That cant be right , it works out that 200 balls gives 2 layers of packed balls in each section of my tank , that would equate to about 20% of the volume at a guess ?

Top tip thanks, put holes in the balls with soldering iron as per the link put them in tank problem solved. Happy.

[Dave Anderson]

Got 400 of them to 'hole' and put in my tank ..... oh the joy 

[G Griffin]

New balls, please.

[Tosh]

I feel a bath-related experiment coming on.

[alank]

Don't use the soldering iron in the bath though

It's fun to watch.

Just got home and the new 400litre upright has arrived.... in the picture its currently on its side i.e but I have stacked packets of 'balls' (6.5cm dia) ontop, each packet is 100 balls.....think I am going to need a few more..

[Smudger]

more than enough there Dave

your looking to disrupt the wave which that amount will do nicely - remember the holes will defuse the waters momentum
the balls themselves do have to be packed solid

Maybe I'm seeing it wrong but that tank looks baffled and it doesn't look to be an upright.

[tlwcs]

I thought the same at first, but I think we're looking at the bottom of it

[Dave Anderson]

turn it 90deg to the right  , it has a limited amount of 'baffle' but I still want to reduce it further.

[Smudger]

the  "baffles" in these tanks are really there to rigidity to the tank and make the moulding process easier - they have very limited use to stop water movement - the balls or irrigation pipe or even plastic plant pots will keep the water stable and therefore a much safer drive

Ah, its your lid and fittings that confused me.

[Dave Anderson]

Ah I see now.... in the centre of the tank is not an opening.... I had orderd 2x additional 20cm non vented lids for my other 2 tanks, thats what you can see

[bobplum]

we used 25 mts of perforated drainage pipe

So i thought i would top my plastic balls up in the tank but not looking forward to the tedious puncturing of holes in them. So thought I would check the supposed specialised balls for baffling my tank.
As you may see from the screen shot they recommend 1 small ball (same size as soft plastic play balls im using, i think) for every 7ltrs of water. So 500ltrs max = 71 // 72 plastic balls!! Doesnt say about size of the container or filling size of the container with them but a simple recommendation of 1 ball per 7ltrs of liquid.



Went on another sight and when i saw the price.......im now looking forward to the tedious puncturing of holes 

[Shrek]

Iv just ordered the 75 pack, cheers for the link

[P @ F]

A snip at £230 for my 350 

[G Griffin]

New balls, please.

Are you mad?
Not at those prices!
