PP'ing Plants - How Much - How Long
This has surely been asked a million times already. At least 400,000 times by me alone.
I always always PP any new plants going into the pond. I got some elodea crispa from a well known aquatic shop and did a scrape out of curiosity. I found all sorts of things on there.
I used so much PP that the plant went brown.
What IS the correct amount to use please? And for how long?
Thanks

PP'ing Plants - How Much - How Long
Very good question that mate i pp'd all of mine in buckets when i first got them i left them for 4 hours with a dose rate similar to that if giving the fish a pp dip. Didnt experience any problems with the plants and nothing nasty in the pond once they was in. I didnt scrape them before and after though so dont know if it did work properly? May have just been lucky?

To decontaminate plants a 20-40 ppm solution dip for 6 hours should kill any nasties without harming the plants.
There's a very informative web site about pp and it's use I'll try and find it and post a link.Alias PWNN - Steve

Found this if it helps.
Parts per million (ppm), is a ratio of parts of solute to one million parts of solution, and is usually applied to very dilute solutions. It is often found in reports of concentration of water contaminants.
To calculate parts per million, divide the mass of the solute by the total mass of the solution. This number is then multiplied by 106 and expressed as parts per million (ppm). In dilute water solutions, we can assume that 1 mL of water-based solution has a mass of 1 gram, so 1 liter of solution has a mass of 1000 grams.Alias PWNN - Steve

I'm reading that as I gram of potassium permanganate in 1ml of water then dilute that solution by volume at 20-40% for a plant dip but don't take my word for it I'm thick.

20ppm = 20mg/l
=> 20mg x 4.55 = 91mg/imp gallon
= 0.00321oz/gallon.
You'd be better sticking with 20mg/l though .... lol ...
When I'm doing it I just make sure the water turns a nice purple colour and leave the plants in overnight making sure that they are all fully submerged ...

Just did some plants last night in a 50 litre tub ... put 1g of PP in (that's 20ppm), gave it a good stir, made sure everything was submerged and left overnight.
I've just taken them out and rinsed them, they're now sitting in fresh water in the 50l tub for a few hours then I'll put them in pond ...
Nearly forgot, I also put some Sodium Thiosulfate in the tub with the fresh rinsing water.Last edited by Trace; 21-04-2016 at 07:16 PM. Reason: added info

20ppm is too strong for smaller, finer plants and overnight dipping, today after rinsing some smaller plants like Elodea looked a bit frazzled ... I'll let you know what they are like in a few days.
Before this I used about 10ppm and all the plants looked fine the next day.
I think 20+ ppm will definitely have to be have to be just a few hours, mind you stronger more robust plants like aquatic mint looked fine.

Quick follow up ... turned out that the frazzled looking stuff was algae or some other type of really fine weed that the PP nuked on the outside of the plants ... plants are fine ...

Right. The container i was going to use is about 120 litees. What i normally do is put the plant in, then put another smaller container in (eg lily basket) with a brick on top. That way it makes sure that none of the plant floats to the top. So in my container i would need how much pp? And for how many hours?
I'll go read the link now too.
ADMIN - Perhaps this could be made a "sticky" for people to refer back to?

Unless you click on the report ! icon theres a high chance Admin will miss this, there is a site suggestion area, that might get noticed faster

As above ..... for 50 litres ..... 1g of PP =20ppm
so ... 120/50 = 2.4
so ... 1g x 2.4 = 2.4g
so ... 2.4g of PP in 120litres of water =20ppm
I left plants in the same overnight (probably about 16 hours) a couple of days ago and they were ok (Elodea and Aquatic Mint).
If there is any chance you are going to forget about it use 10ppm which would be 1.2g PP in 120 litres ...

Would this kill leeches? I took some plants out of my other pond today and put them in a tub. Then i put the hose in the tub. There was at least 2 leeches in there and lots of little worm things that looked like strands of cotton.
My other pond has no fish in it. Just lots of plants. So many that you can't see any water till you're up close.

You could go for the top dose recommended in the article 40ppm ... that would probably kill leeches. You'd be best to keep checking the plants every couple of hours though to make sure they weren't shrivelling up ...
The article does state that 40ppm is a safe dose for plants though ... there was a whole lot of dead things left at the bottom of my tub the other day after an all nighter (about 16 hours) of 20ppm ...

I wouldn't even risk putting them plants anywhere near a koi pond after the nightmare I went through with leeches.
