Green palythoas are slowly taking over my 90 so I have decided to just upgrade. I found a 240g tall (72 x 24 x 31) on craigslist at a local thrift store I guess it was donated by someone so they were just trying to get rid of it, so I got it for a steal! The stand is solid teak and comes with...

Well the title says it all. I have those standard green palys in several parts of the tank and they colonize like weeds, in some cases growing right over other corals. A friend told me the only way is to take the rock out and rub the mat off with a towel.... My problem is I can't just take some...

Currently I have a 75 and have to get rid of the sand So instead of trying to remove and replace the substrate I started looking for a new tank that would fit on the current stand. Other than the sand issue this tank is badly scratched and has a few chips along the seems so I've never been...

I'm wondering what type of sand you all recommend for a reef? When I upgraded to my current tank 8 months ago I used play sand from lowes to save a few dollars, against the advice of many... Over time I noticed this nasty brown turf-like algae growing on the rocks which will not come off...

I've seen a couple.

So I have an occelaris clown that has been in the tank since the beginning, almost two years ago- just an awesome fish. So the last few days I noticed her lingering around a medium frogspawn which I've had for about 1 year and then I saw the clown laying in and swimming around in it so at first...

So I came home to find the mandarin dead (i know it was competing w the wrasse for pods and starved). The cuc has already started to work on it so I thought i'd ask if anyone just let's them finish? I would usually net out the fish and flush it but I figure why not? I really don't think I would...

Got this frag about a month ago and the lfs said its a birdsnest but after I look at pics online it looks closer like a stylophora, the end aren't pointy.

On Thursday my wife sprayed a lot of lysol all over the furniture in the living room where the tank is because a guest's kid threw up all over the place... I didn't really think about it because, even though I could smell it when I came home, the tank looked fine. Then on Friday she called me...

So I bought two tao dimmable led panels and retrofit them into a new hood to replace my quad t5 HO fixture. I did the switch about 2 weeks ago and the lights are about 8 inches from the surface of the water and the tank is 21" deep (75 G). I started with the lights dimmed all the way down and it...

So my 1 year old has an affinity for throwing objects into any body of water and sure enough I found my refractometer at the bottom of my sump today. I took it apart as best I could to allow it to dry so after a couple of hours I tried it out and it is totally dark I can barely see the figures...

I added a peppermint to eat an aptaisia but since adding him the aptasia is still here but some zoas have disappeared... I've read that some do and some don't.

I am building a new sump and have a couple questions that I cannot seem to find a clear answer on. My Dt is 55 g and not drilled so I am using a CPR overflow with a 1" bulkhead which I've read will yield 600 gph. I bought a mag 7 pump and the head loss is 4.5 feet which per the box will be 450...

So I have decided to take it to the next level and add a sump to my current 55. I have some softies and LPS that are doing good but not thriving and I just can't defeat the cyano. I will be adding a skimmer (crazy I've gone this long without one) and will also have a refugium in one compartment...

Picked up this new gorg for $9 thought I'd give it a shot. I add phyco pure twice a week. I put it on the bottom in a medium flow area. Any advice or experience is appreciated. Thanks!

Fish was swimming fine earlier today and ate fine. Then about 30 minutes ago I noticed it was lying on its side under a frogspawn. When I moved the fish it's mouth was gaping wide open and all fins are sticking out. His body is stiff and slightly twisted and it twitches occaisionally. Gramma...

Does anyone use natural seawater for water changes? I mean it is the water in the ocean that I am trying to recreate anyway right? So why not just get my water from the ocean? I live about 10 mins from the beach.

Currently awaiting some snails for diatoms but saw this this morning- is it Cyanobacteria? It's not growing anywhere else and I assume it's in this part bc it's the lowest flow area. Will nerites eat it? Also have a few nessarius on the way as well. Thanks!

So I've been thinking about adding one and my lfs has one. I currently have a small occelaris clown and a rusty angel that is a lot bigger than the blenny. My question is will the current fish pick on him too much? I do have a lot of lr for him to hide. Thanks!

Hey all, I noticed small spots before now the white is spreading. Here's a pic. Ive read that it could mean mag is low but I've never done anything for mag and I don't have a test kit for it (ordering). One thing that has changed is one of my blue bulbs went out so I put in another white...

It's all black w two white stripes on its back. I'd say the closest thing I can think of is isopod?? I tried to take a photo but couldn't get a good one. I was brushing some nuisance algae off a rock when it popped out. Any ideas?

What are some of your favorite beginner softies? My tank is 10 months old with t5 x 4 54 watt (3 whites 1 blue) Currently I only have a clown and a rusty angel cleaner shrimp some Zoa polyps and a ricordea. 55 gallon w 80 # lr 1.5 " live sand bed Thanks!

Just ordered one and am wondering the optimal place to put it. I've read the sand bed or somewhere low with low-moderate light and moderate flow. Also, do they self acclimate or should I drip him? Thanks!

Hey all I added a condylactis anemone on Saturday I floated the bag for 15 mins and drip acclimated him for about 1.5 hours before adding him to the tank. I left the lights on their regular schedule 10 hours plus 1 hr for "dawn" and one for "dusk" t5 54 w 2x white 2 x actinic blue. I decided...
