jemram Posted December 6, 2006 Share Posted December 6, 2006 Well I got started on my 'FilterFuge' today, which consists of an Eheim 2224 external filter and a 10W light. This is to run on my 18 inch cube which runs a closed loop, so a conventional refugium is out of the question. See my thread HERE to see my tank. The sole purpose of this to to grow cheato to reduce nitrates and phosphates. I need to say a BIG thanks to 'Fish' for the idea. Here's the underside of the pump housing of the 2224: And the tiny 10W bulb: This looked the best place to drill the hole: And with a good splurge of silicone: And my fingers afterwards! I'm now waiting for the silicone to dry and will update with more pictures soon. Link to comment
jemram Posted December 6, 2006 Author Share Posted December 6, 2006 Well it's on and running: Link to comment
Reefgeek Posted December 6, 2006 Share Posted December 6, 2006 I have been seriously considering doing this myself using a magnum filter. Since it is completely clear I can light it from the outside. Great job and thanks for posting this! Link to comment
jemram Posted December 6, 2006 Author Share Posted December 6, 2006 I wasnt happy with the mess of silicone so I've filled the hand hold with silicone. I've also looped the lead for the light into the hand hold so it's more resistant to getting snagged on something. Link to comment
aquakevem Posted December 6, 2006 Share Posted December 6, 2006 interesting, is it going in your stand? Link to comment
jemram Posted December 6, 2006 Author Share Posted December 6, 2006 interesting, is it going in your stand? Yes it will do. I'm just going to have it sitting outside the cabinet over night just to check for any leaks. Link to comment
Reefgeek Posted December 8, 2006 Share Posted December 8, 2006 Where did you get that little light, or is it DIY? Link to comment
jemram Posted December 8, 2006 Author Share Posted December 8, 2006 Where did you get that little light, or is it DIY? I got it from HERE. I'm not sure if it's avalible in the US though. Link to comment
Mr. Fosi Posted December 8, 2006 Share Posted December 8, 2006 Do you have any info on the specrtal output/color temp of the lamp (didn't see any on the site)? Link to comment
Izzue Posted December 8, 2006 Share Posted December 8, 2006 Nice Job Jemram... YOu gonna mod a heater also??? Izzue Link to comment
jemram Posted December 8, 2006 Author Share Posted December 8, 2006 Do you have any info on the specrtal output/color temp of the lamp (didn't see any on the site)? I have no idea. It's a halogen bulb and has a white to yellow light. At a rough guess something arounf 6500K, but I really have no idea. Nice Job Jemram...YOu gonna mod a heater also??? Izzue I have no need as I'm running an external inline heater. Link to comment
jemram Posted December 8, 2006 Author Share Posted December 8, 2006 Well I know you all think I'm mad, but I added the cheato today. First here's the unmodded Eheim filter basket. There are two of these in my filter and there is a 2" empty space below them. To allow more room for the cheato to grow I cut the bottom grate out of the bottom basket: Here's the bottom basket (not much of a basket now!) installed: And with cheato added: And with the top basked installed. Note the hole I've cut to poke the light through into the cheato chamber: And lastly, all set up and running: Now I just wait and see how well it grows and monitor my nitrate and phosphate:D Link to comment
Reefgeek Posted December 14, 2006 Share Posted December 14, 2006 Here is a 2x10w version of the light he used that is available in the US. http://shop.vendio.com/Evan2002/item/567566169/?s=1166007601 Link to comment
Mr. Fosi Posted December 14, 2006 Share Posted December 14, 2006 I'd love to get a hold of those run them by a photodetector... Link to comment
metasyntax Posted December 15, 2006 Share Posted December 15, 2006 Halogen bulbs are typically 2800K - 3400K, at least for purposes of color correcting photos. I've never heard of a halogen with a higher color temperature (doesn't mean the don't exist though). You can grow plants with them... they're just not very efficient at it. See below for a halogen spectrum graph: http://www.mtholyoke.edu/~mpeterso/classes...or/awgachor.htm Link to comment
polyppetey Posted December 15, 2006 Share Posted December 15, 2006 have you thought about using a piece of large arcylic tubing to lengthen the center section to increase capacity?? Link to comment
Scott817 Posted December 21, 2006 Share Posted December 21, 2006 Is there a way to slow the flow down? I wonder how benficial it will actually be pumping though the filter? Will the cheato have time to actual do its job? Link to comment
patrickross Posted December 21, 2006 Share Posted December 21, 2006 Why not just use a ten or even a five gallon tank as a refugium? It wouldnt be hard/expensive to silicone in two baffles. Link to comment
jimmy595 Posted December 21, 2006 Share Posted December 21, 2006 I think chaeto actually works better in high flow. I think the idea of this fuge is so that the tank can have a clean look, with no equipment, or even baffles visible. Link to comment
Scott817 Posted December 21, 2006 Share Posted December 21, 2006 I have been thinking about this type of fuge since seeing Chad's version for some time myself for a Nano cube without having to drill the tank itself and just notching the hood out. Link to comment
Reefgeek Posted December 29, 2006 Share Posted December 29, 2006 Okay, its been a few weeks, how is it going? Any noticable drop in your nitrates or phosphates? How is the cheato growing? Link to comment
jemram Posted December 29, 2006 Author Share Posted December 29, 2006 Okay, its been a few weeks, how is it going? Any noticable drop in your nitrates or phosphates? How is the cheato growing? The cheato is about double the size it was when it first went in. Also my nitrates were 20ppm, they are now 5ppm, so it's clearly working. And my SPS has gone from this: To this: Link to comment
Reefgeek Posted December 30, 2006 Share Posted December 30, 2006 damnit, okay looks like I'm next to make one Link to comment
Jim_i Posted December 31, 2006 Share Posted December 31, 2006 You're not the only one DragonFish! I'm curious what other types of small lighting are available? Wonder if a 6500k LED would be better? I guess I'll start searching... Link to comment
