Overall, I agree. This is probably NOT a big deal. However, I don't know that I 100% agree with you on the "plasticizers go straight to air" statement. Pthalates belong to a class of chemicals called Semivolatile Organic Compounds, which as a general rule, are only marginally likely (semi, lol) to be apt to directly sublimate from a solid, through the aqueous/dissolved phase and out into the atmosphere. I see pthalates in groundwater regularly. Even though I technically disagree with the statement that they jump right out into the air, I agree that the likelihood of issues are small, and that most people run GAC which would remove it from the water column anyway.

ugghhhh. that sucks. did the ALD ever work prior to the leak?

the mendeley link is broken for me.

dude sweet.

Marine geochemistry is pretty complicated, and when you throw in livestock with a wide variety of specific needs, I would use an abundance of caution. The problem here is even just the lanthanum, that has been used with some success in reef keeping. The problem is the rate at which the phosphate is removed, the fact that it can precipitate out alkalinity, and any other unknown reactions that can affect reef inhabitants. I'm not saying this won't work, I'm saying extensively test it before putting it into use on a closed reef tank system.

This stuff is *not* GFO. It's lanthanum-based. http://www.sepro.com/phoslock/How-Phoslock-Works.aspx Be very, very careful. Lanthanum chloride has been used with varying levels of success in the hobby, but it's one wild-card is the speed that it removes PO4 from the column. I would be wary of off-label use.

An impostor!

You gonna sell a CaRx too to feed that beast ?

It looks great man! Night and day from 6 months to one year in growth and color.

You're like the rick perry of reefs. And before everyone goes rabble rabble politics, I'm talking about this transformation: to

Dogs and cats LIVING in harmony. I may as well change my name too and put up a tidal high nutrient tank.

I don't have any data to back this up, but I'm a big fan of CaRx just on a philosophical level, because it literally dissolves old coral to build new coral. You KNOW that everything they need will be there. You also don't get long term salinity creep like you do with 2-part dosing. WRT to the aquamaxx, i think if you have the ability to put the Rx in the last (read cleanest) chamber of your sump, that your clogging issues should be pretty minimal. if you're looking at this from a budget perspective (CaRx specific), the best bet is a used reactor manifolded to your return pump.

yeah, the peristaltics that are built for continuous use that have enough flow rate for CaRx use are pretty expensive. they can also be noisy. I'm pro aquamaxx for the exact reason you mentioned. i think its probably easier to maintain consistent flow (and by proxy alk/ca) by using a standalone pump vs a manifold. it's probably not enough of a difference to freak out about it, but I also like the idea of being able to apex off the feed pump, something you can't do in a manifolded system.

Seachem salinity is the brand that has the twist lid

Richard L uses a floor based unit with maybe a 1-2 gallon chamber. That's servicing 300-400 gallons in a small detached office space.

I'm an art major

Honest opinion, if a purpose built piece of equipment exists, spend the money on the application specific tool ESPECIALLY if it can kill your tank if it malfunctions. Just my 2 cents.

looks swank seth.

Sorry sold.

aragamidointhisright?

The jackson school of geosciences does turn out geological jedi.

I'll be responding to Master Moede in 2 years (if I pass...)

And somehow I managed to kill mine.
