Hi everyone! I'm excited to show off what I have going on. This is my first real post, so hopefully I manage to get the formatting down. I figured I would make this a bit of an introduction and document my new build as I get it going. Please let me know if anyone has any recommendations!

Background:
  • I have always had an interest in fish tanks and aquatic life ever since I was a little kid. I had several different iterations of the stereotypical little-kid tanks. Small, barely taken care of, freshwater setups. Unfortunately, this was before the modern internet, and my parents didn't know much or really help out much. As I got older, I learned a few things and did manage to have a little bit of success with these.
  • When I was in high school, I tried to step it up a bit with a planted freshwater system. This was successful for a time, but the realities of being in that unstable period of life (high school, college, starting career, etc.) caught up with me and I left the hobby for several years.
  • Several years ago, I picked it back up with a 60-gallon fancy goldfish setup. This was my favorite tank to this point, and I finally had the stability and adult time/money to properly take care of it. However, a cross-country move put that to an end.
First Reef Tank (20 Gallon HOB):
  • Fast-forward to a little over a year ago, and I got the itch to get back into the fishkeeping hobby. However, this time, I decided to look more into what I had really wanted all this time - a saltwater fish tank.
  • After much deliberation, I decided the best thing for me would be to keep it as cheap as possible as a "trial run" to make sure I could figure it out. This meant a few things - it had to be small, and it had to use HOB equipment.
  • After about a year of this setup, I have managed to take several tiny coral frags and have them grow a decent bit. I have had a couple that are growing much slower as well, but I am happy to say that I haven't killed a coral (yet) and I feel ready to use a bit more tech to make things more stable, and have a larger setup. I think the hammer would have grown more if the clowns weren't hosting it. The tank is generally doing great and has healthy coralline algae growth as well.
  • I'm getting tired of not having an ATO🤣
  • Current fish are a pair of Oceallaris Clownfish and a Splendid Dottyback. Other livestock include assorted CUC and corals.
  • Equipment includes (2) Fluval HOB filters (one as a small refugium), (1) AI Prime, AI Orbit 2, and a 200w Titanium heater ran off a controller. I had a cheap HOB skimmer for a few months, mostly for attempting to raise pH. The skimmer pump died and I never replaced it.
20g when it was first setup:

20g I purchased my first few small frags:

20g today (a little messy, but doing well):

Deciding on the Upgrade:
  • Now for the exciting part! I started really planning for this upgrade a few months ago, and it is finally almost ready to transfer the livestock over.
  • I wanted my upgrade to have enough room for a couple of larger fish (small tangs, dwarf angel, etc.) and I needed to get away from HOB. I went back and forth on if I would consider an AIO, but ultimately decided I wanted to be able to hide everything in the sump and the added flexibility of equipment. I also decided I wanted a peninsula styled tank for viewing puposes from my desk.
  • I landed on the Mariner MP100 from Eshopps.
Now the Problems Begin...
  • The first problem I had to figure out is that the location I wanted to place this peninsula tank meant it was running parallel to the floor joists. Luckily, it is on the first floor and next to a load-bearing wall, so at least I had a couple things going for me. After a lot of messing around in the crawl space and measuring, I figured out the floor was supported by 2x10 I-Joists spaced 20" OC, and that the tank would be approximately centered on one of these joists, technically only supported by a single joist. Definitely needed to reinforce.
  • I ended up using some 2x6 lumber supported by 3 floor jacks to spread the load between 3 joists. I then also added 2 more floor jacks and 2x10s to directly support the subfloor after the tank was placed when I noticed I could shake the tank more than I would like if I bounced my weight around with my feet right next to the stand. After thinking through what was causing it, I decided the fact it was on carpet and the fact that the leveling feet were as far away from the joists as possible was what was causing it. The new supports helped reduce this by about 50%. I would say this is now acceptable, although the paranoid part of me still wants to add even more supports.
  • When the tank arrived, it unfortunately had sustained damage to a corner seam in shipping. However, the Eshopps customer service has been fantastic, and long story short, I now have a new tank with no damage.
Floor support:

New MP100 Equipment Details:
  • Now to get to the fun stuff! Here is what I am working with right now:
    • Tank: Eshopps Mariner MP100 (100 gallon display, 48"x22"x22", 30 gallon sump)
    • Lighting: (1) AI Blade Coral Grow, 48" (tested par as ~500 at surface, ~200 mid, ~125 sandbed. Very impressed. Might get more down the road if needed)
    • Flow: (2) AI Orbit 2
    • Return Pump: Sicce Syncra SDC 6.0
    • Skimmer: Not purchased yet, will eventually run one. Most likely Simplicity DC skimmer.
    • Heater: 2x300w Titanium heaters controlled via IM Helio Controller.
    • Refugium: Transferring from old setup. Has an IM Refugium LED.
    • ATO: Osmolator 3 w/ Simplicity 10g Reservoir
  • I now have everything setup, basic rockscape, and have added some bottled bacteria and ammonia, along with a few miscellaneous rocks in the refugium from my old tank to help speed along cycling. I thought about adding everything all at once immediately, but decided doing a basic cycle of the new rock would help offset problems caused by such a large upgrade. I am hoping to add everything from the old tank at the same time once ammonia hits 0.

