Ok as most of you know i own a Spec C but i have a little problem, it has a 12ltr water tank in the boot, and no doubt given enough time it will start to get the green fungus stuff forming, now as this sprays onto the engine i dont really want to put something like methonol alcohol in there, would screen wash suffice to stop the green stuff??

Try using boiled water rather than straight from the tap....


All the best

I use filtered water. Also a tank of water lasts me only a couple of days because of the automatic spray

 

You can get an additive used in fishtanks and the like...green algae control....copper sulphate...might suggest you ask if its ok to use for the purpose that you want to use it for, but seeing as you put a very tiny amount into the water, it shouldn't cause a problem...best ask someone in the know first tho

 

It only gets sprayed onto the intercooler so it sounds as though it could be a good idea

PS, i would put distilled water in but it would take me a day to boil it all up, let it cool down again (considering that 12ltrs is around 2.5 gallons its quite an ammount!)

 

The copper sulphate additive is called... Green Algae Control, made by King British and available from pet shops and garden centers with fish sections for £3.99 for 100ml, you put 1ml to 2 gallons of water, about once a fortnight.

 

I have a spec C myself . Only use distilled or boiled water, having access to limitless free deionised water helps .
I would'nt use tap water from my part of the world, as the carbonates in the water will eventually block the spray jets.
Same goes for copper sulphate, did you ever grow copper sulphate crystals from solution in science lessons when you were at school.

 

In the dilution that is used for fishtanks and ponds, there won't be any damage done to things sprayed with the water...

 

Doesnt matter how dilute the solution is, as the spray leaves the jets the copper sulphate will precipitate out of solution. Some will end up on the intercooler, some will collect on the jets.
The only effect the concentration of the solution will have, is on the rate of material deposited.

 

Its a very very minute solution as used in fish tanks to keep green algae down, its 1ml per 2 gallons of water...hardly enough to notice but does the job very very well...stops formation of green algae in contained water, does not collect on jets or anything else...my tank has 14 tiny jets and I been using the additive for 6 months now and no deposits have occurred.

 

screen wash contains methonal alcohol, you could put half a capfull or sodium hypochlorite in (bleach).

 

as the boot is dark algae will not grow very well?

 

Algae is one of the most annoying things cos it doesn't actually need light to grow and mature and spread.

 

buy a britta water filter or 3 and mod them so they drip into a bucket or sumthing and leave them under a slow running tap

 

what about something like milton cleaning stuff used for babies bottles etc? would this stop it???

 

Put a Pleco in there?



Sorry I'll get my coat....

 

i wouldnt use copper sulphate overtime it will block up your jets, definatly not bleach might damage your paint ovetime aswel i would go for filtered water, but distilled water is the best luckly i work in a science we got a massive ion exchange barrels

 

Lone wolf, the reason the copper sulphate does not block the jets in you fish tank, is that the water from the spraybar (in your fishtank) is at low pressure. Consequently the water droplets are either very large or non existant.

However the water spray system on the intercooler, has been designed such that the water exiting the jets is at a relativley high pressure. This causes a fine spray of water, with relativley small droplets.
The reason for this, is that when the small water droplets come into contact with the intercooler, the water evaporates (very quickly). This results in the cooling of the surface from which the water has evaporated.

Furthermore a fish tank is a relatively humid environment, this would tend to help keep the copper sulphate in solution. I think that you will find that under the bonnet of your average scoob, the air is far from humid
