That's a nice set up. Do share more pics. Any issues with the skimmer performance as the water level in the sump varies (bcos there is no panel)

For water flow volume (strength), the Nero is between MP10 & MP40 based on the spec sheet. Diameter of the Nero is 2.8". Its quite close to that of the MP40 (3"). Flow is quite wide. Took a short video of just the Nero5 turned on. All the other wavemakers are off. Can see its quite powerful. Able to push water all the way to the other side of the 5ft tank. Personally I like a lot of flow in the tank, and have rock-scape limitations.....hence the multiple wavamakers. Set up yours yet?

Good to see fellow Apex users. I'm keen to learn how others are using it & always on a lookout for innovative ideas. BTW, what modules are you planning to get?

Very often, hard plumbing increase sound as the vibration cannot be dissipated. You can place the pump on a rubber mat if it does not come with rubber feet. Else, connect to the pipes with a silicon hose. Sample pic from internet. If its not a new pump, the sound could be coming from worn out bushings or unbalanced impeller.

My compressor didn't cool properly late Saturday night. Took 1.5hrs to chill 1degC instead of the usual 30min. The pipe froze as well. A reefer explained this is a tell tale sign of insufficient coolant. I contacted a few service people commonly referred to in the reefing circles but none could make it on Sunday. Fortunately, I googled & found a serviceman who could come by on Sunday morning. That night, the living room air con was turned on & some bags of ice placed in the sump. 5 min task to top up the gas & its all resolved. Many thanks to the reefers who offered to loan me a backup chiller or contacts for air con service. Just got a new roll of Clarisea fleece on standby. Last change was 29th July => 2 months 9 days to date. And still have ~1/4 roll left. The roll should last about 3 months or slightly more Very convenient indeed.

Close up of the Nero5's thick/sturdy ceramic shaft Back to my other wavemaker.... took it out for much needed washing Vinegar soak All clean. My clam moved around & touched the max mini anemone rock. And now the anemone's have decided to latch onto the clam

Nice collection of corals

PM or whatsapp me if you need more info

Ha... well said. The reliability of the local/cloud connection is very good, just like for their Hydra lights. With 1 button on the Nero control, the essential controls are : Feed mode. Press 2-5 sec Off. Press 6+ sec

Comes with a clip holder This is the curved surface. Particularly like the Pulse mode so that the corals are not battered with a constant flow. Didn't realize it until I was just setting it up - just how easy it'll be to remove the pump in future for cleaning. The wet side can easily be removed, leaving the magnets in place Nicely designed for maintenance.

Needed more flow on the right side of the tank with the corals growing over the months & blocking flow initiating from the left wavemakers. Trying the AI Nero 5. It does live up to the hype seen in the recent online videos. Physical installation + app setup took 5min. There are 2 magnets. The curved one inside the tank. The curved profile allows the wavemaker to be angled a little Magnet - the one with AI logo outside the tank facing outwards. Same app as the Hydra lights. Super easy to use app

I'm dosing 20ml per week with Nyos active elements. Approx 5ml on alternate days.

I'm using a calcium reactor running around 20hrs per day. Based on rough calculations, the Ca & KH contribution by the calcium reactor is as shown below. I don't have the number for Mg.

If i'm not wrong, corals turning green either mean too little light or excessive iron. Sent your water for ICP testing?

Quite pleased with the results from the Nyos active elements. It looks like it really addressed the some element deficiencies. I had some casualties previously, especially those that are shaded. Seems to be stopping. Seems to look better 1.5 weeks later. Need to continue monitoring. Cost comparison : For Red Sea elements ABCD, (10ml of each of the 4 bottles per day), total dosing cost ~ $11 per week. For Nyos active elements (5ml of each of the 3 bottles on alternate days ~ 20ml/wk), total dosing cost works out to ~ $5.60 per week The bottom half of this red stag was bone white & no PE on the white parts - from being shaded previously. The green appeared which subsequently started to change change to red. Better PE from this recovering monti This one too. Hosting for a reefer. Capitata. From a reefer

Plan to pass some back to the reefer who gave me this stag frag when I first started this tank.

Must remember to open new bottle of kalkwasser carefully. Crazy mess This dose of kalk paste should kill the aiptasia. The magnetic probe holder is quite handy for letting new max mini anemones rest & adhere onto a rock.

So organised Battery backup next?

According to Seachem FAQ, "Prime will bind ammonia, nitrite, and nitrate for 24-48 hours. At which point, if they are still present, will be released." This gives one sufficient time to take action like water change or to remove the livestock.

Actually there are many reefers who have much larger & impressively nice stag colonies. Some even need 2 hands to hold it

Frag & re locate. This (stag?) is shadowing too many corals. Arrgh... anemone split & moved to an 'illegal' spot

Got my ICP test results back. Firstly, Aluminum has dropped 85% since the last test done in Feb. Possibly contributed by the Continuum Heavy Metal resin? And more probably because I took out as many metal clips (RODI fittings) that were in the system. Its still out of specs but i don't think its an issue. Surprised to see low levels of Lithium, Molybdenum, Strontium & Boron even though I've been doing ~12% water change weekly + dosing 10ml Red Sea elements (ABCD) daily. Switched to Nyos elements. https://reefmarketsg.com.sg/product/nyos-active-elements-250ml/ https://reefmarketsg.com.sg/product/nyos-active-strontium-250ml/ https://reefmarketsg.com.sg/product/nyos-active-iodine-250ml/ Can see a significant change in KH take up rate the next day -> possibly the deficiency is finally addressed & corals are 'growing' better now. Time to re-tune the CR. Some corals seem to have brightened up.

Thanks The new Alkatronic firmware update is good. Its now able to access the unit's setting via the cloud (instead of solely using mobile phone app). It also has "fast mode' which uses a different algorithm to dose KH when it low. Fast mode is to be used for heavily stocked SPS tank. Algorithm info : Normal Mode (=Fast Mode Disabled): • If the difference of dKH and low reference value > 0.14, then the half dose of lacking alkalinity is dosed. • If the difference of dKH and low reference value <= 0.14, then the whole dose of lacking alkalinity is dosed. • If the difference of dKH and low reference value >= 0.6, then Alkatronic will never dose more than 0.35 dKH at same time. Fast Mode: • In ”Fast Mode” it will always dose the whole amount of lacking alkalinity. • If the difference of dKH and low reference value >= 0.6, then Alkatronic will never dose more than 0.7dKH at same time.

Lovely tank! For your UV filtration, how many watts? How many hours per day or 24/7?

Gets bullied a little by the yellow tangs but generally doing OK. Just took this vid
