However, if you had a whole lot of light but no CO2 or ferts, the plants would have a lot of trouble using the additional light, and you'd be more or less guaranteed a horrific algae outbreak. People do say that Java Fern gets "burned" in high light - I've never seen this happen, and I've kept it under 320 watts of VHO or 13 wpg on a small tank. C'mon - the natural light for this plant is the sun, we're never going to match that. -Molly Visit shelldwellers.com!

And I fully second that horrific algae outbreak...or worse cynobacteria !. ^_^

It's such a nitrate and phosphate sucker I wouldn't be surprised to find that the cause of the browning is running out of nutrients to go with the light, rather than being bombarded by too much light. -Molly Visit shelldwellers.com!

I asked a local grower and he suggested too much light. I dismissed this as I only have 2.5 wpg. But sure enough any moss in direct light died off, the shaded moss still going strong. Classic example I had one rock covered in moss, half the rock was under direct light, the other half completely shaded by a Java Fern and yup the exposed half of the rock is now completely bare, the shaded half still going strong Some days you're the pigeon and some days you're the statue. Remember that age and treachery will always triumph over youth and ability.

littlemousling Conchiform Posts: 5230 Registered: 23-Aug-2003	I've been doing well with Java moss in high light, except when it gets choked out by bladderwort. :hrug:: Different tanks, always tough to compare. -Molly Visit shelldwellers.com!
