Has anyone had any experience with Marine Pure Block for removing Nitrates? I can see where this product would be great for removing ammonia & nitrites. But when using their BLOCK version of their product 8"x8"x4" it claims to help with nitrates too. Claiming oxygen cannot penetrate deep...

Now that my tank has been up and running for more than a year, I have realized that I should have gone with a thicker sand bed when I first set it up. I have been fighting dinoflagulates (sp?) on and off for 3 months if not longer. I just did my third black out but don't think its totally...

Well, the time has come. School is out and vacation is over so I decided it is about time I make a tank thread. My name is Grant. Ive been in the hobby for ~8 years. I started when I was 10 years old as my dads helper. We had a 75 gal acrylic mixed reef, started around 2006-2007. After a few...

Okay, so I have been battling red slime algae all year. Earlier this week I dumped a bunch of copepods that I ordered online into the tank. Now, the slime is substantially reduced. But not gone completely. My guess is that the pods are eating the detritus that was fueling the slime growth. I...

I realize I might be setting myself up to get flamed but Im redoing this 60 gallon cube tank of mine. I cant utilize a sump so I figure if I use a medium aquafuge 2 hob refugium with a bunch of chaeto and a dsb with plenty of live rock in the display tank and a tunze 9004 hob skimmer that will...

Hello, I am a 3 year reefer and have a 120g tank. I went out of town for the first time since I started this hobby and had my sisters feeding the fish. I just got a call from them saying that they didn't see any life when feeding the tank most recently and that the tank felt hot. It sounds like...

Ok guys I have a 55gal salt tank thats 9 days in and im getting ready to re scape the live rock that I have. Only about 25 pounds currently but getting more. The tank already had a thin layer (40lbs) of live sand on the bottom and I bought a bag of crushed coral and threw it on top. Would it...

Hi guys, I'm hoping someone here may be able to answer some Qs for me... I have a mated pair of black clowns (over 2 years old) The smaller of the two has a habit of drifting down to the sand bed near the glass and stirring it up. Does anyone know what this behavior means? Also is this a...

I need input on what type of sand I should choose for my new tank. I know I want sand and not BB or CC. I would like to get either as white a possible or somthing with some color in it. Im not crazy about the brown or gray looking sand verities and enjoy the look of the finer grain types. I'm...

Fish Advice! Hello, I upgraded to a 120gallon several months ago (from a 29 cube). I have moved away from zoos and softies and am primarily doing a SPS tank with a few LPS. So far everything in the tank is going great, however, I only have 3 fish. 2 blue/green chromis and a sailfin tang...

Hey michigan reefers! I'm starting my first reef tank and I'm having lots of trouble getting my deep sand bed going with the life that is essential for it to work. I've tried buying live rock and sand from the lfs to seed, but its a large sand bed and the rock I've found has not been very good...

Hi, I have a 120 mixed reef with about 180 lbs of rock and a variety of corals and have been vinegar dosing, and brought them down to zero nitrates, however with vinegar dosing you can get some side effects and want to go back to a refugium, I use to have one on my mixed 180 reef and it worked...

On my 150 gallon I just completely redid everything is doing well. Except I looked in the fuge, a couple days after I put some rock into my tank that I dried out because it was in the tank when the previous owner crashed the whole tank, and there is a dark yellow slime or algae on the glass and...

So, I've got a 120 with a 40 sump. Connected to the sump I have a separate 12 gallon fuge that is split in 2. I was thinking that on one side I'll grow cheato with a bit of live rock and on the other side I'll have a 9x9 area with a very deep sand bed. 7" or so. Here's my issue, I hear mixed...

I'm in the process of setting up a new 90, and I need some opinions about substrate. Should I go with sand or crushed coral. I like how they both look, and I'm trying to do everything right this time around in my new build. I've been reading sand is better than crushed coral, and if you use cc...

I have not had a system up for 10 years. I am starting to do my research. There has been a great evolution in pumps, skimmers and lighting. Nice technology. My last and best system consisted of, 65 gallon acrylic show tank with overflow, Sump built into acrylic stand Pathetic skimmer return pump...

Final touches on the tank, and making sure everything is good to go. Hopefully will have the lights on the tank this weekend, and my first fish and a very light CuC. Question, though. I placed egg crate on the bottom of my tank as I may have burrowers, including a pistol shrimp and I was highly...
