i got a bunch of corals from an online retailer a couple months ago and everything is happy and nice but this one $20 frag is causing me some trouble battling bubble algae and now what i think is Aptaisa. my fear is that it will contaminate the whole tank. is it worth trying to keep a small...

I have a nuvo 20 pro that sits on an aquarium stand and the leveling mat innovative marine sells with it. My display water level is off. I measured it and one side is 1 inch versus the other side being 1 inch and 1/4. I put a level to the tank and stand and all seems level. Is there something...

Hi Reefers, So I bought this colt coral few weeks ago, and I noticed that there is somewhat looking thingy next to it, so I though oh maybe that’s his kid or something (don’t judge me please ) But at night I realize it doesn’t scrunch in like the colt. Does anyone know what is that? should I...

I drilled my return line a little too high. I have a rimmed tank and the nut side of the bulkhead hits the trim so I can get it flush to the glass. Any ideas on how to remedy this?

Saw this spiky coralline algae on my frag, and it almost looks meaty. A bit clear and sticks out 2mm and 3-4mm on spikes. What is this? Should i remove it? I can get a beter photo later.

Hello everyone so I am soon going to purchase an RODI system for underneath my bathroom sink and before I get it I want to know where I should drill the hole for the drain line on the filter. I know putting it straight into the sink is an option but I’d rather have it look tidier. Some people...

Hey. I made an embarrassing mistake. When I put in my new heater for my reef tank, I somehow forgot to put the temperature reading gauge in the tank to monitor the temp and base the heat off the gauge. Therefore my heater was constantly heating up and my tank ended up at 96°F… Thank god I was...

Hi everyone, I have like 3 emerald crabs, and I noticed only one of them have this like algae or hairy stuff growing on its back. Does anyone know what is that? should I be concerned? should I remove him? On that note, would they eat seaweed? i’m concerned that they don’t have enough food and...

Found this crawling around in my sea urchin. It was flat and looked like a big flatworm. Dropped a bunch of eggs when I dipped the urchin in fresh water to knock it off. Sorry no better pictures.

A lot of the tissue has receded on this octospawn but there is still plenty there, about half. Easier to see when fully closed, it still somewhat opens, any dips or something i can do to recover it? I believe it was a bacterial infection no signs of brown jelly though. Thanks for...

Got this rock last week and I'm new in reef tanks, I don't know if this is too much or not.

Hi guys, i have moved my elegance coral on the of a rock and added one more light to my aquarium but it didnt like the water movement there(too much flow i guess) It wasnt looking healthy and then i placed it on the sand in the corner of my aquarium but here are the photos of it. What can...

The green octospawn has been retracted ever since a couple days i bout it, and is only getting worse. At night the tissue looks to be diying and is showing no signs of improving. I have a photo during day and night. Parameters: Ph 8.0 Ammonia 0ppm Nitrite 0ppm Nitrate 2ppm Calcium 390ppm Alk...

Been having a problem with some of my sps turning a grey color. Not really turning white like they’re dying but more grey. My phosphates are about .05 and my nitrates are hovering about 30 on the Hanna tester. They’re sitting in about 300 par with Radion WWC schedule light and Orphek bars. I...

Hi. I got a tank from my co worker but it’s not what the box says! Tried finding specs online but nothing matches up with what I have. Narrowed down to a Red Sea due to the style, but I don’t know which model this is. The box it came in says JBJ 45G AIO Flat Panel, but it definitely isn’t. Pics...

recently bought the bright green octospawn, and it was happy and open for about a week until it started not opening fully. Newly added frogspawn is happy though, they are in the same flow, light, and all else, figure it is a chemical issue since it was happy when i first got it. At night it even...

Hi guys i am planning to get one snowflake eel for my 250 liter tank. I have 2 clowns, fire shrimp, conches, snails, starfishes and one blue tang. + LPS corals mostly. Is it okay for my pets to live with a snowflake eel? Is it safe

Hey everyone, I've recently been given a 5 gallon tank and so I thought I'd do some research on what to keep in it. I need to make sure whatever is kept in it is comfortable and lives a long life. I am open to any sort of guide on even if 5 gallons would be enough for saltwater creatures. Does...

I have had my fish tanking going for about 4 months now and although I am quite new to keeping fish I had done a lot of research prior to owning them. It is important to note that about 3 months ago I had what I believe to have been Columinaris which went through my tank and killed all but a few...

Hey all! Looking for some advice here as I haven't really found consistent answers in other threads I've been checking out. Today is May 15 and by the end of June I will be moving to a new place. I'm taking this opportunity to upgrade my tank and have some questions about the process and...

I have had this trumpet for a long time, originally in a pretty low light 5 gal, until about a year ago i moved it to the big tank. Was happy for the first couple months but its condition has slowly deteriorated after a magnesium spike, and magnesium is still a bit high. Moved it to 60 par low...

Hello, The latest introductions to my tank are a hi fin banded goby and what was meant to be a randalls pistol shrimp. While the two have paired, myself and other reef keepers have decided its colours and patterns are much more tiger like — especially with how large it is. (I have attempted...

Noticed my damsel wasn’t swimming around. Found it like this (see picture). Still swims, sometimes upside down. Very lethargic/easy to catch. It is in a “newbie mistake” overcrowded tank, but it’s generally peaceful. I’ve qt’d the damsel and have dosed my tank with Reef Rally Pro. I’m...

Hello all! In one of my tanks, I was building up a collection of Godzilla yumas, as well as about 5 other types of yumas. Seemingly overnight, all of my godzilla yumas looked shrunken and awful, and they have since continued to melt away. Only this one specific type of yuma has been dying. All...
