Above flowrate will produce 60 drops of water per min, 3600 drops per hour or 86400 drops per day or 8640g (10 drops approx 1 g) or about 8.64 litres of nitrate free water/day or about 1.79 % of 5' tank water (85% full ).
See what I mean? If above figure is right, think it will not ..........  |
thks ken for the superb calculation and keeping in focus. lets say 2% of nitrate free water everyday and tat will be 28% of nitrate free water every 2 weeks. which is equivalent to 30% water change every 2 weeks. tat will work out to be a great saving. another assumption is tat the de-nitrator starts operating at a negligible nitrate tank water. tat means we need to do constant and frequent water change before the de-nitrator starts coping with the nitrate load. tat also help to explain why initially we need to "feed" the anearobic bacteria to colonize. thks again for the chance to explain further. it may be old design but its serving me very well
