Backyard Aquaponics
A place to discuss aquaponics

ah just reread this. thanks for the info. where can i find such a product?

thanks

this is likely gonna be my approach. i'm considering running the baths as growbeds against the back fence. they should look good and take up less space. only problem is with a 2:1 growbed to tank ratio im gonna need like what 100 bathbubs? i guess i don't need to fill the tanks to capacity. i guess i can run low stock rates in the tanks and increase them as i increase the growbeds. thinking about it this seems a logical approach.

i am thinking similar about hireing a bobcat. funny thing is this same guy i got the tanks off owns one. hmmm.

why only half under? why not all the way down? to much earth moving?

i considered this but dont know how to create the growbeds. as suggested i have considered cutting some in half to use as grow beds. just seems like a waste of a tank.

for this reason im leaning toward using the bath tubs as growbeds.

yeah i know i'm addicted. think i need to go to aquaponics anonimous.

good point on the pumps as now doubt these will cost me a small fortune.

first thing i gotta get out to yours and pickup your book.

btw thanks for inspiring my madness.

why cast iron in particular?

i will keep you in mind for sure.

lets just say i was frothing from the mouth for a couple days.

well my logic is i will restore them then the ones i don't need sell for a small profit. i can then use the $ to invest in other aspects of the venture. either way i'm happy.

i guess the saying is nothing ventured nothing gained.

i have lost a lot before through bad investments but lost more through not investing when i had the chance.

the large ponds were used for growing fish, while the bathtubs were used for breeding them, from what i recall.

Why is BF still listed as "Newbie"? Please change this to "Legend" kthx

lucky yes, crazy yes, legend not yet.

i still gotta put this all together first. suddenly finding the tanks has become the easy part. hehe.

EB,Thanks for the correction.Though still have it bad!!!
BF no doubt muz would have the answer, though will start the ball rolling.
Grinding fibreglass is not much fun and without dust extraction I would not suggest doing it in the backyard as the dust will be around for ever.
If there is a lot of mechanical key area(fibre sticking out but well stuck) there are quite a few coatings that will do the job of 'closing' the fibres.
I would go for a elastomeric polyeurathane one pack(paint from the tin)
potable coating (will send mdsa via PM).That way the coating will flex when the tubs flexes and not de-laminate.

Hi Bio-Farmer, Easiest and best way is to use Flow Coat .... If you PM me I will give the info you need to get them done.

How about the sizes of them, and some individual pix of the items so I can see the shape etc Perhaps if they are a good useable size I would like to buy one of each from you to make a mould off for future sales.
I will send them back to you all fixed up when finished. That's if they are a good useable size and shape.

Muzza.

Very nice work BF..! (jealous too). If you are interested in getting rid of a couple once you have restored them please let me know...

Are you on a flat block? Would be nice to have an incline and have gravity do some of the work for you.

Am I right in thinking that fibreglass tanks/tubs like this would need to be supported on their sides if were filled with water above ground, or is it strong enough (given that the fibreglass is a decent thickness)?

cheers

you raise a number of good points i hadnt really considered. thanks for the heads up. good info.
