Isn't brown Algae cause by pour water circulation? If so, shouldn't more
water movement fix this problem? ( before you flame me on this... I'm just asking, I'm not sure of the answer) |

Maybe I'll add another powerhead to rough things up a bit more ...
can't do much harm. Thanks! Julian Peter Pan wrote: Isn't brown Algae cause by pour water circulation? If so, shouldn't more water movement fix this problem? ( before you flame me on this... I'm just asking, I'm not sure of the answer) |

I don't know if it's the best way to do it, but I use a turkey baster
(occasionally) and blast the dead areas that start to cake up with waste and my filter usually takes care of the rest. "jjbunn" wrote in message oups.com...

I have now had the new regime for three or four days: lots of turbulent
water flow, 12 hour 250W MH lights, activated charcoal, Kent phosphate/silicate sponge, refurbished skimmer (collecting decent amounts of gunk). The problem with the algae persists. In fact it is worse, if anything. When the light first comes on it looks better, but within a couple of hours the tank is full of strands of brown filamentous algae. Is it possible that my MH bulb is causing the problem? It looks as bright and white as ever, but I'm clutching at straws now. What to do next? Thanks!

Here are some photos of the brown algae. These photos are not for the
faint of heart! http://static.flickr.com/80/260382277_5b5f86d466_o.jpg http://static.flickr.com/99/260382327_fc410b8aa0.jpg http://static.flickr.com/98/260382207_9e730ae038.jpg Julian jjbunn wrote: I have now had the new regime for three or four days: lots of turbulent water flow, 12 hour 250W MH lights, activated charcoal, Kent phosphate/silicate sponge, refurbished skimmer (collecting decent amounts of gunk).

They can be very bad since they can be toxic depending on the species. Normally they are a sign of very high nutrients in the water, not enough current, and possible bad lighting. The good thing is if it is dino's, you can just leave the tank dark for about 2 days (will not hurt your corals as long as they are semi healthy). After you turn the lights back on though it can come back pretty quickly. I would suggest tunning up your skimmer or upgrading it if possible, increasing water movement (the pictures show the algae floating straight up) and replacing light bulbs if they are old.

It's not hair algae. Looks like cyanobacteria. It will
look less, or even gone in the morning, and then show up after the lights have been on for a while. The light on light off thing is a good indicator of cyanobacteria. Cyanobacteria is a little more tricky than hair algae. Hair algae likes high nitrates, and cyanobacteria does not like high nitrates, and it likes to take free nitrogen, and fix it into nitrates. Cyanobacteria can wiggle like a worm. I've got some vidio on my camcorder of cyano under the microscope wiggling like worms.

And I recommend you get rid of the things that don't work
well in a reef tank, ie trigger fish. Wayne Sallee Wayne's Pets jjbunn wrote on 9/30/2006 9:17 PM: Hi Wayne, The turnover is pretty good: there are two powerheads plus the return from the skimmer plus the return from a hang on filter (in which I keep the charcoal and silicate/phosphate sponge). I have a lot of live rock in the tank, so there are certainly plenty of obstructions. I completely overhauled my CPR BakPak skimmer last night, and that seems to have improved the collection rate of skim. I've increased the lights to 12 hours on. I'm going to go with this setup for a couple of days to see what improvements there are (if any). Thanks again. Julian TheRock wrote: What about turn over of water ?

I will try again with a normal light cycle, but this has only exacerbated the problem when I've tried it recently. I have pulled clumps of the algae out, and continue to do so ... but it's often hard to get a hold of as it's so slippery. I've scrubbed the rocks with a toothbrush several times in the last week or so, but I have the impression this is just distributing the algae further! I have a Kent Phosphate and Silicate remover in ... I need to replace it now because it has been in a couple of days I'd love to add some snails ... I have a bunch of hermit crabs, but my Picasso Trigger just treats snails as a delicious snack :-) Julian |

Ha! No chance!
That Picasso Trigger is my pride and joy. In fact, the hawkfish is much more problematic, and I've tried many ways of getting rid of him.
