I found a 20# base rock on cragslist for $60 dollars, after talking with the seller I found out that the tank it used to be in has been treated with copper about six years ago (or so they say). My question is, is there a wary to test it for residual copper? and, is it worth thinking about for...

I am getting my quarantine tank finished today, and wanted to see if I have the right idea. The fish that I am getting is a coral beauty. I have a ten gallon tank, heater, some pvc pipe cutouts for hiding places and a biowheel filter that has ben running on my display for a few months now...

I have a 29 gallon reef tank and want a school of blue cromis. How many can I put in the tank? They will be the only fish w/cuc and corals. The lfs said eight but that sounds like way too many. Thanks for your help.

I have a 29 gallon bowfront and am upgrading from crappy powerheads to two of these koralias. What size should I get? I was leaning towards the 450 gph. But I want as much flow as possible without any problems.

I just pulled this bristle worm out of my 29 gallon. Slowly but surely their population is dwindling.

Okay I am looking at my aquarium and there are thousands of what looked like micro bubbles on the glass. Upon closer inspection they are alive, and moving around, they look like little lice or something. The bugs are much too small for a picture (about .5mm or less) any idea what they are? Pods...

I think this is cyano on the substrate. Does anyone know why it is there? My readings are: Ammonia 0 Nitrite 0 Nitrate 4-5 pH 8.4 I have been feeding sparingly twice a week. Lights are on about 10-11 hours a day. My camera is really faded, so there is more than it looks like...

I was watching a movie about twenty minutes ago, and I glanced at my tank. To my horror I saw one of my anemones stuck in the power head. I quickly unplugged the ph and it let go of the anemone. None of the anemone was pulled into the ph, but he does not look so good, has anyone seen them pull...

I was reading an article about hydroids today, and had to look over my tank to see if I could find anything, Lol. I think this might be one. Does anyone have any thoughts? Also I found a few sponges I think? One if then is about a centimeter tall and looks like a tree.the other is on the...

Hi...I'm TurboSnail's girlfriend, I've got a 10 gal. freshwater aquarium. I recently bought a test kit and noticed I have two different pH tests. One is pH and the other is High Range pH. The instruction book that came with the test kit says I'm wanting a 7.0 reading. My question is do I need to...

Around two weeks ago I mixed up ten gallons of water to do a pwc. I ended up not needing to do one, so I put power heads into the buckets and snapped the lids on. Today I was planing on doing a pwc and when I opened the buckets there is a bunch of white things in it. it kind of looks like a snow...

My tank was purchased cycled w/fish, I have traded most of them off except the clown. The tank is a 29 gallon w/live rock. A few days ago I changed the substrate from crushed coral to sand, I did this to get rid if the under gravel filter. I now use a bio wheel 200. Last night I tested the...

I recently purchased my first reef tank. I have read though the stickys and could not identify these. First is a vivid green disc, it has a mouth like an anemone and closes up at night, the picture does the color little justice. Second a small anemone I think, it is clear and about the size of a...

I was just given a few little soft corals, on their base there is a small amount of what looks like string algae. The tank that they came from uses tap water I use RO water. Is there a way to remove the algae? Should I not put them in my tank? I don't have a quarantine tank suitable for...

I've been reading through this forum and have had successful freshwater tanks in the past but have always wanted saltwater. We found a 29 gal. Reef tank in our area on Craigslist. I know bigger is easier to maintain but we live in a small appartment and this is the largest I can support. It came...

Hello! I've just bought a used 29 gal. reef tank. Ran into a few snags already and would like some input.... We live in a small town with only one lfs and petco:(. Most of what I know about Saltwater is from reading on this forum so thought it was time to sign up. I'm going to put up another...
