Refugium

I've done some research and it sounds like something we'd like to do but I have some questions and since there are a lot of helpful people on here with a lot of experience here it goes...

We have a 29 gallon which is slowly turning into a reef, we only have 2 corals and 1 feather so far. We have 2 blennies that love copepods but will eat other stuff like brine and have found they like zooplankton too when we feed the pipe organ.

Right now on the back of the tank is a CPR2R bak pak skimmer, I know some don't do sumps but we are constantly adding water to the thing, we had that problem with the tank when we did fresh water too, not the same tank but same size. Hence the thought of maybe going with a sump and putting the skimmer down in it then it would free up the back.

My question is with the refugium would it cause extra weight by hanging it on the back of the tank wouldn't it cause more weight on the back of the glass therefore putting more stress on it?

My other question, could we do a Sump/refugium all in one thing and still be able to have the benefit of the copepods.

And my biggest question, when you have a refugium and you put macro algae in it to grow I take it that when the water goes into the tank it will seed the tank with the macro algae?

Oh boy this brings up another question... Macro Algae, I realize that it combats some algae like the bubble algae I have now, but from what I've read it seems like when you get the Macro Algae it seems to take over and when you try to control it you have to becareful of how you dispose of it, would that be the same of the water that you change, the old water shouldn't be put down the drain or down the storm drain. We don't have a fish that will eat the Macro Algae if we purchase some, we have 2 blennies and 2 percs and 1 green brittle or sea serpent that won't eat anything bigger than brine shrimp. We've tried a false lemon peel and that didn't work out and would hate to buy anymore fish, everyone is healthy and gets along.

Thanks for taking the time to read the novel and for the help in advance.

If you mean green brittle star, then it can and will eat things larger than brine shrimp. Your blennie comes to mind.

Where else can you dump old SW? Sometimes I throw the harvested macro in the garbage. If you get grape caulerpa started, it is one of the easiest to harvest and it grows fast, taking nutrients with it.

I'll try to answer the questions that I can. The sump is a good idea and you'll like it very much I think. As far as adding a HOB refugium, I have one on my 10g tank. It goes all the way across the tank and holds about 4 gal of water. No problems with the back glass...it'll hold it. Be sure you get one that is small enough to leave room for the overflow box that will have to hang on the back of the tank.
If you want to create a sump/refuge, remember that the refuge needs a relatively slow flow compared to the sump. What you could do is have a separate compartment in the sump with a small PH feeding it. Then let the water from there overflow back into the sump in the general area of the return pump. The only problem I can see for you is room. I think it's going to be really tight to get all that under a 29 gal tank. CPR makes some neat HOB fuges or you could build one.
I really don't know enough about the macro algae to make any comments about it. I haven't tried it yet...I've heard arguments for and against it...haven't decided whether I want to try it or not.

Thanks to you both, not only for your replies but for reading the novel and getting back so quickly. First to Anemoneman I think it's a green serpent, we've tried feeding him krill that was the size of a dime, didn't touch it, had to take it out the next morning, tried chopping it up and he ate some but really seems to love brine and the leftover flake that has made it to the bottom when we forget to turn the PH's off. As far as nutrients, don't I want those in the tank? I'm just afraid of putting something in there that is going to go bezerk.

Logan, thanks for the help on the refugium, we don't really have a lot of room on the back so we may go the sump routine, I checked out your DIY projects and that's what got me even more interested. Right now we have our 29 gallon kittycornered, it's sitting on a pine stand that we bought at Petco with a hood, we just had (a couple months ago) had a pergo type flooring put in and that's what the stand is on, seems to be doing well, my concern is the sump, didn't want one at first because one I didn't want smell in the house, but now after doing this for a while I realize if you keep it maintained there won't be a smell. I have seen that some sumps have like covers, but I realize that if we make it a sump/refugium that the refugium part shouldn't have a cover over it. We'll have to figure out what we are going to do, it's so hard to decide, I find that is the hardest part of this. Trying to decide what is best when everyone has so many different ways of doing it.

Thanks again to both of you for your help!

How big is the Green Brittle?

Nutrients that the algae uptake are what you DON"T want in your tank, things like ammonia, nitrate, phosphate, etc. When you remove handfuls af alage, you are removing hanfuls of these substances. It is a very efficient form of filtration.

Don't put a cover on your sump, fuge, or tank. It won't smell unless something's wrong.

I agree 100%. The primary function of the sump is to give you a place to put your equipment and provide circulation. It also is a great place to dose additives, add make up water, and do water changes. You know, I'm sure, that bioballs or other bio media is not needed or wanted in the sump. This is where it differs from a wet/dry. Some folks use a sponge prefilter in the overflow box or a sponge or bag in the sump to trap large particles. I don't...the scavengers in my tank do a good job on that stuff. You'll also need to be sure that the sump is of sufficient capacity to hold the water that will run into it in the event of a pump/power failure. I think you'll have room on the back of the tank, once the skimmer is moved to the sump, for a HOB fuge. The tank will have to sit far enough away from the wall to provide clearance for the overflow...the fuge should not require any more room than this.

The HOB refugium do they come with a light or does it rely on the light provided by the tank? As far as the sump goes I'll leave that to my husband to read what you just posted, I'm not one for the plumbing end of things.

The Serpent Star which is what I believe it is, here's a pic of it, he's pretty big in my opinion he's missing one of his arms we bought him that way he didn't lose it when they caught him, it's in the process of growing back which is really cool looking. Here's a pic of him, hopefully IE won't give me a "Do you want to send this error in" thing again tried posting it before :/

The HOB fuges don't come with a light. I know lots of folks recommend reverse lighting the fuge to help stabilize pH. I haven't tried it yet...my fuge is full of pods and worms...no light on it yet. You can get a 13w PC kit from AH Supply for under $20 though...should be plenty of light for a HOB fuge. I suspect that one of the screw in 6500k PC's from Home Depot would work as well.
I get the IE error once in a while too...frustrating isn't it ?

That's a green brittle star alright. I had one that lost two arms in a tank crash (not mine). They grew back but were a little thinner than the others. They are definitly carnivores. I never saw it eat my fish, they just came up missing. Shrimp too. I saw it eat flakes, brine shrimp, and formula one. Ate a lot of sand fauna too. Amphipod population went up after I get rid ot it. Haven't had any disappearing fish either. If you can't figure out where a missing fish went, you have been warned. Every tank's different though. Good luck.

Aww I didn't want to know that, I guess that would explain why we had a hole dug in the side of the sand this morning, wonder who he was after :/ Now the problem of trying to get someone to take him
