Home from vacation . . . Could use a little advice.

What's your flow like in your tank? That can cause cyano. Also, old lighting can trigger it, etc. To remove, siphon as much out as possible, in increase the waterflow in that area, replace bulbs, lights out for 3 days or so, etc. etc. Lots of ways to prevent it but getting a good grip on what caused it is the main part.
