I use either Crystal Sea Marinemix or Instant Ocean, which ever is cheapest at the time.

Any reason why the Tunze you're looking at isn't controllable? The comparison is odd as the Vortechs are all controllable. I think the least expensive controllable Tunze is the 6055.

I haven't used the Salifert Nitrate kit, and when I checked their instructions I was surprised to find they can test down to .02 ppm. I've always tried for less than 10 ppm (Randy Holmes-Farley's recommendation) and I'm pleased when I get it less than 5 ppm. Good luck getting it to 0 ppm.

I've got a Hach 890 and a LaMotte Smart2. Boomer has some issues with the Hach nitrate test procedure. I don't know his considerations on the LaMotte procedure. I've been happy with both. Some day I'll get around to testing them against a standard nitrate solution.

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.

SWITCH420, Is the 1 ml per 25 gal of your 1:100 solution dosed daily? Thanks, Bob

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.

I think the winner is $41.99 for a 3000 at Aquatic Technology (http://www.aquatictech.com/).

What's the best point & shoot camera for taking tank macro shots? I'm new to this forum so any links to existing threads would be appreciated...

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.

You might consider TB Aquatics instead, as they are one of our sponsors: http://www.tbaquatics.com/shop/.

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...

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...
