Well i posted a thread about a week ago about using Alum in a setup aquarium with plants only, to rid snails. I have purchased alum sulphate in a 25 lb bucket for cheap and dosed the tank at 3tablespoons per gallon. I have a 50 gallon aquarium with a 30 sump. Day one has passed and all snails and bugs are little dead white specs in the tank. i still have snail egg sacs so im going to wait until i no longer see any of them before i attempts water changes and slowly ridding the tank of the alum. My plans after words are to put cherry shrimp, ottos and rams in the tank once my jungle of plants starts to explode in growth. I will first test ghost shrimp prior to putting anything in the tank to make sure its safe. I plan on doing a few 100 % water changes and a constant carbon filtration. I have had the plants in the tank for a month even with the carbon filtration on and they have all rooted well and started to take off in growth. So these are not plants i just recently purchased..Well i thought i would try this to be clear on whether or not it would work..So far so good the plants look great!.........Please let me know what you think or if you have any advice. My hope obviously is that this works and others can emulate this experiment to permanently rid snails and bugs.
