Gentelman, I have just built a small tank for my son's school science project, is'nt it strange how much we learn when our kids have projects, anyways back on subject, from the pics posted here the members got great results, mine were somewhat lacking, and the washing soda would seperate and go to the bottom after 5-6 hours, its cold up here in canada but the water did not freeze. would the cold effect the results and should this be do in the warmer months, i am intending on building a 200gal tank but am having second thoughts as per the first results. thanks all

i have a 100+ Gallon tank and i used a box of regular baking soda with Great results ... how ever i found you need to mix the heck out of it .... i filled my tank in the summer and ran it all summer on the same soda and water i just had to top it up once and a while i did find that the water must be warmer or else the soda wont mix in so try warmer water

Yes, warmer water will hold more of the soda in solution. There are two things that affect how well something dissolves and stays dissolved.: water temperature and agitation (stirring). If you mix the solution thoroughly and then start the current flowing, the water should heat up from the process and keep the soda in solution better.

I haven't used mine in really cold conditions, but can tell you that it works when it's cool.  Last fall I used it up until the first of November and the water temp must have been between 5 and 10c. It did seem to slow down a bit but continued to work. My tank is a plastic 45gallon drum. I usually add the soda when filling the tank and the resulting turbulence mixes it pretty well.

From my experience, cold temperatures do slow down the process.... Someone I am sure will come a long and explain why. I was going to try to do some today, but at higher amps since it will warm up the water in the process. But with the higher amps comes my concern of the danger of being severely shocked if I or someone else touches something as it is working. therefore I am extremely careful when using high amps and do not leave the area when it is on.

I had a similar problem with the first small tank I built. Took for ever & the water turned clear.  Turned out my battery charger puts out current & not voltage.  With the low current flow, it figured the "battery" was charged & shut itself off.  I had to put a dead battery on the charger and run cables from the battery to the tank.  Solved the problem for me.  Individual results may vary.

Same thing with my charger. I always hook a battery inline so it will do it's thing.

I have a quick question about this whole process. Is 'washing soda' just regular laundry soap?

The washing soda has the benefit of producing a "doing the laundry" smell that I find pleasant. I've used baking soda as well but like the washing soda better.  I didn't notice a huge difference in the current level when it was cold. If the baking soda is not going into solution when cold then the concentration may not be high enough to support a large current. It could be that the washing soda with it's extra ingredients is better at going into solution when cold.

Baking soda is safer to handle. Either in powder, or mixed with water. Baking has a ph level of 8.1 vs washing soda at 11. So washing soda is more caustic, therefore more of an irritant.

 

On the other hand, being higher on the alkaline scale gives it a higher ability to conduct a current. So it should cause the tank to work faster. One interesting note was a test done where the baking soda anodes ended up covered in finer particles than the anodes used when washing soda was used. It was much easier to remove the rust off the scrap metal anodes in the washing soda solution. The cathodes (items being cleaned) looked about the same:

 

Baking soda top row, item being cleaned on left. Notice how much finer the rust on the anode is on the top. (square chunk of metal)

I use feed grade sodium bicarbonate with great results.  I don't remember the cost, but somewhere around $12 or so for a 50lb bag.   You can get it at any cattle feed store.

Went to several feed stores here. Can't find it out here Daniel, :( That's why I bought the 4lb boxes at Wally-World. $2.08 a box here.  About twice as expensive as your bulk bag. :wallbanging:
