CoralVue KH Guardian Pro Alkalinity Controller Thread

[FullBoreReefer]

Kinda pricey, just to try. I'll keep watching for a price drop, competition, or the used ones when some realize they spent to much for it...HAHA

I travel quite a bit and being able to confirm alkalinity from my phone app is cheap insurance and peace of mind.

If I had a buck for every time something was going to 'revolutionize' the hobby, well, I'd have a few more bucks :lol: at least. Even though it's reagent-based, rather than a probe, I'd still be reluctant to dose automatically. Wonder how/if CaRx control could be achieved?

 

[soulpatch]

I don't need it to control other then potentially kill outlet running my calrx feed pump and solenoid. I am more interested in knowing as my levels chang as things brite and I need to adjust accordingly on my calrx. Sure I could test and I likely would at first but to have that one mess thing I have to do other then enjoy my tank is awesome

I have the KHG pro and got it when it first came out at a reduce price. Although I haven't set it up yet. Still waiting to fill my tank, I read a massive thread on another popular reef forum and there is plenty of good reviews on the KHG. It's very consistent test after test so I'm excited to put it to work once my tank is up and running.

I believe it will be compatible with apex soon and they're also working on a way to be able to control your carx if I remember correctly.

What's the cost of reagent? And based on what I read, the controller has to run a test at a minimal every five hours and as often as two to three hours.

$35, minimum of every four hours. Reagent should last three to four months at testings of every four hours.

Also take into consideration that you can tune the testing schedule to your liking. A daily test is what I'd be most interested in.

From coralvue site:
Each pack of concentrated KH reagent shall be diluted with 1500 ml of RODI or Distilled water. Keep the error in +/-1 ml of water. Each concentrated reagent pack can be used for about 45 days if the KH Guardian is set to performs a test every four hours with a consumption of 4 grams of solution.

Mind you that is a monitor and doser. They have the monitor only version out soon for $600 and it has apex compatibility via their AIM module. It was shown at reefapalooza and looks like a solid piece of equipment.

I will probably grab one as 600 is reasonable and will lt me keep my calrx in tune as my demand changes in the tank with growth and frags.


Neptune and others would have made a ton but they are all sitting on their behinds. The fact that coralvue will integrate with an apex with the additional module for a "fair" price makes it almost a no brainer as opposed to waiting an additional year for the others to release.

if this is only monitor there isn't any real benefit of having such an equipment unless you are always out of town or something. but if you are always away, why keep a reef tank? the whole purpose of this device is to help you keep fluctuation to a minimum and without a doser, it is not possible to do that.

 

[soulpatch]

Yes to keep things stable. I run a calc reactor. As media exhausts, corals grow, new additions, auto water changer uptake, and more all cause fluctuations to my alk levels. I am always home for most part but that doesn't mean I want to be constantly testing. To keep things in check with my tank this auto tester allows me to enjoy the tank more and work on other things.

Anyone with an update?
I saw a posting that ph probe needs to be replace every 3-6 mo?
Wondering if that the case with all alk units

 

[soulpatch]

Replaced or calibrated? I have to calibrate mine about every 6 months

For those who havent already looked it up, the KHG costs $1270. I will definitely be waiting to see what comes to market at that price. I think they made a mistake here. They got greedy knowing they are the only item on the market. Had they made the price reasonable, they would sell 2-3x as many and have a much better foothold on the market. Now they will have most folks waiting on the competitors to comes to market.

I am personally waiting on Jonas's Alkatronic. This is a guy who did this as a DIY project and appears to have some amazing accuracy, and it integrates with your Apex to serve as safety to primary dosing method (Solenoid for CaRx etc). It will apparently also dose liquid Bicarbonate if needed in case of significant drop as a backup to your other gear.

This is an exciting time in reefing, as others have noted, keeping your kh solid is THE number one thing to keep SPS. Nearly every one of my problems with SPS was a result of a drop in Kh or an overdose of Kh. All other parameters can be adjusted easily and slowly to keep things in good shape, where if your alk dips low or high for an extended period...you can say good bye to your SPS.

I kind of agree on the issue of pricing . Spare a thought to reefer who are residing in a country where the exchange rate is lower . We might need a lower cost solution and I bet there would be a chinese company copying that design and selling it at a quarter of the price .

Coralvue has the price adjusted and now come with AIM some more

 

[soulpatch]

its nice to see the competition hitting the market driving the prices down to more reasonable amounts. I am guessing when Trident comes out this fall that prices across the board will plummet as you will have a big player testing 3 values for what these guys are charging for 1....

I am still holding off till they drop a bit more and see some gains in the regent costs as well.

Guys i have 2 questions regarding the Guardian
1. what happens in case of power outage?
a. does it test missed test after restoring power
b. sits idle till next test time

2. can you set your own schedule time for testing?
thank you

Guys i have 2 questions regarding the Guardian
1. what happens in case of power outage? Just like anything else, it simply turns off. Nothing dramatic happens.
a. does it test missed test after restoring power. Testing time will just be reset. I.e if you set it to test every four hours, it will count down once power is restored and test within four hours.
b. sits idle till next test time

2. can you set your own schedule time for testing?
thank you. You can only stretch out the testing to a max of four hours.

 

[Dr. Reef]

ok so what i was thinking is possible.
i dont want 6 tests per day. i was looking at more like 3 per day. which is not possible through the guardian itself. but there is a way.
i was thinking to plug the unit into apex outlet and program it to come on say at 8pm so it will conduct a test at 12am(mid night) then have it come on again at 4am to do a test at 8am and finally come on at noon to conduct a test a 4pm.
you think this will work?

I don't see why it wouldn't work and I've thought about doing this myself. However the constant cycling on and off might be harsh on the internal hardware and the reagent won't last forever.

 

[biecacka]

My question is for those of us who dont dose but use CaRx how does this adjust our dkh level?
