A-b Or C For Green Water Tank Options

[wombatt]

I'm having a custom clear acrylic tank made for my indoor green water setup. Wanted to get some advice and recomendations from the bros here to the sizes i'm thinking about.

A - 98"L x 35"W x 18"H = 270 us gal. = 1022 liters

B - 72"L x 36"W x 18"H = 202 us gal. = 765 liters

C - 72"L x 20"W x 20"H = 125 us gal. = 473 liters

I know the obvious would be "A" bigger is always better. But I don't know if changing 1022 liters every 5 - 10 days is going to be a big chore and a long one too, would like to hear some feed back on that too. "B" seems to be a nice compromise. Problem with "C" I think is that if I get more fish then I'm out of room. Planning on having about 100 liters per fish or lets say maximun of 6 fish in A, B and C. Thanks again all!

one of each

i'm not so sure if the electricity bill is a concern to you, as lighting up 1ton of water can be very expensive to me.

I know CyberET Tyring not to think about that right now. Hey if its all sucessful in the end and having nice plumb fishes, it'll be worth it.

[CyberET]

if thats the case. go for the largest one.

have a 100~200 litre tub to hold the fishes and green water for seeding back.

and with larger volumes, you have to see and judge how long before you need to change.

a 400l tub takes me about 1hr to drain and top up. so i'm estimating it'll take about 2hours to complete your drain & top up.

you may wanna add a drainage hole like how top_view_ranchu did for his tubs, it'll aid in draining the water fast, but structure strength and leaks have to be factored in.

Wow CyberET Thanks for the heads up on the time it takes to drain and fill up. I think I'll go with option B right in the middle should be a good compromise for now. Now for the upcomming shock after I'll see the quote on the tank I'll be sure to post pics and step by step photos till the sucessful brew of my first batch of indoor green water.

the main waiting time is for the water the fill up.. no matter how fast i can drain, its the darn water pressure

do post pictures, it'll be interesting to see how it works out for indoor green water on a larger scale

Why do you prefer setting-up at indoor greenwater tub? What are your constrains?

[mountain]

with a larger the volumn, the amount of supplementary components also increase substaintially. i.e. Salt, Anti-chlorine etc etc etc
but as yourself and ET mentioned, time is the most important. Because inbetween your water change, your fish would be house in another tank/pail. If its small there is less water less air which will cause more stress.

funny ... i still see the word "brew" and not cultivate ...

anyway, wombatt, would you mind telling us where in USA u are in and the tap water parameters before you start working on the setup. Municipal water with water tower or ground water ?

Hi Matrix,

I'm in Sunnyvale Ca. its basically in the San Francisco Bay Area about 30 minutes south of San Francisco.
I'll be using municipal water and will actually check on the parameters soon. I was going to use RODI water cause I have the setup left over from my reef tank. But it does 75 gal. per day max. Then I got to find another storage tank to house at least 200 us gals of water just for this tank. And from reading up on Ro water I realized that its probably not that necessary after all. Yes cultivate sounds more appropriate ) .

Ahhh ... silicon valley. I am afraid you might use RO water. I know RO will have problem cultivating the algae. But without RO, the water should be rather hard. Do check for chloramines as your water dept should be using quite intensively.

Well ... give it a try.

Hi Matrix,

Just found this on the City of Sunnyvales website. Its there 2005 water quality report. I will start to make some sense out of all this info. Right now its a foreign lanquage to me. Here are some basic parameters I was able to make out. So I quess I get water from two different sources as follows:

PH - 7.6 / 8.9 ppm

Hardness - 56 / 109 ppm

Alkalinity - 54 / 89 ppm

Chloride - 9 / 55 ppm
