I've been in a struggle with brown dusty (glass) & hairy brown ( live rock & corals) and rusty crusty on glass since last Christmas when I was gone for 14 days. Prior to that my parameters stayed stable with very little interference from me. I have the standard cleanup crew, several algae...

Same here. I know this is an old thread. My sump has black walls. Doesn't get any light except some red led from my algae scrubbers. My filter media is saturated with the stuff. It is below the skimmer intake, and doesn't appear in the DT. I do get a rust color on the glas that doesn't come off...

Okay, all my parameters are great. It opens up at night and looks fine. Every few weeks during the day it looks like this. Is this normal? Dinoflagellates maybe? No problems anywhere else in the tank. It has shade and great water flow.

My nitrates are always very low- I don't see any other GHA other than the remnants on chili. This is this morning at 8:00 am...

So - I did a check and believe 1. I was crazy to put the live green algae in for a clownfish and shrimp. Tangs yes - don't have them. 2. My phosphates were a little higher than normal, so I put in some phosban. 3. I cleaned up my chili with surgical tweezers and a soft brush. 4. I turned...

How do I get rid of the hair algae? It really isn't under the lights directly, there is a live rock ledge above it that shades it. I've had it in several different places in the tank and it seems happiest with the flow where it is. It has been growing new shoots. I put in some fresh green algae...

It gets nice and big at night about every other week for four or five days. It just started growing this "hair". Is the hair normal?

7 days- this is the most that have come out since I bought it . Each day more come out.

Trying to identify this so I can provide care for it. Thanks! :rolleyes:

Thanks - it probably is silicone. It is clear. Just nervous about ruining the whole thing! I have some good blades from a dreadnought my husband doesn't use! I'll go real slow....

I am replacing my red sea protein skimmer with a Tunze. There is a piece of glass that they epoxied in to hold their skimmer in place. It's about 1"x4" on the back glass wall of the sump. Any help on a way to remove it safely? It's in the way....

Does anyone have any opinions about algae turf scrubbers in the sump in lieu of a media rack to help control Cyanobacteria or algae outbreaks? I intend to put a Hog1x in the sump between my protein skimmer and outflow pump instead of a rack with a variety of filters, etc...

Here is a random one that is open.

Thanks, with cleaning rock and vacuuming detritis - I have it down to a dull roar, but I will order some! It is a zoanthid - that was a clump open, here is one closed up photo. I got a large rock of them from ***** at a ridiculously low price. I looked it up at the time and I remember it said...

Thanks to both. - I am trying to hold off on chemicals, I've heard of a few nasty ones that kill off the good bacteria song with the cyano. It probably is close to 40 since I've added in more in with corals on them. I really do t have room for more :-). My shave brush was multiplying. This...

Introduced some polyps on a live rock about 6 weeks ago (2nd pic). 40 gallon reef tank with 10 gallon sump, nitrates .05, nitrites 0, ammonia- 0, ph 7.8, salinity 1.025, temp constant 79/80F, 25 lbs of live rock, live aragonite substrate. I feed maybe once a week. Use R/O water. Thought this...

I have two nice shave brush? I think that's the same family? There is certainly macro algae in the tank & feedings... hmmm, good source of chloroplasts. Maybe I added some kind of trace element that is inhibiting something they need....

I have three peaceful lettuce nudibranches that don't harm my corals, anemones, or anything else.. In the past few weeks they have changed color from green to yellow. Are they trying to tell me something? I don't have anymore green algae, just red coraline. I do put up green and red algae...

I put mine back together with super glue. 75% of it is bright, the 3 smaller broken pieces are getting less colorful. I think the glue probably clogged the surface on the pieces enough to, em, um, kill those parts.
