I came across this post from people who have made their own aerators. I need to lower our TA "badly". It has been at 140 for two weeks and it won't budge. Water is now getting cloudy while CC's are zero.
Does anyone still have a picture of Poseidon's home-made aerator. The link for the picture doesn't work anymore.
Latest water readings....
CYA - 55 (I need to add more, I will do that later today)
Ph - 7.6-7.7
FC - 3.5
TA - 140
CH - 40 - just added CH this morning to raise it another 100ppm
