Evan Posted October 5, 2022 Share Posted October 5, 2022 I can’t believe I’m even asking this but …. The directions for the larger bottle say 1 ml/10 gallons. The directions for the smaller bottle say 2 drops/1 gallon. I bought the smaller bottle. Can’t I just add 1 ml/10 gallons or do I really need to count 110 drops for my 55 gallon tank?

TOtrees Posted October 5, 2022 Share Posted October 5, 2022 If you don’t follow the instructions on the label of the specific product you bought, the end-user warranty will be void. In your case, if you measure in millilitres instead of drops, the metric conversion (because your tank is in gallons) could result in over application. …. …. …. …. Bwahahaha just kidding. The product in the two bottles is the same. Same concentration and everything. 20 drops is generally accepted to equal 1 ml. So two drops per 1 gallon is the same as 20 drops or 1 mL per 10 gallons. 1 1 1 Link to comment Share on other sites More sharing options...

Seattle_Aquarist Posted October 5, 2022 Share Posted October 5, 2022 Hi @Evan 1 ml = approx 20 drops So the dosage and the concentration are the same on both bottles. You may have a 55 gallon tank but the substrate and hardscape will take up some water volume. I have found in all of my tanks from 75 gallon to 10 gallon that with gravel and hardscape I lose about 20% of the tank volume (yes I measured). So I would assume your 55 gallon has 55*0.80 or about 44 gallons of water volume. Hope this helps! -Roy 1 1 1 Link to comment Share on other sites More sharing options...
