http://www.austinreefclub.com/topic/25278-jeepertys-non-build-build-thread/page-4 there are some very simple control profiles you can make for it. it plugs into the VSP port just like you would a dimmable LED. you can control 2 independently from a single vsp port.

I've been making cables for folks and dont have a jebao of my own to test with. does anyone have a long term spare that i can use for testing purposes (until you need it?). I'd be happy to make you a cable in return for your efforts.

I'll take the decorations if they're still available. Sent from my iPhone using Tapatalk - now Free

I didnt ignore it, i stated that to make an accurate comparison, YOU DONT NEED DOSERS! I use them because i want to. You asked a question (why isn't it more popular?) and I answered it. It's a weird niche between value dosing (kalk) and high end dosing (CaRx & 2-part) that no one seems to spend much time in. People tend to keep dosing kalk OR jump straight in to the deep end for high demand corals and not mess around with transition supplements that have limitations.

My dosing pump cost $280. Dollars. However, this is not a necessity for 2-part, it simply allows me more stability and control. For an apples to apples cost comparison, DIY dry 2 part + magnesium can be had at a small fraction of the cost of acetate. A full 2 part system with enough material for 8 gallons of all three parts is 80 dollars. I don't know the exact cost per meq/l for 2-part, but 8 gallons of two part when compared to 1333 mL ($15/250mL = $0.06/mL * $80 = 1,333 mL of acetate) of All in one for the same cost, is really no comparison at all. Back of the napkin, 1,333 mL of acetate would last me a year and a quarter. 8 gallons of 2 part would last many years. Back to my original post, it also allows fine turning, which acetate does not. You get what you get, and if you don't like it you STILL have to adjust with a 2-part component. Per the new Neon Reefer forum literary standard, the link is http://www.reefkeeping.com/joomla/index.php/current-issue/article/44-calcium-reactors-in-out-and-everything-in-between-part-1 As you can see, the line for acetate would advance even more steeply than the red line for B-ionic. Additionally http://www.advancedaquarist.com/2003/2/chemistry As you can see in the second chart, acetate is even more expensive than B-ionic, which is generally accepted as the absolute most expensive way to dose 2 part. So back to my original point, it's not popular because its more expensive, and not able to economically keep up with high demand or large tanks.

i believe i found your answer: http://floridakeys.noaa.gov/permits/lionfish.html It's not about taking the fish, its about the area in which you take them.

or was he?

Kalk only raises Ca and simply helps to maintain Alk not actually raise it. Kalk will raise pH and can help to precept out PO4. But it far more complicated than running Salifert thru the ATO IMO. The bolded statement is not correct. Kalk can and will increase alkalinity, however it does so at a ratio that is directly proportionate to the calcium addition. Consequently, if you desire higher alk than kalk can provide, you will need to use an additional dosing method.

I dose Mg 10 times per day, every day. All i was doing was responding to your question of why it isn't more popular. It's not more popular because there are more precise and economical methods of control (on a per meq/l basis) for large and high demand tanks. I prefaced my previous comment by saying that it would be adequate, and even beneficial for beginners to use on small or low demand tanks.

I've bolded some of the cons to using an all in one method. In short, it's fine for small tanks or low consumption tanks, but if you're doing large SPS dominant, other methods are better suited both from cost and control standpoints. "Calcium acetate is a product that has gotten relatively little publicity despite its apparent ease of use and the commercial availability to aquarists. In some ways it is similar to the combination of limewater and vinegar.16 When dissolved in water (fresh or salt), you have calcium ions and acetate ions. The acetate is rapidly metabolized by tank organisms to form bicarbonate, carbon dioxide, and water: CH3COO- (acetate) + 2 O2 → HCO3- + CO2 + H2O This equation suggests that pH of such tanks may stay near the low end of normal, because of the excess carbon dioxide, but the practical experience of people using calcium acetate suggests that this is not a big concern. Calcium acetate may also facilitate the conversion of nitrate to nitrogen gas (N2)16 in anoxic regions of live sand and rock by providing the carbon source necessary for the process (but this has not been demonstrated one way or the other). The equation below shows the process that could take place: 5 CH3COO- (acetate) + 8 NO3- → 10 CO2 + 4 N2 + 13 OH- + H2O One of the sources of calcium acetate to aquarists is Salifert’s All in One (a product that also contains some strontium, amino acids, and some trace elements). It is a liquid product that can be poured directly into a tank with no immediate concerns about pH. The current version of their commercial product is 250,000-mg/L calcium acetate, so it contains the equivalent of 3,160 meq/L of alkalinity. This products sells in the US for about $31.50/L. Consequently, it costs about $10.00 per thousand meq/L of alkalinity. That price makes it very expensive for a tank with a large demand for calcium and alkalinity, but the zero initial costs make it attractive for small tanks, especially nano-reef tanks. I have no information on the purity of the material, or the exact nature of the “trace elements” in it. Everything in the bottle will be delivered to the tank. It poses no unusual safety concerns. The upper limit to how much calcium and alkalinity can be supplied to a tank in this fashion depends on two factors. If the metabolism of acetate is rapid and the dose is very high, oxygen might be depleted. If the conversion is slow then acetate can build up in the tank (not itself a significant concern except perhaps at very high levels where it might confound an alkalinity test2). Habib Sekha of Salifert has indicated that using the doses recommended on the bottle will not lead to either of these issues being problematic. Overdosing is not expected to be an unusual problem, but if one makes significant additions in this fashion, the alkalinity will take time to show up completely in the tank because the acetate takes time to be metabolized. Consequently, I’d wait a day after adding it to measure alkalinity. Calcium measurement won’t be similarly impacted. Tank salinity will not increase over time using calcium acetate." -RHF Additionally, you still have to dose other things (namely Mg) which IMO makes this not as attractive. Personally, if I have to dose, I'd just as soon dose straight 2 part without relying on microbes to do any conversion.

You're gonna need a new dust filter for your Hoover MaxExtract PressurePro model 60.

I will be over during that two hour period, boxing up everything in richard's tank and cramming it into my tank.

definitely GSP, it will only grow by encroaching, won't drop pods off like bcp.

You'll get a great price ! Unfortunately, you might have some black sedans show up at your door.

So this kind of brings us back around to salinity as a #2, if temperatures don't stabilize.

It's pretty common knowlege that pH and Temp are the two most sensitive issues when dealing w/ Duncans outside of the most basic of basics such as Salinity. Also tis pretty common knowlege that all corals have different needs concerning lighting, water quality, feeding ect..ect...ect... Some are more sensitive to lighting where others are more sensitive to another quality. But for Duncans they are more sensitive in the areas of pH and Temps as compared to other water qualities or flow ect.... Not saying you cant grow them in higher pH and Temps, just what they are most sensitive to. Corals do adapt but flourish at different levels due to different qualities. But I suggest you check it out yourself. You can always learn something new! Right? Just cause you can grow threm in a particular situation doesn't make the science wrong. It just means they could probably do better if conditions were improved. There is science showing that duncans don't do well above 79 degrees? I would love to check out someones dissertation on temperatures affect on aquacultured duncans.

Must be real thin, because the penalties seem pretty stiff.

You could get an AWM to control your frag tank AIs as well
