hiatt method

[SuperDragon]

Yeah, a couple months really isn't going to convince someone with a full blown reef display that this is something they should switch to. Neither is the fact that a LFS (essentially a big holding facility) is using it. I need to see established coral tanks using it for a while.....or is this just for FO tanks?

If your fish tank isn't broken I wouldn't fix it.
The system is for someone who wants to setup a new tank and not have to wait or someone that is having trouble with their system.
Large fish wholesalers tend to have problems with nitrates because of the large volume of fish and corals they carry. The high fish load and waste poses a threat to the corals. Therefore, it is advantageous for wholesalers to sell, sell, sell or they will lose profit. Otherwise, they throw the bleaching corals in to the potluck bin/tank for cheap.
The system can be adapted for fish only (full carbon) and coral tanks (less carbon) according to the simple formula.
Ca, Mg, trace elements, and pH can be manually adjusted or use pH rock ~ calcium reactor media.

Please keep the questions coming.

Interesting. So you only change out the carbon every 3-5 years? That's kinda amazing.

Not really amazing if you think about it. Tri-based carbon is made of Organic carbon, Inorganic carbon, and a third carbon. I believe the bacteria use the organic carbon to reduce nitrates to N2 gas, as I understand it to complete the aerobic nitrogen cycle, they will also grow on the carbon.

1 lb of carbon surface area is 1150m2/gram or 0.2 miles2 for bacteria to grow on.

Honestly, how much money is upkeep have to change out the carbon every 3-5 years (if cared for properly, by rinsing or backflushing the canister once a month). Some people like the idea of chemical and biological filtration so they change their carbon earlier.

The inventor is a scientist and very good one that carries many products.

my brother's nano has been up for awhile and he threw that tank into a "risk" dumping it into the hiatt (which could ahve killed everything). but then again, its still up and running with amazing growth, check his tank thread.

Dave, I will offer you the stuff to setup a 12 to 20g n/c if you provide the tank and large canister filter.

You offering for free? 'Cause I have a good canister filter and a 24 aquapod with an algae problem, and test kits.

So if you want someone to test it impartialy, I can do that.

i think free to mr dave bc he is skeptical about spending that much on his tank, but think of the money u will get back by selling your skimmer

I'm still on the hunt for a large canister filter.

I got burned pretty bad on the one I picked up. Craigs list will probably get me a bit more than sdcheaps

What are you looking for anthony? What size?

I see. The carbon is not actually removing organics for 5 years through adsorption. Rather it's just providing a carbon source for bacteria to reduce organics?

Yes, we have several good scientists on this site too. Some even hold their own patents as well

The bigger the better.

Like a fluval 304 or way bigger. If you need something way bigger, you could consider building your own.

Well I got a 205 and Richie is telling me that it is just too small and it will affect my nitrates.

How can I build my own?

Let me search for some simple DIY instructions. But basically it's just like making an over-the-rim closed loop with a large pipe to hold the media. I know people have done it nicely using RO/DI cannisters. Let me look really quickly.

Here's a start. You can easily imagine how you could add multiple RO cannisters in series to hold a tremendous amount of carbon.

But typically I see so many used fluvals in the for sale section. That might be your best bet.

Thanks, that is VERY helpful.

This is how to build your own from local hardware store parts. (lots of work)
