If I do buy sieve screens (which seems the most reliable way to get the right sand grain size) What is the least expensive reliable option? The sieves I\’ve seen on the internet seem to cost $40 US Dollars each. This is cost prohibative. Are there inexpensive sieve sets I\’m just not finding? This is the only missing link in our biosand project, Help! Thanks -Jesse
