Bryopsis Explosion!!!! - Aquarium Advice

gear-head · 11-02-2004, 08:28 PM

Tank is about 4 months old and has been through diatoms then [acronym:33f5b49870="Cyanobacteria"]cyano[/acronym:33f5b49870], now bryopsis. I think there is some hair algae mixed in, but it definitely is bryopsis mostly.

[acronym:33f5b49870="Phosphate"]PO4[/acronym:33f5b49870] is zero
Water is [acronym:33f5b49870="Reverse osmosis"]RO[/acronym:33f5b49870]/[acronym:33f5b49870="Deionization"]DI[/acronym:33f5b49870]
Salinity 35ppt
Ammonia, Nitrites are zero
Nitrates are about 5 in between bi-weekly water changes

I've been removing it by hand, but it grows back in a matter of days. I've cut feeding down to once per day and lights to about 6 hours.

Any suggestions? The lawnmover Blenny isn't touching the stuff.

Help

Some web research has yielded these suggestions:

Elysia: (Lettuce Nudibranch)

Royal (Tuxedo) Urchin (Mespilia globulus)

Thoughts?

I've heard that keeping a high [acronym:c9f94a2366="power head or Measure of the concentration of hydrogen ions, depending on context"]ph[/acronym:c9f94a2366] (8.6) via [acronym:c9f94a2366="Kalkwasser"]kalk[/acronym:c9f94a2366] dripping can help kill off Bryopsis. Also a Lettuce Nudibranch may help. Good Luck!

Any problems with a [acronym:3bcdedf7c6="power head or Measure of the concentration of hydrogen ions, depending on context"]PH[/acronym:3bcdedf7c6] that high (8.6)???

High pH is more intended for dinoflagellate (snot) algae and won't do anything to bryopsis. In fact not much will. The only real thing you can do is maually remove it as often as possible and do everything you can to limit nutrient. It's one of the hardest algae to eliminate. Many often never do and simpley achieve a quasy balance keeping it at bay.
