Ruth Posted June 17, 2006 Report Share Posted June 17, 2006 Good thing, or bad thing? Coraline algae is a good thing (usually) but does not usually grow on a sandbed unless it is a faux sandbed glued down. The reason is that there are usually too many critters in there moving and shifting the sand. Make sure it really is coraline and not pretty purple cyano algea which is not a good thing.

dunl Posted June 17, 2006 Author Report Share Posted June 17, 2006 Thanks Ruth, I have had the lights on more lately, but I've also been dosing with reef builder. As I don't have a lot to stir the substrate, I was thinking the coralline might have spread. Guess I kill it with less light? Quote Link to comment Share on other sites More sharing options...

I would just vacume the sandbed a bit when you do a water change to stir things up a little. Like I said it doesn't usually spread on the sandbed - you might need a bit more flow in your tank. Coraline doesn't usually like really intense light although it will grow. I notice that it grows the best under VHO lights (at least in my tanks). Just make sure it isn't cyano - if it is vacume as much as you can out of there. Is it hard and crusty? - or slimey? Quote Link to comment Share on other sites More sharing options...
Murminator Posted June 19, 2006 Report Share Posted June 19, 2006 Sounds like it might be cyano Quote Link to comment Share on other sites More sharing options...
Ruth Posted June 20, 2006 Report Share Posted June 20, 2006 That is what I am thinking as well. Quote Link to comment Share on other sites More sharing options...
