Hey Guys!
As everyone knows, cant stay away from the hobby for very long. I had a busy couple years that involved a move, large reno's and my first kid, so naturally, i have been tank-less for a couple years. (freshwater to tide me over, but that hardly counts)

After a trip to mexico, snorkeling hours every day, i decide to jump back in again.

This time, however i am going to approach it quite differently.

Sump-less!

Ill go over my thought process in case anyone else is/ was on the fence as well.

Pros vs Cons.

Pros:

COST. This is a huge factor for most, including myself. The startup $ for a reasonably sized sump-less tank is significantly less than a full system.

LEAKS. With no plumbing, no water leaving the tank, way less chance for leaking.

SETUP:
much simpler to setup, a successful sump-less will appeal much more to newcomers to the hobby, and is less daunting.

POWER COST: less pumps, less power, less water volume, lower watt heater etc etc.

Cons:

If not done properly, less aesthetically pleasing.

Not as easy to hide equipment, less equipment options.

Less water volume, this one is subjective, but more is generally better.

Overall, there is alot of tailored product, specifically to sump-less tanks.
Ill post my build here, follow along, remind me of stuff ive forgotten. Suggestions are always welcome :)

The Build plan

75gallon cube (24x24x30H)

Going to run:
a skimmer, either reef octo, or SWC, something square and oversized of course.
ATO with a surface skimmer, to get rid of the surface film
https://www.amazon.ca/XP-Aqua-Sumpless-ATO-Auto-Top-Off/dp/B07H8NZD5M

Heater, some black and easily hideable against the back wall.

LED lights, most likely china black boxes, but considering razor as well.

2 wavemakers, jebeo is my leading option, but i wont turn down a pair of used mp10s

75 lbs+ of liverock, sand ( to hell with barebottoms ;)
Will also have a TLF reactor and GFO on standby, not nessesarily always hooked up.
Aiming for the least equip possible.

Stock:

Mix of lps and sps, and of course my personal fav zoas.

clown pair with nem
midas blenny
leopard wrasse
mandarin (after a year or so)
1 tang, start small , rehome after it outgrows.
dwarf angel
bangai cardinels

want to keep fish stock relatively light, that always makes life easier.

Will Shoot for 10g water changes weekly, and will explore vodka dosing.
I do not plan on dosing much else, but will cross that bridge later.

Little dude checking out the new digs. Loves the fresh water tank, so can only imagine what the colours and movement from a sw will do

I have a pair of 16 inch lights and 75+ pounds of rock if interested in going used. I'm just getting out of hobby. Hopefully dont regret it and start again in a couple years like most seem to do.

Painted the back of the tank, being a square, I just picked the post scratched side lol
5 coats later and voila

Also, rising sand and rock in 0 C sucks, but hey, reefers gotta do what a reefers gotta do!

Moved the tank in place, stand isn't finished yet ( obviously) going to be a canopy over top, and entirety of it will be covered with barn board/ pine board for rustic type of finish. Goal is to make every thing open, so hinges everywhere lol

The fresh water tank is not staying there, it's forsale if anyone is interested lol.

Leak tested for 24 hours. Then added saltwater, and sand. Let sit for 24+ hours.

Just putting the room in context, basement is the only room in the house I have jurisdiction of , it's an odd rule, but one that works for us.

Added the liverock and semi scaped it, it will change, can't decide on what I want/ like, and I hate glueing pieces together, as that's way to permanent for.me, but due to the height of the tank i may have to get over that hatred to utilize the top half of the aquarium

HOB with filter floss is just there to help clear the water during setup,

Only intend to run a skimmer, ato, heater and powerheads.

Lights hung, skimmers on but not operating yet.

Cycle is well underway, using 'seed'.


Tons of flow with the cp25 and one rw8
Both on very Low settings.

1 week setup, no ammonia no nitrites, 20 nitrates.
Seed seems to working well !
Added 3 chromis and a firefish which are doing great after 24 hours!

Skimmer is pulling out some nasty stuff already.

Got myself a 300w cobalt ( used of course #reefscavenger) blends in great, from the front you can hardly see anything on the back , black on black. Took a side shot to show what's actually there.
Skimmer, heater, overflow box for the auto top of. And surface skim.


And on another note the diatoms have hit :)

Few lps and zoa frags added.
Still playing with the lighting scheduled a bit.
Trying to replicate nature as best I can.

So I know diatom blooms are very normal.
Also know they have to run their course, been through this enough.
But this time I'm finding the water extremely cloudy on top of diatoms on all surface areas.

Are water born diatoms a thing?

I stuck a piece of foam in the skimmer outlet chamber, within 5 hours I noticed it was visibly clearer, as well as less diatoms on the rocks and upon wringing the floss out, the Pail was a sludge brown.

Any insight?
