story time :)

so, my previous tank (40B) was setup from the start with the idea of low to no maintenance, and near zero water changes. long story short, that doesn't work on a new tank. it seemed like my lazyness and attempts to automate all the things just came back and bit me in the behind.

i was always fighting "something".
low nutrients, high nutrient, bleaching, browning stn, rtn, zoals closed for weeks, sponge apocalypse, diatom apocalypse, various algae, slacking on siphoning detritus and just letting it build up under the rocks in the dead sports...

with all that experience, i'm going to force myself to do biweekly water changes for the first few months, with as little dosing as possible, depending on stocking and uptake, manual dosing when required to keep things stable.
monthly water changes once things start to stabilize.

currently dosing "a few drops" of NaNO3 per week. one drop daily, or "when i rember"
one drop of Brightwell amino acids, or acropower, depends which bottle i grab.

i will be running skimmerless this time. just one less piece of equipment to worry about or clean and maintain.

current method of filtration consists of an IM filtersock, filled with some cut up pieces of Polyfilter for both mechanical and chemical filtration.
socks seem to last about a week. i ordered many extras, as i feel like i'm going to be too laze to wash them.

i still haven't decided what ATO i'm going to be using.

i try to de weekly tests of what i think is important... and will do a few triton tests per year to make sure i'm testing correctly, and test for all the other things i don't test for myself.

as of today (only tested the "left LPS tank" i'm hoping the other one is close enough to it :)

SG: 34.4 ppt (hanna)
Alk: 9.4 dKh (hanna)
Ca: 418 (hanna)
PO4: 0.061 (hanna ulr)
NO3: in between 2.4 and 5

and i moved two cerith snails and two small hermits into the left LPS tank.

Very nice, I can totally relate to your reasoning of going smaller due to expense, even more, the set of challenges on smaller reefs are perfectly comparable to any big reef out there (Less water, less equilibrium... Or hard to control).

Best of luck!!! :)

so, i don't have a par meter.

this can't be good if i start a post with that :)

but it looks like some, or most of the corals are trying to tell me that they are getting too much light. even on the bottom.

so i dialed the lights down a bit. going from 50% peak power on the uv, violet and blues to 30%
and from 15 to 10% on the white. not using the green and red at all.

a total of 20 watts (as displayed in the app, not measured)
i need to find my kill-a-watt and plug the light into it.

we'll let this run for a week or so and see if things respond better.

the challenges of using lights that were not designed for a nano tank on a 10 gallon :)

So I ordered that uv sterilizer.

Then I thought, 1ml of H2O2 a day isn't going to hurt anything...

My uv sterilizer got delivered today.

And the bloom is gone! Looks like the peroxide took care of it.
too soon!

there was still a little bit of a hazyness to the left tank, compared to the other one, so i ran the UV anyway.

today they are both clear! i'm pleased with my purchase.

it does add some heat to the tank, it's running at 80F now, the one without at 78F.

but it looks like some, or most of the corals are trying to tell me that they are getting too much light. even on the bottom.

so i dialed the lights down a bit. going from 50% peak power on the uv, violet and blues to 30%
and from 15 to 10% on the white. not using the green and red at all.
things are starting to look better.

i moved most of the surviving frags into this one now, to get a good gauge of when i've found this setup's sweet spot, and can start stocking new corals.

i still haven't decided what ATO i'm going to be using.
installed an ATO on the left tank today, if this goes well, i'll setup the same thing on the other one.

decided to try the IM hydrofill titanium.
i liked the idea of conductivity sensors.

i also got the IM ATO pump, but it's surprisingly more powerful than i thought. when usinf it with dosing lines, hooked up into a kamoer tube holder with very small outlets, it sprayed a jet of water into the tank, and splashed all over the place :)

so i hooked up the Toms aqualifter instead. that one barely has enough head and flows nice and slow at this height.

until recently...

when i first got it, september 2018

fast forward to end of june 2019... this was right after the troubles with the 40B, and i moved it into the temp. 5 gallon fluval, right before i went on vacation.

and today, it's looking really nice, and has quadrupled? in size!

That Hydrofill looks amazing! I've struggled with Optical sensors getting cloudy and not working properly. I've also struggled with magnetic sensors getting jammed by Kalk or something, the titanium probe solves all that perfectly. I wish there was a way I could add one to my Apex.

Myself, I've settled on a pressure-based normal level sensor from Avast, it's been foolproof for me in this role. I have an optical one for overfull protection (they have never failed open) then an under full sensor that's mechanical because they typically only fail at the waterline where Kalk turns solid.

I love your tanks as well, I had considered that one and the Cubey for my build, they were the top two contenders. I was hoping to use the light from the Cubey but it turned out that it didn't put out enough Par. It's growing orchards for me now.

AH! yes, the ATO on my very first tank, a Spectrapure LiterMeter III, used a pressure switch too. worked flawlessly, until the day that i dropped the dang thing, and it shattered into many pieces of sharp plastic :)

That's the pump I have on mine! The parastolic pump. I LOVE it!!! I'm sure it won't be an issue for you, but I really struggled with the Aqualifter pumps. My tank was larger and cooled by evaporation so it toped off allot and the aqualifter would wear out. Now I have a chiller.

i wanted something that was low flow. the aqualifter barely makes it, pumping slightly over it's rated head pressure :) i only evaporate around 300-400ml per day per tank. and it's surprisingly quiet, i usually don't hear the pump, but i notice the trickle of water entering the tank :)

i'm going to order the same setup for the other tank, so i can stop the manual top-offs.

Yeah, for you I think it's probably a great choice. Myself I was toping off 2-3 gallons per day and the pumps would burn out or jam up every year or so. It's worth mentioning that my topoff water is in the garage and pulled probably 40 feet to the tank. That failure wouldn't even have been a problem considering the pump cost except they seemed to do it when I was away from the tank.
