This is an alkalinity conversion chart that shows meq/L, DKH, and CaCO3. It should clear up confusion on how each of them correspond to each other when tested.

This is an interesting chart that shows exactly what natural seawater has in it and at what concentrations.

James,

I'm going to bet you wouldn't expect this from me but I LOVE bluegrass. Awesome video and I'd love to come watch your band sometime!

How big is the patch in your tank? The easiest solution I've found is that if you catch a small patch, cover over them in reef epoxy.

PS: They're bad because they have an incredibly nasty sting.

Here is the thread for the tank in the Austin Pediatric Surgery waiting room:

I apologize there aren't any new pictures updates but that should be remedied shortly.

Mike,

Remind me to tell you what Iodine supplement you should use instead of Lugol's. While lugol's is still effective, it takes a couple of days for it to break down from something poisonous to something usable.

John

No problem Dave, I made Jesse from Elos as Macna 06 show me exactly how to use his tests. I should have their full line of test kits coming soon.

John

Ok so you'll follow the steps below while first shaking both reagent a and C for ~15 seconds to make sure they haven't settled.

-3 mL water

-Add 9 drops part A, swirl for 30 secs

-Add .15 of part 2 (powder, use the smaller end of the spoon) then swirl for 10-15 secs

The liquid at this point should be a light purple. Add one drop of part C and swirl for 10 secs until the liquid in the vial turns blue. Multiply the number of drops used by 100 and you'll have you magnesium.

Hope that helps!

The closest thing to a red tang I think of is the Lavender Tang. Very beautiful little fish!

John

The device you are looking for is called a "Python" and hooks up to the sink and uses that water pressure to start a siphon.

The water in Austin really varies from day to day as we've found. For instance, one of our clients is on a well directly tapped into the Edwards Aquifer. About 2 months ago a HUGE piece of earth fell into the aquifer (we're talking football field sized) and stirred up aeons of stuff. At that point, the incoming TDS was 999+ on the meter. To solve the problem we added several prefilters to the system and waited for the whole thing to calm down.

Recently we learned that all DI resin is not created equal with certain formulas targeting certain molecules and different grades existing throughout. Going to a mixture of DI resins that all have a specific purpose really has improved our quality and eliminated strange diatom blooms. Silicate lab tested still came out high until our addition of filter chambers with specific silicate DI. If any of you are still interested in the topic at hand call up at the store and leave a message and I'd be happy to discuss it with you.

Thanks,

John

PS: 0 TDS doesn't mean perfectly clean water

My only experience is that I see them on my list from time to time and they're EXPENSIVE for such a little fish.

John

We also use algae free magnets both for maintenance and for our clients. One thing very important to mention is never leave your magnet in the tank as things will live and grow in it making it very easy to scratch the tank.

John

Kris,

I think the composition of your reef is really great and see a ton of potential for fine tuning the corals in the 'scape as they grow. The one negative that I can see is that I truly don't like your bulb combo as VHO "white" bulbs of any type always give out a pink glow (this goes for white, actinic white, 6500, all of them).

I would stay with 2 actinic bulbs but move to T5 for the rest of the tank's lighting. An ATI Blue Plus would lend a nice blue look to the eye and color up corals while the ATI Aquablue Special would be a white bulb with the faintest hint of blue.

One of my friends had the same setup as you and retrofitted 4 T5's to balance the look and couldn't be happier with the result.

John

Food for thought...

You could test your RO/DI then your freshly mixed saltwater.

Are those picasso clowns I see Andrew?

Just FYI we also use 1 micron filters on all our RO/DI units. If you think about it, if the 1 micron filter becomes clogged quickly but not the 5 micron, the stuff getting through is hitting your more expensive RO membrane.

Fox just ran another news story on Qua telling how PETA is protesting the treatment of the animals inside. They voiced the same concerns we did about noise, etc. Benny (the manager of Qua) said that the allegations were ridiculous and that they had spent over $500 million dollars on making sure the sharks would be safe (I'd just like to laugh in his face on this one because we went out there).

PETA also said they had reports of at least 3 sharks dying while Qua said only one shark has died and it died in transport. Sigh

The lights look like a good deal for $150 but the skimmer is worthless in my opinion.

John

It should me noted that bryopsis is no laughing matter so do your research before commiting to these corals.

Option 3 is way more likely. Let's hope they lose so much money that no one else is encouraged to do something so irresponsible.

I thought we determined it was the new filter sock? Has it happened since then?

Boring show us pictures from today

Joseph,

Did you get these from [information redacted] ?

John

[information redacted] Purple Passion palythoas for sale for the meeting.

[information redacted]

From [information redacted] you would pay 20.00 per polyp plus 45.00 shipping just to get these new purple palys for them or get a better deal from me!

3 polyps for 60.00

4 polyps for 80.00

6 polyps for 100.00

10 polyps for 150.00

Anyone want to get them after the meeting at Rivercity can come back to my casa to see what I have for sale. I live 1/4 mile away from them.

Water quality will also cause the red streaking in yellow tangs along with improper diet.

James,

Ever seen a full grown chips colony? Search the SPS forum on RC for one, it's incredible.
