Folks, if you've recently upgraded or renewed your annual club membership but it's still not active, please reach out to the BOD or a moderator. The PayPal system has a slight bug which it doesn't allow it to activate the account on it's own.
Before buying a chiller, you should consider just air-conditioning the room the tank is in. It is cheaper, and it will keep both the tank and you cooler.
Buying any specimens (inverts or fish) from a photo can be a little iffy. What are your assurances that the photo hasn't been Photoshopped? What are your assurances that the lighting the photo was taken with is the same lighting that you have? Caveat emptor...
Length (in inches) x Width (in inches) x Height (in inches) / 231 = gross gallons
48x18x24/231=89.766
Tanks are usually measured with their outside dimensions, so the rated size is not what they can hold. In this example the amount of water it can actually hold is probably closer to...
I don't see any downside. Maybe they don't know that sulfur is a major element in saltwater. I use a PhosBan reactor filled with CaribSea Geo-Marine Araganite as a second chamber to deacidify the water coming out of the first chamber. I don't think carbon would work to deacidify the output.
Thanks for the info. I had to pull a very large Desjardins Tang from my show tank (aggression issues), and the valonia has become noticeable in his absence.
I can't quite figure out the modus operandi of this filter, based on the description at http://aquaripure.com/Products.htm#Nitrate%20Filters . They seem to poo-poo sulfur denitrators, but I built my own sulfur denitrator and I am too pleased with it to consider using anything else.
It uses a reverse osmosis membrane. Quoting from Wikipedia: "It works by using pressure to force a solution through a membrane, retaining the solute on one side and allowing the pure solvent to pass to the other side. This is the reverse of the normal osmosis process, which is the natural...
Your description of the unit indicates two kinds of carbon and some small micron filtration. I've never heard of carbon filtration removing either nitrates or phosphates from water. If it did, we would all be filtering our tank water with it, wouldn't we?
I QT my fish for months before putting them in my main tank. (I like to spread around the aggression by adding a few new fish at a time.) I'm not as conscientious with corals...
That is why I wasn't interested in one. Seems like you need to add on a separate device utilizing a phosphate removing compound in order to handle PO4 issues.
