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.
Anyone have or know of any issues using Seio or Korilla pumps with classic on-off wavemakers? These pumps are designed differently than Maxi Jets or Mag pumps, and I was wondering if that had any negative impact on long term usage with on-off wavemakers versus usage with variable speed wavemakers.
I have to disagree with the above majority. Every bulk cyanoacrylate gel I've ever bought has turned into a very hard plastic rock before I've finished using it up. I've heard this isn't the case with the IC-Gel, but this kid has already blown enough money searching for the right stuff. I'm...
Here's an interesting slant from the seller of Tunze's currently available on RC:
2 Tunze 6000 Streams with 7095 controller and 2 magnet mounts
I ran these for almost 2 years. They were consistently given vinegar baths and kept in excellent condition. Run silent and are very reliable. Original...
When it was introduced, people on RC took exception to their analysis. The Brightwell claim is that it perfectly matches saltwater. People on RC said it is impossible to test to the level of precision that the claim made, and the apparently bogus claim disappointed a number of Brightwell fans.
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.
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.
