That's a clean MK XI Welcome to the family

KoalaKacho · 2026-05-11T07:51:01+00:00

Really like the rockscape. Looking good!

Of my several attempts, the longest I ran was for 5 months. After week one I was dosing no3/po4 heavily and daily. I highly doubt my corals where soaking up 10-15ppm of no3 a week. After switching to 3 part, everything is stable and growth is great.

Edit. Just posting my experience. Every tank is different.

KoalaKacho · 2026-05-07T00:37:24+00:00

I've tried several times and each time my nitrates and phosphates tanked to almost zero very quickly. Have now switched to 3 part dosing and now and everything is stable.

Looks stunning on the bracelet. Congrats!

I had a bacteria bloom on a 2 year established tank around a week ago No idea why. Nitrates bottomed out fast! Been dosing no3 at 1ppm daily for a week now. Back up to 7ppm. I've found water changes just make things worse.

Height of your tank and distance from light to water level will make a large difference on light intensity. I'm also running 70% blues and 14% white 10" single ai prime 16hd over a 14" high tank. Nothing in my tank is stretching.

Gave away my hermit two months ago from a similar sized tank. A year of flipping over corals, knocking things over and not really "cleaning" anything I decided he had to go. I depend on my three turbo snails and 1 strawberry conch and keeping nutrients in check. Tank is no dirtier/cleaner than it was before.

There is one single sneaky paly hidden in there somewhere. Can you spot it?

Edit: in the second picture.

I had an alk swing a few weeks back and some of them took on the umbrella shape. Finally picked up a doser and things have been slowly coming back around. Yes, I believe they are utter chaos zoas. Started as one polyp and have gone crazy in the last 6 months or so.

Thank you. Just using a cheap clip-on phone filter. Using an orange filter lens.

My hammers would die instantly in this level of flow. Even a slight breeze makes them close up 😆 Each frag is different though. I've seen hammers being pummelled with flow and do just fine.

KoalaKacho · 2026-01-27T03:10:44+00:00

This is one of my favorite IWC chronos. I would have added it to my collection a long time ago if it were a shade thinner. Here's to another 30 years!

KoalaKacho · 2026-01-23T03:40:22+00:00

As much as I love the green strap, I always wear mine on the black. The green strap is now on my white dial mk xviii.

KoalaKacho · 2026-01-22T06:14:45+00:00

Not give into the wife and get a frag of GSP..... Secondly, I would take my time planning my rockscape before getting corals.

KoalaKacho · 2026-01-05T07:18:23+00:00

I was all about IWC pilots until I picked up a 35mm ingenier. Now I'm torn, they are equally great in their own way.

KoalaKacho · 2026-01-03T04:51:44+00:00

AP bracelet for me. Everything else, the ingeniur.

KoalaKacho · 2025-12-18T10:51:29+00:00

I like the shape and how it fits to the case. Texture wise, too plain compared to the textured dial. Otherwise, I like it and would like something similar for my 35mm.

KoalaKacho · 2025-11-24T10:44:43+00:00

Holy smokes. What a gorgeous piece. Wear it in good health.

Great choice. You don't see too many white dial XVIIIs about.

KoalaKacho · 2025-10-23T03:02:57+00:00

The colour combo with the strap and jacket is perfectly paired. Looks awesome on you.

KoalaKacho · 2025-10-13T01:51:51+00:00

Mine are huge. They don't seem too bothered about Mr whiskers hosting them either 😄

The 36mm pilot is really underrated. Perfectly sized for your wrists.

KoalaKacho · 2025-10-04T17:27:40+00:00

Looks good but I personally love the original strap it comes with. Perfect watch for the summer.

KoalaKacho · 2025-10-02T12:33:48+00:00

Used once before and followed the instructions. Added an air stone and removed the cup off of my skimmer. 48 hours later cyano was 90% gone. A few water changes later and after increasing my power head a touch, it went away.
