135 Gallon 72"x18"x24" 6 years old

Parameter levels:
Ca - 400ppm
Alk - 7.8-8.0
pH - 8.1-8.3
Mg - 1300
NO3 - rarely test anymore
PO4 - rarely test anymore
Salinity - 1.025

Lighting: ATI 8x80w Two bulbs ON 9am-11pm, remaining bulbs on 10am-8pm

Water Changes: 1 gallon per day (Apex Dos)

Controller: Apex

Dosing:
Calcium reactor

Flow: 2x Apex Wav running on pulse at 100% inverse

I had the most success when I stopped messing with things. I rarely test NO3 and PO4 anymore because I was always chasing numbers up and down and constantly taking away stability. I no longer dose anything or take any extra measures. I have tried many of common methods i.e. ZEO, carbon dosing etc. but never had any real success. Everybody always mentions patience in this hobby. I think my success started coming when I truley learned patience and just let the tank be and let things settle out instead of intervening.

So no zeovit. what exacatly is inverse mode on the wav do? I have the same pumps.
I really like your tank

VERY TRUE STATEMENT ON STABILITY. SO MANY OUT THERE WHO SAY IMPOSSIBLE TO KEEP SPS THRIVING. ONE LITTLE TWEEK OR CHANGE IS ENOUGH TO CHANGE THEIR BEHAVIOR AND SURVIVABILITY

 

[Rakie]

1) Stability -- Params don't even have to be "perfect" for results. Just stable.
2) Some nutrients -- Ever notice how every 2nd or 3rd post on this entire sub is as follows? "HALP SPS DYING AND PALE, NO3 & PO4 = ZERO WUTS WRONG".

So on 1... I was foolish and didn't calibrate my refractometer for like 6-7 months. My salinity slipped to 1.021 and I still had growth and color. why? Stability. Even mediocre stability is better than instability.

And on 2... SPS like nutrients. When I was first in this hobby in middle school the only answer was zero no3/po4. Now the goto seems to be around 10 no3 and .05 po4, and in the article here with the "masters" most of them are around 20+ no3 and above .05 po5. Not a single one promotes zero/zero anymore.

I think that's everything about my system. Here are some older pics. Current tank has been setup for just under a year now. It has grown in quite a bit (need to take some updated pics). Link to the AdvancedAquarist tank article is below in my signature (LOTS of pics and more info there). Hope this helps : )

beautiful build! healthy corals!

I'm definitely a lightweight in this discussion, but I've had my 180g up for just over a year and it was first real attempt at keeping SPS. I've been successfully keeping saltwater tanks for over a decade, but previous reef tanks were LPS & Zoa dominated. Over the first year, my growth and coloration has been good and my tank is quickly filling in.

Dosing:
For dosing, I dose 2-part via dosing pumps and magnesium manually. Once every month I adjust my dosing amount according to the system needs. I run a ULNS, so I've found that 15 drops of Brightwell's CoralAmino brings out the best coloration in my corals and prevents the pastels found in starving corals found in some tanks. I also dose 3 drops of lugols each day due to it's potassium content to help maintain blues & purples in my tank. My ATO runs through a kalk reactor to help keep Ca & Alk steady.

Water Quality:
I do 40 gallon water change every 2-3 weeks using RC salt. As far as filtration goes, I run a fuge with a DSB, Chaeto, and LR rubble. My skimmer is a Octopus Extreme 200 upgraded to a Bubble Blaster 3000 pump. I run WM EcoBak, Rowaphos, and Carbon in reactors 24/7.

Lighting:
I run 450w of LED (ReefFiltration Gen2 fixtures) along with 468w of T5. I'm confident that the LEDs can grow coral on their own, but I like having the piece of mind with the T5s producing a broader spectrum. The T5 fixtures houses 12x39w bulbs currently comprised of six ATI Blue+, two ATI Purple+, two UVL SuperActinic, and two Current 10k. Here's my light cycle:
7:00 AM: Actinic T5s ON (Actually two UVL Superactinic & two Blue+)
9:00 AM: LEDs ON
11:30 AM: Daytime T5s ON
1:30 PM: Daytime T5s OFF
4:30 PM: LEDs OFF
7:00 PM: Actinic T5s OFF

Coral Feeding:
I broadcast feed a mix of ReefNutrition Oyster Feast & Coral Frenzy every three days. Once per week I feed my tank with baby brine shrimp. Although this is predominantly for the LPS & fish, some feeder response is noticed in the SPS as well, so I'm assuming that they are feeding on the BBS.

