Good morning, we're first. I'm Dave from Coralus and today it's Wisdom Wednesday and I just wanted to talk to you guys a little bit about refugiums and nutrient export and how refugiums are a great place to keep copepods because they thrive in there and it's just an awesome, awesome place to see life in your tank. Now I don't normally clean this so there is a ton of corlein algae on the glass so it's hard to see through there but just by looking around briefly you can see there's tons and tons of life just throughout this thing. So the other day I was cleaning out my refugium and and this is a nice sump and it's got it built in and one of my overflows goes down the side into this refugium so it gives it a constant pressure flowing from the right to the left. Now I have some screens in here to keep track of macaragogy from getting into the rest of the sump but that's one of the reasons why I also like this Cheito because it tends to stay in a ball and not make a mess everywhere but this thing was completely jam packed the other day hard to see in here it was jam packed with macaragogy so I took it out and just to give you guys an idea there's a little ball left in there now I put a little bit of ball in there but this is giving an idea how much really was in there I'll show you over here now I'm all about the refugiums and I have different macaragogy in each one and this you can feed to your tanks which is pretty good. I love it makes them pretty happy so yeah you would never believe all of this came out of that little itty-bitty sump over there and I was like you know what normally I throw it out but um because this kind is mixed it's not just the one Cheito it's got different macaragogy in there I tend to not like that I like all my macaragogy to be clean with just one kind so I won't sell the mixed Cheito but I decided to throw in this extra holding tank since I had room so kind of takes up on the bubbles and he does anything that comes down since I'm not using a filter sock but if you just even sit here for a couple minutes I mean you will see so much life there is just so much stuff swimming around down here and that is one of the reasons why I love the refugium it's not just the nutrient export but you can feed your tank with it if you're throwing um macaragogy that your tanks like um they devour this stuff I put a fox face in there and you want it crazy and you can see over here I threw a little bit of the other Cheito on top just to see what happens I noticed it grows differently in different speeds of flowing water in different lights and you know I also use the GFO so I wanted to see how the GFO and my phosphates everything worked out with the extra with the extra effugium Cheito eating up some of those phosphates so I just have a simple light on here this is a little LED that I got from Lose it's probably like a little 60 watt bulb replacement so and it's growing this stuff fine I'm not having any issues I hear a lot of people say they can't grow Cheito and it's a strange thing to me I don't understand it sometimes there's something in the water but when I was first cycling my system I couldn't get any of the Cheito to grow so I don't know like I said what happened there but anyway I do tend to pull out whatever is getting no light because that will die and release nutrients back into your tank and you don't want that so if it gets overcrowded you do need a trim back and you do need a prune and remove whatever you can so but you got all these beautiful corals on top of that eight foot long sump you know every ecosystem is different when you think about what I'm running and how I'm doing to look at that small skimmer I have anybody little skimmer in there compared to other people's skimmers on their little tanks and I'm running this massive refugium so it's so difficult to pinpoint every system a lot of people have tons of questions and hard to answer them all so we'll see how fast this chloropagros back and how fast it refills this whole thing but this like I said before was completely filled up to the brim which is macro out so each time I pull it out I try to clean it out and get a more pure strand of just a Cheito because I don't want to see how there's stuff in there so there you guys go feel free to leave any questions or comments below as always thanks for watching and happy reefing until next time
