The NP test 1 time per day currently. The hobbyist sets the time.
Currently the Neptune reagents are sold as single unit similar to the original Trident's launch. It wasn't until later in the release cycle did they offer 6 month kits. I speculate that this will be no different. Neptune needs time to assess the installation base, reagent results, hobbyist test frequency (standard schedule vs standard schedule + manual), and so forth. My guess is that we will see larger kits reducing the price later.
Honesty in reefing if the reagent cost + initial investment seems unacceptable then it isn't for you. Automated testing is a luxury and quality of life improvement, not a necessity as you know. Hanna's eggs for Nitrate and Phosphate are simple to use and when testing both the hobbyist will be done in less than 10 minutes. Nitrate is 7 minute count down, phosphate 3 minute count down, and both 2 minutes to shake and bake. If anyone wants to test less than daily no reason to automate in my opinion.
Edit: when I say honesty in reefing, not for you - it is generally speaking and not specifically you.
Ah... expense is not the issue otherwise I wouldn't run a 4,000L Tank with exotic corals & collector fishes.
My tank & its accessories alone, cost more than half of most people house. Electric Bill is $750+ on 5HP AC alone + food, water change, addictive, that's another $300 more or less. So that's $1,000 on low end, that's more than some people's mortgage already. On summer lone, Electric easily spike to $1,000 just for AC alone.
The Issue is the unnecessary expense. While I enjoy luxury lifestyle, I do not enjoy spending money like an idiot. If there is anyway to save it, I will. If not for anything else, at least for ease of mind cause I wouldn't be feeling like a fool.
I'm the kind of people that will pay $10,000 for an App/Software that I use but I won't pay $12 for any TV Subscriptions cause I can get everything through my Lifetime VIP membership that cost just $199, for a lifetime but pay just once! With the ***** Disney keep push out, they don't deserve my money.
We're Asians... I'm Chinese. In my country, people respect you for being rich but if you don't know how to save, they treat you like a little lost stray puppy. The term "Crazy Rich Asian" while it sounds good to people in the west because they worship wealth... In Asia is different... it literally mean what it says "CRAZY". They think you're "CRAZY", if you're spending like a broken dam, no matter how rich you are.
If you're millionaire but wearing $12 Casio Watch, they will think you're smart. If you wearing a $1.2M watch like Richard Mille, they will think you're an idiot who don't know how to spend money.
A friend of mine got married last year, they both belong to extremely wealthy family, their entire wedding hall decorate by Real Floral that cost over $1.5 million USD for entire Building. According to some news report, they spend roughly 35 Millions on their entire wedding due to their connection to Politicians & Other Elites, so wedding is almost, royalty-like. But how much they spend, I never asked but I did know the Bride's gown is 12 million, made from Italy. Their wedding was indeed, a bit insane, even for me... but it's their money... however... you should see Social Media... 98% of my Country put them on a Blast for being "Wasteful" like spending $1.5M on a flowers that would rot away in 3 days. Every sentence, curse words send to them are center around 3 words "Idiot, Fool & Crazy". Nobody is blessing them, everyone is shaming them. And I'm trying to avoid that "Crazy Rich People" term because I'm neither that rich or crazy.
For example, whenever my relative visiting... they will say how nice my tank is... They love it, they get lost in it. My elders could sit with a beer watching my tank all day long, but when they heard about the price, they looked at me like I got hit in the head by something. They think I'm an Absolute Idiot for spending so much on a Fish Tank.
I used to have a planted tank. When I told them about my pure breed of crystal bee from Taiwan that cost $350 per 1pcs at size of a rice grand, my uncle turned to my Dad and said "You need to get him a brains scan, something is seriously wrong with him".
So... that's my life.
I do have Hanna Checkers, I never used it much because I got used to using Test Kits instead & it's faster than Hanna and I'm often spilled Hanna's power when try to pour it into vial. However, I'm also too busy to keep up with manual testing. Hence, the need to get these auto-tester.
I also got a ReefLab or was it RoboLab? From Reef Kenetic, I think. That cost me $2000 (Tax & Ship). Thinking it was a All-in-one Test. Only to find out it's a Robot. Didn't even bother to open it from the box. It's still new in the box. It's the newest version, I got it around $1200 + delivery + massive tax due to it have needles came with it, so it got registered as Medical Product and since i don't have a medical license, I have to pay a hefty fine to clear it out from custom office.
Testing once a day is quite unnecessary as I've been keeping reef over 12yrs and before all these fancy ***** came out, I tested like twice a year. I only test closely during start up, after I found my range, I just keep a tight schedule and never bother to test anything unless something is off or I'm really free...
I do recommend Feeding Corals & Amino Acid, works insanely, if you can keep Nitrate & PO4 under control and it built almost a True Ecosystem like that I could get away without testing for year at a time. Any algae increase, I just manually dose Ethyl Alcohol 3ml per 100L until it goes away.
Same with Trident... I made it test twice per day but only every 3 days, The combi in the morning and KH once more in evening after light is off. And I was able to find the range that Trident control DOS to work flawlessly with my Octopus Commercial Calcium Reactor CR350. I found a trick in YT about controlling CO2 Solenoid to control Calcium Reactor and it is wonderful. So my DOS were set to a range where it would balancing out with Calcium Reactor at range of 380-390 while working correspondingly with Trident Test.
So testing everyday is Unnecessary. It's not about the money, it's about how you spend it. I don't know how to explain it, so let's just say it's a Culture thing. Or rather it's in my blood and I have the urge to save.
Like the Comedian Jimmy Wu said... we're Chinese won't take pride on spending too much money, we take pride on how much we can save. He said whenever his mom got something new, she would rush to him and say "Guess how much?"... That's also my mom too, they're all the same. We're are all the same.
