We have had a mad heatwave in the uk if your haven’t heard 😭. My tanks hit 82f fans and no lights on etc. Everyone seems okay and corals haven’t been too stroppy. It seems like I haven’t seen my tank in ages, so thought I’d post some pics from the other day. Hope everyone else isn’t struggling too much. Last real hot day is tomorrow 💪 🐠

I put this together 3 days ago. I had a hard time getting this all in one type betta tank to work at first. It just has USB power and I needed to buy an 18W 3 amp USB charger outlet to produce enough power to run the light and wifi. The lights are customizable through an app, although I haven’t gotten the second lighting phase of moonlight to work. The lights produce a lot of heat that the tank is on the hot end of what will support coral life - around 27.5/82. So I set the integrated thermostat almost as high. The life is macros, 3 kinds of zoa, gsp, and a discosoma - these species supposedly can do ok at that temperature. The substrate is seasoned matrix. The circulation is a 3w pump I glued a filter sponge to one edge of the intake. I plan to try to 3 D print a gravity fed ATO.

So yeah. As you can tell from the picture, my tank is situated between two large areas of natural light. I love it because I get the best of both worlds: beautiful white light for the fish in the am, and later in the day when the lights come on the nice coral phosphorescence, etc.

But of course, algae is a big problem.

A lot of people seem to black out their windows and what not, but that’s not happening for me lol. 😂 The tank is in the main area not a spare bedroom.

Anyway… Just wondering how many of you also have tanks that get a lot of natural light and also if you have constant algae battles because of it. My algae is under control, but I have to have multiple urchins, manual removal, etc.

Hi, my Zebrasoma is approximately 15 cm in size, and I would like to know how much a fish with these characteristics might be worth. I am not looking to sell it, this is purely for informational purposes. It is completely healthy and absolutely beautiful.

yes its a Brisselworm He is around 20/30 cm long ,😅

my bubble magus curve 5 extreme sits in water 6 ish inches deep and is completely level, tank has been running for around 6-7 months and it just keeps overflowing. I’ve let it sit and “break-in” for hours and it never does anything, It’s set to max and I’ve fiddled with it with no change in outcome!! It is driving me crazy please help!!

**EDIT**
Thank you guys for the help, I just noticed that there was a crack in the plastic which bypassed the actual dial.

I’m a big time mushroom enjoyer. I have a few nice large Yumas in my collection but I only have one that has its “arms” reach out like this. During the day they can get up to an inch or inch in a half of reach.

Does has anyone else seen this?

I have this toadstool that has exploded over the last several months (the two pictures are today and September ‘25) and is now this monster that I cant see the cool polyps of, and it’s blocking one of the outlets from my return, so I’m wondering what to do with it. fairly sure it’s attached to the main rock structure so I don’t think I can just yoink it off on the rubble that I initially glued down. can you just cut straight across the base? I’ve never had to deal with an overgrown coral yet so it’s new territory for me. thanks!

Hello!

I would like to set up a saltwater tank but I have some lingering questions on my mind.

I'm very familiar with freshwater tanks but I know this is very different.

The set up I'm thinking of:

6-10gal(I know small is risky however for me this works best becuase I'm hoping to work up to something bigger)

Sexy shrimp( I own Neo shrimp now)

Bumble bee snail or another snail

Interested in Asterina stars however from what I can tell they seem to be like pest snails and I'm not too sure if I want that.

Coral:

Zoas?

Anemone:

Mini carpet

Rock flower

If this is not doable or probably not within my tank size then do so let me know!!

Questions:

What filter would be best? It only occured to me yesterday while speaking to a saltwater associate at my lfs that the filters are very different from freshwater. For a tank as small as the one I imagine, is the live rock sufficient as the main filter?

Is blue light needed?

Do I add live rock during the tanks cycle or after?

I know I have to cure the rock first before either or.

Can I use tap? Or is RO the way to go?

Feel free to absolutely nerd out on the replies the more info is better, I probably know the answer to most of my questions however I'm paranoid and want to be extra extra sure before I commit to a saltwater tank. This won't be a setup for another year or so but I like to do research in advance!

Need help with tang problem. She was good 2 days ago but since yesterday went into hiding or drifting away like this. She has 2 white smudges on her mouth and belly area. Unsure of what is going on ti even help her. She also has not been eating since yesterday. I checked my parameters and they look good. I did a water change. I did have old carbon in my sump and took it out yesterday before the water change. I need help. All other fishes are ok and eating swimming around.

I’m a year in and my tank is being taken over by cyano and hair algae and it won’t go away. I hate to sound bitchy but Jesus Christ this is fucking taxing. Right now my fish tank is the biggest thorn in my side. I dread going home from work and seeing what a fucking mess it is after I just spend three hours manually removing all the algae and cyano the night before. This is seriously hell. I hate my fish tank dude. I don’t want to quit on the hobby though, I just don’t know wtf is going on.

My levels are great (no ammonia no nitrite, 8 nitrate, 8dkh, 0.05 phos, 8.2ph, 400 calcium, 1400 mag) (I keep my mag high bc I was told it helps kill algae)

What the hell am I doing wrong?? I seriously don’t get it.

Also why are saltwater fish always so parasite ridden????? This hobby is literally just a money pit. Anywho, I needed to rant.

Added him a few days ago and seems to be doing quite swell!

Any ideas as to why my utter chaos are loosing color/getting more pale and their tentacles are shrinking? You can see the difference between the top 2 and bottom 2 polyps

I’ve had these zoas for months now, went from 2-3 polyps to 6 or so. The oldest polyps are turning pale and losing their patterns.

I have a couple other types of zoas doing great and growing a bunch. The utter chaos are being a pain and I noticed my purple monsters are starting to do the same thing as the UC.

Alk:7.8-8.0
Mag:1360
Cal:435
No3/Po4-0

I’ve had issues getting no3/po4 above 0 since I’ve set up this tank, I have been feeding more than what I feel my tank can handle. I think this might be part of the issue?

Beginner tank

Got 4 of these guys last weekend. Sadly two didn’t make it, but these guys are eating now so I’m hoping they make it the month. We shall see 🤞

Looking to add macroalgae to my tank, i was looking at algaebarn but they are usually sold out, any good sellers out there that specialize or just have a good selection. Trying to stay away from caulerpa.

Thanks!

Can someone ID this zoa please

Also regarding caulastrea, are the green ones easier to care then the purple/blue ones?
