hi. ORP has nothing to do with purity. Ask the same guy what is the ORP measurement for a ultrapure water, and see what number he come up with. Then tell him your ORP in your tank, as well as telling him the reading for a ultrapure water with very small amount of toxins like cyanide, and ask...

hi. ORP is more tricky than pH, and most people who cares about ORP usually have the probe permenantly in the tank instead of "dip-stick" operation possible with pH. I don't care about ORP that much, but for some setup, it is controlled by the use of ozone. O3 will increase the ORP because of...

hi. Redox and ORP (oxidation reduction potential) is pretty much interchangeable for laymen. In simple term, it is an electropotential measurement similar to pH that tell you how much a type of ion is present in the solution (salt water). For pH, the ion of interest is proton, while for ORP...

hi. The outlook for the coral is not too good since your tank is so small. Try to see if you can bring the coral back to the LFS for credit, and if not, just take this as a learning experience... Good luck. BTW, your live rocks look great.

Tap! Tap! Tap!...

hi. Rough customers, huh? Even if you have the sign, some of them may not see it and tap the tank anyway. I suggest you to install an accoustic sensor, red warning lights, and a 40 dB alarm. When the alarm got triggered by the sensor (tapping of the glass), the noise and light will make the...

hi. Sounds like you are in good hand, but I just want to say something just in case you happened to use the regulator for flow control. As you had mentioned when you ask the question, put the regular between the reactor and the feeding pump, so that the only thing that goes thru the regulator...

hi. The problem with just using float switch to run your kalkreactor is that you can't control the rate (determine by the water pump in the reservior) in which the kalk are added. This can be dangerous, and not recommended. The first option with timer is much safer, but you still need to get...

hi. Well, you tell me if calcium and carbonate are ionic "residual" (whatever that means :roll: ) or not? Do a search on other related "residual" products like AragaMILK and Liquid Reactor, and see for yourself.

hi. When the e-ballast first came out about three years ago, there were a lot of problems with them. In past year or so, e-ballast technology seem to mature a little, and there are less problems. However, reliability of e-ballast still does not match good old magnetic ballasts that works with...

hi. If they tell you the truth, you probably would have spent less. They did the "right" thing :twisted:

hi. Dan, I don't know if shaman and brandon want to have anything to do with the money portion of it... I don't speak for them, you know.

hi. I throw in $10 with shaman and brandon for trunicate... :) Mike, use one of your dissecting microscope and see if you can tell them apart. Sponge is a lot more simplier than trunicate in cellular structure.

hi. The brown/purple stuffs on top of the sand is cyanobacteria. There are many causes of cyano, and water can be one of them. However, before pointing to the distill water, may I ask you what do you add to the tank beside distill water? (e.g., fish food, phyto, chemical additives.. etc.)...

hi. Alevo and Gonio are closely related. See the following thread: http://reefs.org/phpBB2/viewtopic.php?t ... a&start=20
