just found a post on Aquaponics on youtube.
And are thinking of giving it a go, i have keep fish 4 mean years but lost them all last year in a 4 day heat wave. sines then i have had the place insulated.
I am geting sick of going to the hydro shop and paying good money 4over price nutrients.I do have a 200L fish tank just sitting there myswell put it to good uses.I gess i have some recuse to do.

I don't particularly like how they have that setup... The surge system isn't going to work well as it currently is built... Basically they're doing an ebb/flow (or flood table) but without a proper flood... Really they should be aiming to fill that table - but the sump/tank they're using is less than the capacity of the table, and the surge is signficantly less... They're using a carlson surge setup, likely they're pumping about 6g into the table - probably at about 1 minute intervals...

I'm eyeballing that table up at about 36-48" x 18" - capacity of likely at least 30g; with a 20g tank underneath... Typically ebb/flow systems are filling completely every 3 hours for 20 mins +/-. See where the divergence lies?

Fish wise - they're way understocked; I was adding kno3 at a fairly significant rate to keep up with 6 small seedlings - with 6 bigger fish in the system... They'll be lucky to keep anything alive with 6 little danios...

Aquaponics seem to be a great setup; I'm doing it myself (look a few threads down for the "aquaponics for fish folk") but I'm doing DWC with a drip... Ebb & flow makes sense on a lot of levels - but stick with what works, not something setup on youtube that doesn't follow standard practices...

The Surge control bucket video or youtube clip has been moved to the video section.

Yes i agree i do not like there setup. but i can see some potential with the surge control bucket it could be modified a larger bucket instead of 2 a smaller pump to slow the hold thing down.I think it would be more ezyer than making a complex control bucket no timers or float switches ,relays and shit that can malfunction. may work better in a ebb&grow system.

You don't need to be complex to run an ebb/flow... Pump and timer (one of the ones without pins - or a decent digital timer) is all you need. Simple setup - tray has an overflow (max water height), and a fill/drain (on the bottom). Have the pump come on - fills tray/table and overflows, when pump turns off - nothing to hold back the drain - table drains out back through the pump... Nothing complicated - very simple no need for relays or float switches...

Surges aren't good for this application... I've played with surges in the aquariums; even there they can be a royal PITA... In hydroponics - it doesn't make sense...

Agree again ebb n flow don't need a control bucket but ebb and grow does.The control buckets on ebb and grow system can be quite complex i just think this could be ezyer and cheaper.

I can do a test will let you know how it goes wish me luck.