Parameters:
I keep salinity at 1.026 and my temperature range is 79-80 F. Calcium is kept in the neighborhood of 430-450 and I keep my alkalinity at 8 DKH. While this is on the low end of preferred alk levels, I've read that maintaining higher alk levels in an ULNS can be probelmatic. Magnesium is kept between 1300-1350 and pH fluctuates between 8.3-8.5 depending on the time of day. I strive to keep nitrates, nitrites, and ammonia at zero, but many aquarists have noticed improved coloration when maintaining NO3 levels in the 5-10 range (I offset this loss of color by dosing amino acids and through supplemental feeding of my corals). I try to keep phosphates as close to zero as possible and they usually measure between 0 and 0.02 on a Hanna calorimeter.

thanks amazing!!

A question for the experts:

It seems easy enough to keep Ca, Alk and Mag levels stable using a variety of methods that have been discussed quite a bit in this thread. What seems much harder to me is keeping stable nutrient levels...Nitrate and Phosphate. How much do your nutrient levels swing over time? What methods are people having success with in reducing and keeping "stable" nutrient levels in their tanks? what maintenance is required in running your method? Thanks.

I went with the trident method. Prior to that, I used my doser and adjusted according to levels until I reached my goal for content of nutrients

Unlike the big 3 (Alk, Ca, Mg) where the number is the end goal, maybe it's better to look at PO4/NO3 as a side-affect of the actual goal (balanced input & export). Which is a function of tank maturity, quality inputs (food and fish), and exports. It's really that healthy stable balance that's the goal rather than the actual PO4 / NO3 number.

Just a thought, but the 3 big are basic chemistry, but NO3 and PO4 reflect the biology of the tank

What's your tank like?

What's the bio-load like?

Stability is easier to keep on a simpler tank with a smaller bio-load.

Feeding the fish, growing coral (instead of algae) and running a protein skimmer can be enough.

It just takes time. Export needs to match import... sounds simple, right?

After a year, or so, the anoxic bacteria zones in sand and real live rock can easily handle most of the Nitrate - fortunately, they cannot get all of it and it stays low, but not too low. This has gotten hard in recent years with more people choosing to have bare bottom tanks and use dry/dead rock which can take years and years to get fully functional enough to house and maintain a stable population of anoxic bacteria. My tank maintains .1 nitrate which is only detectable using IC testing - is is just "clear" on Salifert.

For phosphate, what most people have forgotten, or do not know, is that aragonite is the key - both your friend and enemy. Aragonite binds massive amounts of phosphate and can act as both a reservoir and a buffer. In a new tank with clean-from-the-ocean aragonite, it can absorb and absorb for months before it becomes full enough to let the tank levels rise a bit. This can mask many maintenance issues where people do not think that they have to change water or have a fuge because their P is low when the reality is that the aragonite is doing the heavy lifting for the hobbyist. In the end, aragonite can only hold so much and the levels do go up in equilibrium with the ambient tank water. ...so for people with established tanks with aragonite that has some phosphate, but not too much, it can buffer at a reasonably low level until water changes, fuge, etc. remove it from the system. In my tank, heavy skimming, reasonable feeding (I do not feed corals for a decade or more), fuge and water changes keep my nitrate at between 1 and 4/5 ppb on Hannah Ultra Low Phosphorous.

Both of these levels are fine for colorful and growing coral.

Just throwing this out there.
I know this is the common, or close to standard, advice given out on forum boards these days. My question is, why??

Why raise the inorganic PO4 level in the open water, where it is accessible by problem causing algae and microbes? If the goal is to provide PO4 to the coral, why not simply feed the coral directly with organically bound PO4, that is not accessible by problem causing algae and microbes??

Peace

This post....mind blown

So glad I found this thread! Loved the pictures and tank specs. I really want to have an sps dominate tank. I've tried a few sps coral, two types of povana and a psammocora, both povanas turned white in a week while the psammocora seems to be doing fine for now, had it for 3 weeks. Tank is 6 months old parameters are:
ph-8.0
Temp-78°F
Sg- 1.025
Cal-400
Alk-8
Nitrate-5ppm-ish
Po4-undetected. Using api for all tests so not the greatest. Starting to think tank just isnt mature enough yet. All other lps have great color and growing.

Great thread.

BTW, if you run a really high pH (if you track it, where does it peak during day and night?) then your corals may be starving for CO2. A sure way to mess up their photosynthetic gear – which would lead to bleaching.

Coral generates CO2 through basic cellular respiration, so I’m not sure it’s possible to starve a coral (or, more specifically, zooxanthellae) of CO2.

Not to mention, a typical environment around a reef tank is going to have more than enough...and maybe even a little too much...CO2 to satisfy they very small amount unicellular photosynthetic organisms would need.

I am very new to all of this aquarium thing. Can someone please tell me how to choose a perfect coral for the kind of fishes i need to keep. Being a beginner i am looking forward to start with a small tank. Please help

you want to look for reef safe fishes. There's a lot of reef safe fish out there. That said, you could put together a stunning FOWLR tank without any corals made up of non-reef safe fish.
