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.
Seems to me that your nitrate reading is a little too good to be true. What test kit are you using? Is the reading in mg/L nitrate or in mg/L nitrate nitrogen?
Sulfate really isn't an issue - it is actually a major constituent of seawater. If you want to be fussy with magnesium, use a 10:1 MgCL/MgSO4 ratio to keep your chloride and sulfate ions in the same ratio as found in seawater.
Carbonates easily build up at an air-water interface like the one inside the venturi, and it is just a matter of time before the buildup seriously restricts the amount of air going in. I use a short piece of coat hanger wire to knock it out.
Interesting stuff. I didn't like the "sugru isn’t suitable for use in direct or prolonged contact with food" part, and have to wonder why it was necessary for them to state that.
I get that way about some things in the hobby too. But I prefer less open-ended targets. When do you declare success? After you've kept one for 10 years? After you've kept 10 for 10 years each? And, if you succeed at either, will you even know why? The person telling the story I repeated...
Re: goniopora
Here's a story I heard from a well-known aquarist at the MACNA3 cocktail party...
Gonioporas are a great coral for retailers to carry. The hobbyist buys one, it does really really well for six or eight months, and then suddenly dies. The hobbyist blames the loss on something he...
Something Fishy in Northampton PA (out near Lehigh Int'l Airport) is having some Friday only, in-store only deals (http://www.toofishy.com/home.php), including 25% off tanks, stands and canopies, 35% off clams, 50% off one coral, yada, yada...
Premium Aquatics is in the running too with 10% off everything and free shipping with a $75 or more order - http://www.premiumaquatics.com/clearance/turkeysale09.htm.
Anyone have any personal recommendations for powerheads to mix up kalkwasser? I expect they'll all eventually need cleaning, but which ones require cleaning less often?
Champion is running an interesting sale, with up to 20% off if you spend enough. What I find unusual about the sale is that you can get 10% off Tunze, Vortech, Neptune, Digital Aquatics Reefkeepers, and others, where most sellers always stick to the MSRP. Check out...
Please don't tell this to my Yellow Tang. He's been swimming through a daily Lanthanum Phosphate cloud in my sump for a few months. Do you have a link for the story?
I did come across a story about a retailer in Cleveland who stressed a number of tangs in an apparently fish-only holding system...
Boomer,
This is the first time I've seen a reference to using a sub-micron filter to remove the precipitate. I think sand filters can get down to 20 microns, DE down to 2 or 3, and filter bags down to one, but how is sub-micron filtration accomplished?
Thanks,
Bob
I'm not sure where you are located, but look for an Asian food market. There's one near me in East Hanover, a few doors down from Hanover Pet (a.k.a. Aquatic Visions). You can usually get large packages of 50 sheets for 5 or 6 dollars. I recommend getting the smaller packages as I find the nori...
Not sure why you did this, but here's a good reason...
Returning from the weekend at MACNA I found that my old black sea cucumber had pooped sand all over my 3"x5" Alien Eye Chalice and killed off 2/3rds of it.
