Hi! Been a while since I've been on here due to a move which ultimately left me no choice but to break down my tank and give my fish etc to a friend. Not such a bad thing though as my tank was not ideal for saltwater so I get to start all over again and do it right! An absolute necessity...

I bought some seachem strontium supplement from mf LFS today after over a year of my LPS corals not growing/expanding their skeletel base. I thought it couldnt hurt to try. The corals have been rather happy this past few months opening up wonderfully under the new LED lighting I got. After...

Is this slug/snail thing safe for my reef tank??

This dark purple algae is all over one of my LFS's live rock tank. It's not good is it? Am I safe to buy fish from them??

Hi again, I have recently upgraded my lights to a single unit 240W Led system. It puts out next to no heat and has a 3 fan heatsink on top of that. My old lights put out much more heat than these do. My old lights where part of the stock standard hood that the tank came with and with the...

I just bought a bag on Coralife salt from one of my LFS and the salt was hard as a rock. When I picked the bag up it felt like a bag of solid cement. He said if I just break it would be ok once it was smashed up again. Is this the case? Thankyou

Ok Guys, So I took your advice and upgrated my 39 Gallon/ 2foot wide tank with an LED setup. This replaced the stock standard hood and so far it looks great. Both the blue and white leds have a dimmer dial and on the lowest setting it is already WAY brighter than its predecessors. A...

Hi. I have a 39 Gallon tank that I bought with a stock standard hood with lights. I'm thinking of doing away with this hood and replacing with a better lighting unit. Will 2x25W T5HO be enough to keep a frogspawn and hammer coral happy? These two corals are the only corals that arent doing...

Hi guys! I have a few wierd things in my tank and would like to know what they are: Image 1 - The Green Anemone Thing. I have had it for nearly a year now and only in the past week have 2 more popped up next to it. Retracts when touched in the same way the Paly's next to it do. I've asked...

Can someone, or multiple people confirm that these 2 statements are true. 'ICH is something that is introduced to a marine tank. It's NOT something that all fish have and develop further when stressed' 'If there are no fish present in a marine tank that previously had ICH, the desease will...

Hi! I have a pair of tru percs that I've had for about 6 months now. They are both fighting fit and where paired when I got them. I recently bought a nice big leather coral which the female has started hosting in the past few days! (score!). But since then, they have started behaving odd...

So we have had that much rain here (Qld Australia) that the river mouth that I normally get my water from had nothing but fresh water in it. So I was forced to get the salt and make my own. I live in a small unit and there is not room for storing the 25ltr drums inside. My question is, Can...

So it turns out there are a few black and yellow feather stars hanging off our bots ramp where I get my water. I have read they are hard to care for but willing to give it a go. My question is, if they do struggle, will the wipe out my tank in the same way a dying anemone can?? Cheers Also like...

I have a pair of clowns in a 130L Tank with a firehawk and a royal dotty back. All 4 fish have been getting along great. (though the female does chase the male around for a small while when the male starts flirting with the other fish) Today I went home and found the male sulking behind a...

I have a couple of these polyps things that i know are ok (first pic) and i've been praying that they spread. ive been feeding them heaps for a few months and nothing. Now I notice these things other things (that have been in my tank for months) get bigger and start growing longer tenticles...

I have just bought a flame hawkfish (which I would like to add is totally awsome) He likes to hang around my forgspawn coral and will occasionlly brush past it. Last night he was sleep underneath it and when I got to close to the tank he even scooted on top of it for a second before running off...

I have this plant thing that has been growing for about 2 months. probalby doubled in size since then. It branches out and is flat-ish. It kinda soft and moves a little in the water current. Good? Bad? Run for the hills?

Looked everywhere and can't find an ID on this. comes out at night. is quick to retract when the lights go on but i did manage to get a very good shot of it. it always comes from the hole on the right. the two flat things on the left is its head(s).. lol. it can stetch out to about 15cm at least.

Bought some new rock a few days ago and noticed these small white peble looking things (tiny) kinda swaying out of a crater in the rock. A few days later they where in a different crater. Then last night at about 11 I turn the lights on and find out its THIS thing. Its a worm or really small...

Hi again, I have a pre-manufactured tank (platic hood with built in lighting case, filter etc) that accomodates for compact flourescent lamps. The case is an Aqua-one 620T - roughly 38 Gallons. Slap me on the wrist if you must! I've done alot of reading about lighting for the possibilty of...

I have a 40 Gallon tank with a couple of clowns and a small wrasse plus an anemone i got last week. going away for 3 days and just want to know if its best to leave the light off or leave it running the whole time. cheers

Hi, Its now been a week since i bought my mated pair of True Percs and I am yet to see them eat anything at all. I'm starting to get super worried and sick in the stomach just thinking about it. The only other two fish i have are a small wrasse and a blue damsel fish that's totally...

Hi all :) New here, so I thought I'd ask a quick question. I have a 39 Gallon tank which is about half way through the cycling process (or so my LFS tells me) When it is fully cycled I will be putting a pair of True Perc Clowns in. I have a chunk of Live rock and hope to add a little more...
