Does anyone have any idea why one of my zoanthids is starting to bleach? My parameters are all good(my nitrate goes back and forth between 1-5 and pH 7.8-8.0) Maxspect razor r420r LED lights. Also in the pictures you can see that its only visible when the polyps are closed but it doesn't open up...

Hi everyone, I was hoping someone may be able to help me. I am trying to understand what this type of algae is in my tank (please see photos). My tank is around 3 year old now but I have always tended to have difficulties with algae problems, in particular green hair algae. However, having upped...

Hello fellow reefers, I am stumped. I have recently had a sudden decrease in tank health and was wondering if anyone had an answer to my problem. I had made a water change (10-15%) which seems to have done way more harm than good. I have lost almost all of my zoanthids and irritated my...

I am experiencing problems of high ph in my new reef tank. I have kept reef aquariums for 5 years now and this is a new set up. It has now been running for 2 months. First here are my tank specs 800 litre display tank 300 litre sump 2 jeboa power heads (can't remember the exact spec but I run...

Hello everyone, Id like to get some input about my trouble with tangs. I have had my reef up for about 4 months now and I currently am housing 2 clowns, a cherub angel, a lemonpeel angel, and a lubbock's fairy wrasse. I wanted to complete my stock with a smaller hardier tang and later on maybe...

My tank (29g biocube) has been established for almost 7 weeks now. It cycled in about 2.5 weeks and I haven't had any issues with algae since then until about 10 days ago. My glass has to be cleaned daily because it gets caked in green algae and my sand bed looks awful as its covered in brown...

Is it safe for a Sea Urchin and Bubble Tip Anemone to be touching? :(

So to make this quick and hopefully simple, I hooked up this skimmer about a week ago and everytime I plug it in it fills up and starts overflowing the collection cup. The way to control the flow is also very confusing to me and the instructions it came with were of course not useful but no...

I'm hoping someone can help me. I have started the last few days having problems with some of my corals. One in particular has not opened for a week and I have no idea why. I also have a massive problem with algae which won't seem to go away. I need to clean the glass every day. I have some...

OK so I hate to be one of those guys posting one of those "All my parameters are fine but my tank is doing horrible, tell me what the problem is" threads but I'm starting to get worried. The corals in my 150gal are not doing good. My green apple monti cap which was doing great is only green...

Found this starfish on my live rock a few days ago, he's usually a green with purple stripes, but it looks like his one leg has turned a whiteish colour. I hope he's not dying. Does anyone know what kind if starfish he is? He's quite small but loves to travel. Is he reef safe? I don't have much...

Hi everyone, Im new all of this and im having a bit of trouble atm with my anemones and corals.. when i first got my (10gal) nano tank everything went great! :) all the coral seemed very happy the fish were happy and the anemones were hosting my clowns very well. Now that i have had my...

strangely enough, after accidentally cutting off a few tentacles of a totally different torch, one of the purple heads I had on the other side of the tank totally melted away in one morning. in addition to this, the last 2 mornings I have found a juvenile trochus snail on the floor. each...

I have been trying to catch a crab using the water bottle trap. All I have caught are hermits, and my orange serpent starfish. When I took the starfish out, he just went limp. I laid him down on the substrate and my peppermint stated to pick at him. So I put him in the sump for now. Any ideas...

So when I first bought my green bta it was all green and bubbly and then after a few weeks it started to get brown and now there are no bubbles at all. I have a clarki clown hosting it atm. Anyone know what would cause this? Your fellow reefer, Nathan

In early December I began to cycle my first 30 gallon saltwater aquarium. The tank has been cycled I have 2 Ocellaris clown fish, 1 damsel, and a coral beauty angel fish. I started to get this weird red hair all over the tank on the sides the front on my powerhead and my heater. I checked my...

Reading through "Reefkeeping made easy" look for suggestions to fix my problems So I have glanced at reefkeeping made easy in the past and with my constant battle with algae after upgrading my tank, losing 3 fish, and my eligance coral not doing so well I started reading at page 1 and am now...

I just started filling my tank and I got called to work. I've never had to leave home longer than a day. I will be gone for 3 weeks and i was wondering if it would be alright to run my tank without any rock? I already have the sand in and the rock supposed to be here In 3 days but I cancelled...
