    U.S. mail order shop

    I'll head to St Louis a few days after Christmas, then back to the grindstone here in Hong Kong in time for the new year. It's good to know there are little reefs everywhere, even thousands of miles away from the ocean! Bruce

    U.S. mail order shop

    I will be in Hawaii and then Greenville, South Carolina, then drive from Greenville to Cincinnati for Christmas and then St Louis. So I might be passing your house, Nikki, on the I-74 and I-70! Wish I could bring you a frag from Hong Kong, but it probably wouldn't make it. :-)

    U.S. mail order shop

    Hi guys I will be back in the Midwest for Christmas and want to order some stuff -- one of those blue refractometers, some Salifert test kits and a kalkwassser doser. Where should I order from? Perhaps from a sponsor of Reef Frontiers? Thanks! Bruce in Hong Kong

    Help! Peeling acros

    I just got home from work and looked again. A few branches are white halfway down, and some of the branches are just white near the tips. Where the white part ends there is a distinct change to the colored part -- not gradual. That said, I looked more closely and I'm not sure, but I think the...

    Help! Peeling acros

    Thanks, Nikki. That sounds more serious than I thought it was. I have never had coral die on me before. I noticed the spike in salinity only an hour after it happened, so I brought it down suddenly too. Maybe I shouldn't have done that. I am using Sera glass hydrometers that were...

    Help! Peeling acros

    The acropora in my tank are peeling in patches (not uniformly) and turning white (about 20% of surface area over the last five days). There are two colonies -- one pink and one tan with blue tips. Is there anything else I can do to test or adjust or should I leave well enough alone? Any advice...

    Does everyone really have 10x-20x flow?

    I totally agree on your points on the importance of having flow. I did mean to measure every point in the tank, actually, or at least the parts that matter. The purpose would not so much be to simulate nature, as to have a standard measurement. Now we can say that, in an aquarium, a species...

    Does everyone really have 10x-20x flow?

    For all the devotion I see here, we might as well be giving them massages... and sending them on spa holidays in Bali. ;-) Clayton, know what you mean. Once I had a powerhead flow being deflected by a rock and a tang got pinned and died. I still think it would be more useful to measure flow in...

    Does everyone really have 10x-20x flow?

    That is cool! The ones I removed are also Tunze variable rate pumps. I'll think about putting them back to see what happens. After years of adding more and more equipment, I am now trying to simplify to get back to basics and reduce maintenance for my new tank, but maybe I have gone too far...

    Does everyone really have 10x-20x flow?

    That's what I do too. Last month, I was really stoked to come across a completely submersible hand-held vacuum. (The shop clerk probably thought I was crazy I looked so happy.) So now I turn off the pumps, blow things around with a powerhead, and suck out the piles of heavier gunk from the...

    Does everyone really have 10x-20x flow?

    Interesting. I guess it would be much more useful to look at the turnover of the aquarium through the sump or other filtration system (useful to know for filtration). Then directly measure the localized flow in different parts of the aquarium with a sea current meter (useful for getting the...

    Does everyone really have 10x-20x flow?

    I'm not sure I get how this works. How do you calculate the number of times? I guess it would not be physically possible that you just account for the volume of water that goes through the mechanical filtration system. So do you add the volume that goes through the power heads? If power heads...

    Surge Tanks

    They have beautiful surge tanks at Waikiki Aquarium. They are outdoors and for lighting they use, well, the sun. See http://www.waquarium.org/vt/coralfarm/coralfarm.html.

    Statues in saltwater tank - what problems posed?

    I have some grey concrete bricks in my sump. Soaked them in tap water for a week with a few water changes when dust came out. Then I put them in a bucket of aquarium water. There was no significant change in pH, phosphates, calcium or alkalinity.

    Does everyone really have 10x-20x flow?

    Wow that sounds like one high-energy tank. I'm a scuba instructor and have seen quite a few reef tops over the years. I can't say that the ones in five knot current or in a surge zone are any more beautiful than the ones with 0.5 knots. But that said, one knot is 20 inches per second, which I...

    Does everyone really have 10x-20x flow?

    I've been keeping reef tanks for eight years and just found this site recently. It's great! But some of the information is making me doubt my reef tank husbandry! For example, the consensus recommendation for a good rate of water flow in a reef aquarium seems to be 10 or even 20 times or more...

    help pls 'South Africa'

    Samier: I came across a South African site, sareefkeeping.com, with an active membership and forum. It seems like a good place to find some local resources, expertise and friends to supplement the information from this site. Good luck with your new hobby!

    Prodac Ocean Reef salt?

    Thanks, Nikki. It's cool that bits of our Indo-Pacific reefs end up in places like Indiana and South Africa! Calcium and alkalinity are good. Didn't test magnesium. I've been using the same salt for eight years. This new one really does dissolve well with very little sediment. But guess I'll...

    Prodac Ocean Reef salt?

    Has anyone had any experience with this brand of salt from Italy, especially any bad experiences? It was recommended by my LFS in Hong Kong. It dissolves quickly and my coral seems to like it fine, but when I Googled it, it seems to only be popular in Italy and South Africa.
