sand

[alexg_28]

hi to all bro,

I got a question about my sand. It's very different from the one inside my sump tank. I mean the colour of it had changed to red/brown on the surface, created a lot bubble on the sand itself. The one inside the sump look the same as day one. So is this okey or is the bubble poison gas? Tks

I think its cyano. Common for new tank setup. Hope the weblink helps.

try to leave your light off for 3 days and it will clear off by itself .

beware if you have sps. try to search on this on reefcentral.com

i did try this myself and it does work for me

Hrmz, i think its better to get to the root of the problem. Do a search and you find some of the root causes of cyano. Leaving the lights off might cure the problem but its proberbly only be temporary. Good luck~

I used to have the same problem but my condition improved after I added a Turbelle nanostream 6025 for better circulation and a FR Reactors to reduce PO4 in the water.

Tomorrow i intend to change 10% water n monitor this another week.
