So, I'm thinking of getting some PP, because I've been experimenting with new plants lately, and many of them cannot handle bleach too well. However I have many questions, so I decided to compile them into one thread, rather than clog up the subbie forums. Hopefully others can learn along with me. Brace yourselves, I have a boatload of questions! - From what I have browsed on the forum, it seems that PP has no set measurement or ratio? All I have collected is you keep mixing it in until it's dark, opaque purple. Anyone have any general measurement of how this is achieved? Does it take a few teaspoons? Tablespoons? Granted, I know everyone sterilizes in different sized containers, but I think the estimation of around 2-3 gallons is about the average. - Once you get the water a dark purple-y, how long do you leave it for with the plants? I know it's in the hours range, does it vary based on the plant? For example, stem plants should be in for about this long, swords for about this long, anubias this long, etc. etc. - Does PP stain plants at all? What about sinks, bathtubs, etc.? What about skin? (I would be wearing gloves, anyway) If it does, how easily does it come off? - I assume you dip the plants in dechlorinated water after the PP dip, yes? - How effective is PP at killing pond snails and snail eggs? What about algaes? - Is PP irritating or damaging to the skin at all, if you accidentally get some on you? - How much should I buy? I don't buy plants too often, I'm not sure if I should just get a pound or a quarter of a pound, etc, etc. OK I think I'll leave it at that, and if I have more questions later I will ask. Thanks for your time!
I have just had a disaster 'sterilising' my new plants with potassium permanganate. I bought £35 worth of various vallis, crypts, and elodea. As I've had some bad experiences in the past with pest snails, I read the 'Plants for Goldfish' page and found Koko's advice on using potassium permanganate to rid plants of unwanted pests. I followed the instructions correctly - I measured the water out exactly, I weighed the pp out using electronic scales, I even left the plants soaking for less time than recommended. However when I got them out of the bucket nearly all of my plants were black and dying. The only few plants I could salvage from the catastrophe were a few crypts. I'm absolutely gutted Please don't anyone use this method if you don't want to be as disappointed as I am, and £30 worse off. Koko maybe it would be a good idea to put a warning on the 'Plants for Goldfish' page about this method? I'm sorry that my first post is so negative, I just don't want anyone else to kill all of their plants before they even get them in their tank! Kate
I have been putting off ordering PP for awhile now, but figure I should have some around. I just want to confirm that this is the correct type of PP (not sure if there are different types ) Thanks! http://www.amazon.com/Potassium-Permanganate-Treatment-Manganese-Greensand/dp/B0034UCKWE/ref=sr_1_1?ie=UTF8&qid=1331597173&sr=8-1
