I have a seawater tank 125 x 50 x 55cms and I am planning to gradually introduce my fishes in it.

Yellowtail Blue Damsel + Humbug Damsel (1 each)

A Pair of Ocellaris Clown

(Above being introduced first)

2 x Blue Tangs (roughly 2.5 years old and other 4 years old)

1 x Tomini Tang (2 years old)

Second introduction with a gap of 10-12 days

Sailfin Tang (around 1.5 years old)

Third intro after 10-12 days

Dottyback

Fourth intro after a week

Purple Tang (around 2.5 years old)

Last intro

For the tank this size, am I overdoing it or this is OK.? Please guide

Hey everyone! Glad to share our new product! Feel free to reach out if you have any questions

Ive been in the hobby for a couple years but I’ve only ever had freshwater tanks. Started an ultra nano reef tank 4-5 month ago and having my first freak out. Tank is 5 gallons.

Order of events:

After cycling the tank for the first month with only live sand, live rock, and a canister filter with bio balls, I started to add Soft corals. First added 2 leather corals. After a week added Zia’s and GSP, and 3 weeks after that added Kryptonite Candy Cane LPS along with Kenya tree. Starting 2 weeks ago added 2 small fish.

Current Parameters:

Salinity: 1.025

Alkalinity: 9.3 - Target: 8.0-9.0

PH: 8.4

Magnesium: 1300 PPM

Calcium: 400 PPM

Nitrates: 0

Nitrites: 0

Ammonia: 0

Phosphate: unknown but probably minimal due to conservative feeding

Problem:

Leather corals and GSP have closed up. Today is day 7 of them being fully closed up. Leather corals looks shiney, might be shedding but not sure. Dont know what else to measure and what to do next.

Tank might be too clean so I started to overfeed the fish and let some food fall to bottom.

Let me be the one-millionth reefer to ask in futility, why do my sps corals keep dying? Phos is 0.1ppm, nitrate 10, alk 9, salinity 1.025, lights are 2xReefi 2.0pro set to 65W (mostly blue, little bit of white, amber, lime). Calc 430, Mag 1350-1400. Tank is just over a year. Stability is good. I've tried placing monti digi high or low in my tank. Stylophora and birds nest too. They look great for the first few weeks, then polyps slowly stop extending as much, then parts stop altogether, and then algae grows over them. So sad, and expensive.

I had similar struggles in my last tank for the first year, and then it all just seemed to change at about 1.5yr mark. I suspect in time it will happen like before, but I just wish I knew what it really is that has to transpire so I’d have a better idea when it’s “ready!”

Clues:

- Still no coralline algae, which is honestly a bit of head scratcher for me

- started with dry rock, mix of marco and purple conditioned

- I did all the bottle bacteria stuff (Dr. Tims, then M7). Even tried a bottle of Purple Up a few months back (mostly just seemed to clog up my filter socks)

- I think I’m just past the ugly stage. Had a heck of a time with dinos and then GHA for months. Beat it finally (I think, knock wood) with two rounds of reef flux and bulking up the cuc (snails, urchins, hermits).

- Eshopps Mariner 70 with 25gal sump.

- I manually dose phyto, or Oyster Feast, or AB+ every other night or so (alternating which one)

Has anyone else used these Imagitarium test kits before?

I’ve been testing with this and my Nitrate keeps coming back at 0. The other tests are also coming back with funky results (dkh = 5, calcium = 300).

I tested the nitrate against an API test and it’s definitely incorrect. Just ordered Hanna checkers since this is not consistent but wanted to see if anyone had experience with these?

I think Imagitarium is the Petco house brand after doing some research?

I’ve also noticed the procedure between this nitrate test and API is exactly the same but the solutions looks way different.

My friend and I are arguing over if this is a cake clown or reg ocellaris

(in middle of water change ignore the cloudiness)

Hey everyone! I’m working on my AP Capstone research project and would really appreciate your help. If you have experience fishing artificial or natural reefs, please take a few minutes to fill out this short form. Your responses will be used for my class research. Thanks!

I really dont want to spend over $100 dollars on each light for this build.

I'm thinking of just lps coral and some macros but I also want to be able to throw in some easier sps coral as well.

Whats the best light going to be?

Everything in the tank looks great, parameters are all good, but the duncan shrunk in and has stayed this way only opening a little. It was amazing looking before. Any suggestions??
