innate1 Posted December 18, 2009 Share Posted December 18, 2009 I am still batteling the cursed cyano. All my levels are good but I can't kick the cyano. I was talking with Dave and he said he dosen't vacume the sand so that biology can run it's course. Sounds good to me. So do you all just syphone water out and then replace it? Sorry if this is too basic but I'm missing something. Thanks Quote Link to comment Share on other sites More sharing options...
Wryknow Posted December 18, 2009 Share Posted December 18, 2009 I will vacuum stuff of the bottom sometimes - a bit of nuisance algae would be an excellent example. I definitely try to avoid disturbing the sand bed too much though. I certainly don't vaccum the bottom like I do in our fresh water tank.

NonSequitur Posted December 18, 2009 Share Posted December 18, 2009 When I was fighting a bad cyano outbreak I would vacuum oarticilarly bad clumps of it off of the sand, but otherwise I leave detritus control to the cleanup crew. for water changes I either siphon from just below the surface of the display, or set the skimmer to skim extremely wet and collect water that way (takes a lot longer, but it seems to take out more gunk). 1 Quote Link to comment Share on other sites More sharing options...
+dapettit Posted December 18, 2009 Share Posted December 18, 2009 three days of darkness. I still think it's a flow issue. Quote Link to comment Share on other sites More sharing options...
+mcallahan Posted December 18, 2009 Share Posted December 18, 2009 I was battling it on my sand bed and I added 2 cucumbers and sucked off the stuff I could get to. The cyano is still around in spots, but its very minor and not growing. Quote Link to comment Share on other sites More sharing options...
+Daniel Posted December 19, 2009 Share Posted December 19, 2009 If you don't have a DSB, there's not that much of a problem with siphoning the sand... Quote Link to comment Share on other sites More sharing options...
offroadodge Posted December 19, 2009 Share Posted December 19, 2009 Hey INNATE1, FLOW FLOW FLOW>>>>Point a K2 at the area for a little while and it will go away. Then you will need to fig out away to increase the flow. I hv no cyano in display tank, but on the edges of my chaeto in sump there is some. FLOW is what its all about.

Derek Posted December 19, 2009 Share Posted December 19, 2009 When I get cyano I use Chemiclean when it gets really bad. If it just starts I angle my flow down a bit to keep the top of the sand bed well washed. Quote Link to comment Share on other sites More sharing options...

+dapettit Posted December 21, 2009 Share Posted December 21, 2009 I just found out last night that fuzzy limpets/chiton eat cyano. Who knew? Dave- Quote Link to comment Share on other sites More sharing options...
PeeperKeeper Posted December 21, 2009 Share Posted December 21, 2009 Thanks for making this post. I'm having what I've been assuming is a cyano problem too. Dark green, just on the sand, seems to vary with the amount of time the lights have been on. It's worst first thing in the morning and seems to get better after the lights have been on a while. Cyano, right? I think my problem might be overfeeding. I only have 5 fish in a 75G and we've been giving 2 frozen cubes OR a pretty large pinch of flake food (alternate days) except Saturdays and Sundays when the office is closed and there's no one to feed. However, I haven't noticed a difference in Monday mornings versus any other day in the amount of cyano. I'm going to cut the amount we feed in half anyway just to see if that helps. Maybe I'll direct my powerheads more at the bottom too. I have a very shallow sand bed, and it's been getting shallower as I've been peeling the mats off the surface, which takes some sand too.

+dapettit Posted December 21, 2009 Share Posted December 21, 2009 Sounds like overfeeding to me. Cut back to one cube and a smaller pinch. I feed all my tanks every other day (the tangs get Nori on the off days which every one eats ). Cyano is usuall red. Dave- Quote Link to comment Share on other sites More sharing options...
