to pull the foam between that and the return chamber to see if giving that a good rinse will help --...

Has anyone used or tried an intake refugium? Thinking about testing it out, just thought if anyone else had success with one?

Hi All. I will be setting up a display refugium off of a new tank - tank will be a 220 bare bottom into a sump. The refugium (24g/18in cube) is external to the sump and will be fed by a separate pump in the last chamber of the sump. It has an overflow that will return back to the first chamber...

Let me start off by saying how glad I am that R2R exists and how helpful all members have been during my initial startup process. The first 2 paragraphs are background and tank info so you may skip reading. I have decided to finally get my 40B up and running so I have been slowly gathering...

I have a 60 gallon aquarium with a corner overflow that falls into a 55 gallon sump. It goes through a felt filter sock and I have a protein skimmer in the large chamber. I have about 75 lbs of live rock in the display tank with a less than one inch deep sand bed.i have two suspended...

I grabbed the manual from the top of the first page and started reading through many of the posts in this thread. Now I have some confusion. I have an "established 75g tank" . 5 fish, crabs, snails, 2 corals (colony polyp and a green candy cane). About 130 lbs of live rock, heavy coraline...

Hi All-- I have a 100g cube, and in the stand below there's not a lot of space (yet one more reason I want a rectangular/long tank in the future). In the stand cabinet, there is a 15g sump and a chiller. In the sump, there is no more room for me to add anything into it. But there is a...
