This is off topic(I do talk abotu fish and plants though) so skip to the next post if it bugs you.

Well, I am very market focused. In general, there is a bottom range that likely will not go down much farther(who wants to rent when it's cheaper to buy?) and slightly above that by 100K or so is my target range.
Most say it'll be summer before the market bottoms, but not sooner than that.

New homes for (ahem fish!) will drop the most(say 15%) and older more stable areas (maybe 5-8%) but you do not want to buy and end up stuck with a loss.

So a short term investment propertery is an extremely bad idea!!!
It's fine if the market is appreciating but that blew up recently and there's a huge inventory that will take years to settle down.

Same with HC in the plant trade, it's still $$$.

But if you are in it for the long haul, you need to live somewhere, you will likely come out ahead. The issue is is it cheaper the rent a nice place you like? Or buy a home because you need more room, do not like where you rent now? We need to live somewhere and pay rent or a mortage etc also.

I'm working with a new mortage company(they need the $$$) and they just brought a lot of Foreclosures and I'll try and get that list and buy from that list. It's like buying proprety wholesale. So I am connected and it pays to be in this largest investment of most folk's life. It really pays to be a smart buyer also. It has to meet a lot criteria before I'll buy. I am pre approved, you can do that right now etc. If you are a DIY person and plan on fixing the place up a lot, then it's a good deal also.

But placement of tanks inside the home is a thing for myself.
I'm very picky about it. I have several ideas and most of tiny tanks will go and I'll just have mostly 20, 40, 80, 120, 135 and 180 gal tanks.
I may interlink them together depending on the floor plan of the place.

They will have auto drain and fill and the tap will run through a carbon filter prior and be heated etc to about 80F.

That part is a must.

Mike,
yeah, the bubble counter has one built in and I also have an aqua medic check valve inline.

Yeah, I had the venturi hooked up with the booster pump and the eheim running at the same time and the Co2 tubing collapsed because it was sucking so much. With just the eheim filter it is just the right amount of flow. I'm surprised people haven't got more excited about the venturis. So far it's my favorite solution between reactors and glass diffusers. I'm going to work with the engineer at mazzie and get recommendations for different eheim models/ flow rates. Hopefully get an article to the AGA. The size of the mist doesn't distract and you don't have to ever clean it like a glass diffuser.

For inline injection from a cannister up to 185 gph the 584-C seems to be appropriatly sized. While the bypass is extraordinary it becomes useful for attenuating draft for fine tuning.

For predrafting an impeller you can go up to a 3/4" application to reduce the velocity as the cavitation will chop the bubbles instead of tearing them from the venturi whilst allowing a greater flow rate.

and for tanked Co2 you will also want to go with the larger fitting to reduce the velocity as it's under pressure. The sleeved cap tubes are for the most part necessary in this application other wise the apherons are quite large.

When using both a diy reactor, and cannister the venturi can be used to purge the waste gas from the reactor and you can run the Co2 directly to the impeller. This was an odd configuration, and I was really disappointed in the froth in the reactor chamber, but upon closer inspection there was an EXTREMELY fine mist being released into the tank. Within minutes the entire tank was bubbling like club soda. This was the most efficient configuration producing Co2 in excess of 35 ppm from a simple yeast reactor.

It's just as well folks didn't rush into it as the sizing of the venturi becomes critical, and most would simply dismiss the results as ineffective. They are Extremely effective, but have to be selected with some care for best results. I have little doubt that one day it will be a common application, and we'll be having a good chuckle over the more arcane reactors we all used in the past. Grtz, Prof M

The cleaning issue, as well as removing another item from the tank seems like a very good alternative. If you compare to ADA diffusers, these are much cheaper, I'm using Rhinox these days, much cheaper and about the same quality. Unless the Venturis get down to less than 20$, and can be used on 100 gph or so, they will have aniche rather than a main stay market.

Still, they have a very good potential and I always wondered why more did not use them before.

At least there's one convert

Nice pics.
Try the harder or thicker tubing and there's no collapsing.
The Clippard tubing is super!!!
Cheap too.

I plan on using that for my entire house.

I think the advantages are:

1.Cleaning- that's a big one
2.Getting yet another item out of the tank without sacrificing the method of diffusion
3. Cost is very reasonable
4. Mist is well dispersed and placement and direction of mist is much easier to achieve

Also, the smaller version you speak of will have a lot of application for powerheads that folks commonly use and also for sump based systems that feed into the return lines.

Take a look at this website Tom:

Piggington's Econo-Almanac Southern California Housing Bubble News and Analysis

Some very good analysis (graphs and all) on the real estate market.

I have purchased 5 houses and resold them later. In every case I made an obscene profit when I waited at least 3 years to sell. The first one I sold in 6 months and had a small loss. The secret is to buy well below the price you see people in that general area paying for houses - that means people are willing and able to pay the higher price you need to make a profit. Then, DIY fixup the place, add things like better kitchens and baths, better windows and doors, landscaping, etc. You get to enjoy the fruits of your labor, and when you sell the place it is worth more than you paid even in a down market. Also, even though obscene profits are possible, don't hold out for an obscenely obscene profit, or you won't sell for as much as if you offered it at a normal obscene profit. I see no reason why this formula won't still work, unless you are buying in San Francisco Bay area or Silicon Valley, where the prices are already well above the surrounding areas.

A good place for an aquarium can only add to the profit. (Just to get back on subject.)

A little update on the venturi. I've noticed that the bubbles may be too small. I was having better success with the glass diffuser in terms of plant pearling. I might setup the 1/4" Mazzei injector Co2 line to get a bigger bubble size. Maybe the smaller bubbles are being absorbed faster? Need to get things to disperse around the tank better, and under the leaves, so I can get that champaign effect out of the plants.

I've wondered how the bubble sizing would effect things.
The larger bubbles would suggest a few things:

More notion of the gas phase and more disturbance of the boundary layer on a plant. Tiny bubbles might not be the best thing oddly.

I think using a DO meter is about the best method to measure the pearling though.

That's a good standard folks cannot argue much with in terms of influencing anything other than growth. Well, some may try

But I think at the end of the day, you and most folks know when the tank is doing better and less algae, more plant growth and what real pearling looks like.

But if you want more confidence, a O2 meter will certainly help.
Even that has an issue with O2 levels since it assumes that all the O2 is dissolving that's produced by the plants.

Clearly its not

Some escapes above.
But that is true for the other gases as well and when comparing things, it'll be relative measures, not absolute.

So say a measure of:
35% increase in O2 with a SE of 4.6%
Versus
46% increase in O2 with a SE of 5.9%

With one vs another mist method is what you can suggest.
So you could say these are significant differences between treatments in the CO2 mist or exposure to air methods.

I have a CAL Labs in line unit sitting here but will not get around to adding till after Feb 8th or so.
