question

Hello all, I have a 10g fairly new tank. Worry not everything is cycled of course but I started noticing orange patches here and there on my sand. All levels are within normal ranges so I have no idea what this might be, but then again I still consider myself a beginner and I don’t know much...

Hey everyone, so quick question I was having a breakout of Dino’s and I’m sure cyano over the pat 6 months. I ended up breaking down the tank as I’m setting up a 60 cube. I took all the rock out that had all the Dino slime and hosed it off and it’s pretty much outside. Can I reuse the rock...

Hi everyone, I’ve had this school of about 20 blue/green chromis I got around a year ago. They are currently in a 225G and being fed with frozen brime, cyclops, scraps of seaweed left the tangs, and small stuff in the water column throughout the day. So far there’s has been no aggression. I...

Hi there. I recently set up a tank dedicated to a Harlequin pair. I received both through a package and after acclimating them, I noticed that the female was displaying behavior indicating she was preparing to molt (slow and limited movement, hiding in rockwork, etc.). She molted 2 days after...

Hi all so today I was of course in my tank with no gloves which was dumb of me but I was just sticking a frag to its new home. Anyway I scraped my index finger by the cuticle and immediately took my hand out and washed it with water and soap and put neosporin on it. fast forward this morning, I...

Back when I started almost a year ago, I didn't realize how big of a deal drip acclimation and having a QT process was. Due to that, two fish and a shrimp were lost. I was just curious what others did or did not do at the start of their reefing hobby that now seems impossible to forget due to...

Are flatworms really that bad? They look ugly but don’t seem to be effecting anything. I have those yellow rasses and those blue damsels. Those guys don’t eat the flatworms. When I feed I’ll dip rocks in RO and take a couple dead flatworms and drop them in with the food to get them accustomed to...

I know I need a light, sand, and rock. Which light would work? Would this be a nano or aoi build for a build thread? What else do I need? I want to do a budget build. I plan on having Zoa’s and Ricordia One clown. would a yellow watchman gobie and pistol shrimp be too much? thanks

Hey guys ! I really would love your ideas, input, Suggestions on coral businesses. I plan on starting a veteran owned and operated coral business in the next year or so. I want it to be like no other business out there. All coral will be aquacultured and priced to compete with wild caught...

I'm doing research ahead of time before buying and setting up my first saltwater tank. It will be FOWLR, with the exception of possibly an anemone down the road at some point if/when I'm confident I can take care of one properly. The display tank will be in the range of 20-30 gallons and the...

Hi everyone, I have recently added an SRBTA to my 20 gallon AIO. The nem looked healthy when receiving shipment and did well during the acclimation process and has found itself a nice spot in the rocks. I have a RedSea ReefLED50 and will attach a photo of my lighting schedule below. I’m a little...

Just saw this floating around in the bottom of my bare bottom tank. Took it out for some inspection. Included pictures of what I would along with the rock if that would help identification. Thanks!

My clownfish recently became more interested in my torch coral. Yesterday they started swimming through it and nuzzling. I was aware that this can potentially kill the torch so I was considering adding an anemone if the clowns started to do this. Unfourtentally, I'm now a week away from a trip I...

Can I measure my salinity by just putting the hydrometer in the tank itself or do I have to fill something up with my tank water and put it in that?

Don't have much expectations asking this question, but when it comes to bubble algae, how do they grow? To give an example to my question: A couple days ago I found a fairly small shell covered in bubble algae. I removed it very carefully from my tank and looked around. I didn't see the algae...

Hello! I got my first Favia coral today. I’ve only had it for a few hours, but it doesn’t look great. It looks like some of the green has just turned into white gunk. I don’t believe it was like this when I got it, or it happened though-out the 5 hours I’ve had it. Is this bad, and anything I...

I started my reef tank back in April and it has been nothing short of a nightmare from the get go. I added a pair of clowns to the tank a few days after the startup bacteria to help with the cycling process. I elected not to QT the fish since there was nothing else in there to contaminate at the...

Hey everyone! Has anyone experimented with using a Ziss Brine Shrimp Hatchery to culture Copepods or phytoplankton? I feel like it would be super convenient the way it’s made!

Wondering what everyones thoughts are on the Tunze 9012 skimmer. I have a 135 gallon tank that has an AIO box in it with no sump and I'm looking for options for a skimmer that has to fit inside of a 6"x6" chamber. Is it a good skimmer? Are there better options for me?

What are the best hermit crab species that actively eat algae and help with things like GHA and diatoms? They also need to be small and reef safe. My snails don't do much.

I have a 16 gallon biocube with some snails that don't eat a lot of algae, zoanthids and a blastomussa coral, and a citron goby. My question is, I have a lot of algae growth on my sand bed and it looks like I am getting some hair algae on my rocks. I just got the corals yesterday. If I were to...

I am getting some dry shelf rock next Thursday and I also have a citrinis clown goby and some corals, When I add the rock, will it stress my goby or corals out too much?

I am currently acclimating some zoanthids and a blastomussa coral, I have the lights off in the tank right now. Once I get them in the tank, can I turn on the white lights or should a set it to blue lights? Or can they just go without light for another 2 hours?

I just got a citrinis clown goby today. I dont have any corals yet, but I am going to get some very soon. Is there any types of LPS or soft corals they prefer to perch on, or will they perch on all kinds of coral.
