![]() ![]() Ploylap link: http://www.polyplab.ca/ocra-laborato...lts-1000ml.php In theory they will do what bio-pellets or Zeolite's will do but in a much simpler method. We all know that Bio-pellets and Zeolites are great at reducing nutrients but we also know that you need to be on top of things and employ strict maintenance with these products. Nitra-guard makes it a little easier for the masses....and cheaper. thanks |
