not hair algae????

[ilikepie777]

Ok so it turns out the so called hair algae i found in my tank was actually Bryopsis does this make things worse or better

[hollister]

Bryopsis is long hair algea. Sign of high phosphate and or nitrate. Could be low flow or poor circulation , overfeeding , water source , any or all.

To me Bryopsis is more difficult to eliminate since merely reducing nitrates and phosphates will not eradicate it. Manually remove as much as possible and then use Kent TecM Magnesium (for some reason Tec M works best) to raise your magnesium levels to 1600ppm and keep it there for a couple of weeks.

Just finished battle against the byopsis:Buy Kent's tech m, then buy 3-5 lettuce nudibranches. Take approx 2 weeks n celebrate.

IMO it's much worse. I had it for a while and tried manually removing but couldn't get it all, tried a nudi but it didn't like it and eventually starved to death, and I'm not a big fan of chemical solutions in a confined space. Turns out my problem was really just not having a good enough cleaning crew. To quote my friend "if you have a good cleanup crew, nothing green will survive in your tank" .. referring to algae of course, not corals.

Here is the post he left me when I had the same problem:
=============================================
tuxedo urchins,tiny hermits,mythrax,large turbos in the right dense population will clean anything green from the rock if you stop feeding the nutrients that started the bloom.

The reason this does not grow out of control in the wild is because of no magic or elevated mineral or heavy metal ratio but the ratio of herbivores and the low level of nutrients wipe it out.There is always a safe biological control for all algae and if the hobbyist is patient and diligent with nutrient export,it is not a lost cause and quite manageable.Yellow tangs are also the cows of the reef IMO and any reef large enough to keep them alive should have one or more.They all work together on different size and length algae to eradicate.I have used this method many times with 100% success.The patience and diligence of the hobbyists will dictate how long it takes.Stock heavy with assorted cleaners mentioned above and your rock will be clean (eventually) GL

BTW I had already owned a tang at the time, but I did stock up on small hermits, small snails, a few turbos, an urchin, mythrax (although I haven't seen one in months) and in a month or so every ounce of bryopsis was gone...to be honest I don't even remember when it went away, I just one day looked in and said..."hey...all the bryopsis is gone..I forgot all about that"

so can i use the magnesium stuff with inverts around?
