    Ocean coral reefs gone in 40 years??

    The truth is that the median age of a coral on the reef is around 4 years. It doesn't take centuries to grow most corals. As you know from observing your own tank. Of course, there are certain types that can live to be that old, and take time to become massive. But most are much quicker...

    Ocean coral reefs gone in 40 years??

    The composition of existing reefs may change, with organisms liking the new conditions taking over, and existing ones moving to where they are now better suited. No way will the reefs just dissapear. That is typical alarmist reporting designed to catch your eye.

    Help!!

    I would ditch all bioballs anywhere. Is it possible that the media in the calcium reactor is releasing phosphates? Harvesting the Valonia is key to solving the problem. Keep pulling it out, and eventually it will crash.

    ?Kalkwasser dosing recommendations?

    Limewater (kalk) is a balanced additive, meaning that adds ca and alk to your water in roughly the same proportions that they get used up. Depending on the concentration of limewater you are adding and the amount of evaporation that you have in your system, it will slowly raise your ca and alk...

    A little off topic, but I've been thinking lately about the whole denitrification thing and not having a DSB. I have a 10 gallon nano, so could not use a DSB if I wanted to. I have a 1" bed of Aragonite, and high quality LR. I know that my tank is quite capable of denitrification, because just...

    Where can I buy pickling lime?

    I looked in Wal Mart to no avail. This may sound dumb, but what section did you find it in?

    NP. Good luck, I'm sure you'll be fine.

    I don't know about recycling an old DSB. From what I understand, they suck up a lot of undesireable compounds that may cause trouble even if you rinse. It's almost impossible to get a bucket of sand to run clear when you clean it, if you know what I mean. Why start a new tank with a...

    Is my candy cane RTNing???

    It doesn't look in danger to me. They will do that for a day or two from time to time. Mine looks terrible when it does that. One thing that I would look at is your alkalinity. You want to keep it between 10 and 14 dKH, or 3-4 Meq/L. Also, they like pretty still water. High currents will...

    I don't like the idea of bare bottom, because I like to have a lot of nice scavengers that like to live in the substrate. I personally use about 1" of aragonite substrate. It's coarse enough that it doesn't float around, but finer than crushed coral which is a dirt trap. My current tank is a...

    That's a first. An escape artist clam.

    Is Phytoplankton a necessity addition to a reef tank?

    One thing I can't stand is when 'the rules for the road' tell us to do something that there is no real proof of benefit. In the case of Phyto, there are a lot of theories about how it could, theoretically, benefit. But when it comes to practical usage, there is no real difference between using...

    What do I do about water Hardness???

    Sea water is supposed to be very hard. The object is usually to shove as much calcium as you can into the water for the corals to use. Hardness is not something that we test for on a reef tank. I think you may be trying to bring over something from fresh water aquaria keeping that has no...

    weird halimeda behavior?

    I would guess that your calcium got too low. Halmedia suck calcium like a vampire sucks blood. (Oooo...Graphic....) Most people don't like it for that reason. Have you checked your levels lately?

    why are my level going back up?

    I can't say if it's too much, but it's significant. The real slow addition usually pertains to adding fish.

    ID Please

    Thanks. I need a way to shorten NaH2O. It takes too long to think. Like I'm in chemistry class. I could call you nah, or h20, or sodium, or water or kalkperson or lady or 'hey you' or bubba. I'll think about it.
