LOL!!! I dont have the calculator in front of me but i thought the amount sounded a bit high. Recalculate it to 4ppm- 5 is a bit of an overkill. 5mls=1teaspoon but do not use a regular teaspoon to dose, use an actual measuring spoon because its a bit smaller than regular 'teaspoon' in the kitchen drawer. This where a 5ml syringe really helps for accuracy-this stuff is POTENT (do not sniff the bottle, it will knock you on the floor!) so round the any 'in-between' amounts down. You then can wait 15mins & test your tanks amm levels. If its not quite 4, its easier to add a little bit more than dose too high & have to do a big water change! I did this test before & i dont recall the exact number, but its something like 15-20drops of liquid in 1ml if this helps for smaller amounts. Happy dosing & keep us posted!
hahaha. 5ml= 1ts, so if its 23ml for 5ppm for 120 gal..... ok where is the "my head is friggin spinning smiley"? Let me calculate (insert Jeopardy theme).... 4ppm would be 19.13ml... so we are talking just short of 4 teaspoons of ammonia for 120 gal...