New setup (cable management needs some work):

I think that's everything! Hopefully, the pictures all show up right. 😅

Let me know what you think! Looking forward to hopefully getting a little involved on Reef2Reef!

Congrats on the new tank. The MP100 is one that is on my list as a possible replacement for my failing RS tank. I don't really have a place to set it so all 3 sides are viewable but a being a peninsula it will allow me to place it closer to the walls in the corner where it will be placed.

Thanks! I would definitely recommend it so far. Customer service is great and the tank and stand both seem to be very well built. I considered going the Red Sea route at first, but after researching it I was not willing to gamble on the seams being better with the G3s. Time will tell if they actually fixed the problems.

Wise decision. I'm on my second failure now. First was Gen 1 reefer 170 My current one is a Gen 2 reefer 300.
Yikes. I assumed at least part of it would be the volume of tanks they produce, but 1 person having 2 failures in a row is not a good look for Red Sea. How many years apart are the two failures?

Looking good! Can't wait to see how it progresses. I too need to find some serious solutions for cord management. Lol
It's low on the priority list lol. I underestimated how tight the space inside the stand can be with a sump. At first I planned on having everything cleanly inside of the stand, but then it became clear that wasn't going to happen without a lot more forethought on cable and controller placement.

Probably a year or so apart. The first tank was running for 6 years. the current one about 3 years. There have been some reports of people that received warranty replacement tanks and the replacement tanks also failed. The tank is doing really well so I'm not looking forward to moving everything out.

Yeah I can't imagine. I just checked out your tank and it looks amazing! I feel bad enough moving over this tank since it seems like it is snowballing and doing better and better and this is going to reset it. Having to move it after 3 years would be so much worse. Plus your tank looks a lot better than my current setup!

@Silentpanda619 Just ordered one of these tanks, how are you liking it? Was it pretty straight forward getting it going? Are you happy with the sicce return pump?

Things are going pretty well! I'm still really liking the tank, and have been meaning to post an update. I'll get to that sometime soon.

The only small complaint I would have is that the ball valves that it comes with for adjusting the overflow to the sump are extremely sensitive and it is hard to make very small adjustments. The Sicce SDC has been great and certainly helps with dialing in flow.

Note on the Sicce SDC 6.0 - the adapters it comes with are not compatible with the soft hose for the return that comes with the Mariner MP100. Off the top of my head (don't quote me on the numbers), I believe the SDC 6.0 only goes down to 3/4", and the Mariner is plumbed for 5/8". I had to buy a couple of pieces to make it all work. I believe the smaller Sicce pumps may come with a 5/8" adapter.

The biggest headache for getting everything going was dealing with the sizing issue on the return line.

Awesome! Glad you’re still liking it and can’t wait to see some more pictures.

That’s a bummer on the fittings, I will weigh the options on the return pump and see what’s best. One of the guys at Eshopps mentioned a reef octopus pump and skimmer if I want Dc controlled. They are pretty pricey though.

Here's an update about 2 months in!

Equipment Added:
  • Simplicity 120DC Skimmer
  • Refugium is up and running (Innovative Marine refugium light - currently no macro as water lettuce died off for some reason?)
  • (1) Ecotech Versa (dosing All For Reef - currently 46ml/day continuously)
Livestock Added:
  • Blue-Eyed Kole Tang (Juvenile)
  • Lamarck's Angelfish (Juvenile)
  • Misc. CUC (need more soon - film algae has taken over rock work. Turbos are helping some)
  • A few small coral frags (won't go into details on this update. Maybe once they have grown more. Mostly SPS.)
Other Updates:
  • The Splendid Dottyback was VERY aggressive to the new tang and angel when they were first added. Unfortunately, a lot of fin damage ensued. However, by day 2, everyone calmed down substantially and they are mostly recovered. I hypothesize I left the dottyback and clowns as the only inhabitants in the tank for too long. I am cautiously optimistic that the next additions will go better.
  • I have not yet mastered cable management. Everything is covered by a curtain for now. Maybe forever if I am too lazy? It's better than nothing, right? 🥲
  • I am keeping track of it, but I am currently experiencing relatively high magnesium usage for unknown reasons.
  • The tank hasn't fallen through the floor (yet!)
  • Nutrients are very stable, so I am minimal with water changes right now (10% 1-2 times a month)
Next on the "To-Do" List:
  • Add lid (Kraken?)
  • Add more CUC (looking for a few unique inverts besides hermits and snails)
  • Add more fish before the Tang and Angel get too large
    • Thinking maybe a Blenny and a small school of Anthias?
    • Open to suggestions!
Parameters:
  • Alkalinity - 8.7 dKH
  • Calcium - 450 ppm
  • Magnesium - 1230 ppm
  • Nitrate - Trace (want to get Hanna Tester for better readings)
  • Phosphate - 0.03 ppm
  • Salinity - 1.026 SG
  • Temperature - 78 F
