Pies does make a valid point that I am the distributor of salifert and rowaphos,
Wasp makes very good points.
Pies claims that hobbyist have problems with the Salifert products which is a liar as there is no proof.
There is info on iron based phosphate remover which does drop your ph a bit, so if you add kaltwasser this is not a problem.
I have been using both products and have never had any problem, nor has anyone in New Zealand. Salifert phosphate killer has a big following in New Zealand and is the most popular phosphate Remover.
Aqua medic which is sold by his friend Steve( jetkski ) like salifert/rowaphos are also iron based. So a total contradiction by Mark as he now uses Aquamedic and then wants to use rowaphos which is also iron based.
Ben , If you try some of the phostphate killer I will give you a 100% refund if it does not work.Email me and i will send you a small sample) Also don’t worry about the Liars by Mark as he can’t provide any details of hobbyist having problems with the Salifert product. There is nothing on the Net that blames Salifert for any problems, And if he does it will be a isolated case.
Mark is fairly new in the Hobby so his knowledge and experience is very limited and all he is doing is trying to put doubt in your mind about the Salifert Phostphate so he can promote Aquamedic which is not really stocked by any shops.
Ben i have the most expensive tank in New Zealand and if i was having any problems i would not be distributing any of these products.
The best way to use the salifert product is to put it in a canister filter so you push the water through it, this way you will get better water contact
