check the # of the nitrate now and wait at least one week to compare it (again from the effluent) the change not made quick you need to be patient with it and when you see it's go down to 0.00ppm then you can stert to compare the tank nitrate to see how it's reduce (in the tank) and this take time to (at least 1 month) also it's depend how much media you have if it's not enough it will be hard for the reactor to reduce the nitrate to 0 ppm .
the first thing is to read from the reactor 0. ppm and after that (before increasing the drop) you want to see how the reactor effect on the tank nitrate and if you see the nitrate in the tank drop then you can increase the drop.
for the future you always need to test the effluent because if the nitrate will go up again you need agian to reduce the drop...and so on .
xinumaster :
you can see in the picture the left side media it's the Carib Sea
the right side it's the H&S media , both media work but when the grain small the reactor will clog all the time and it will be hard to control on the drip when you use bigger grain it's easy to control on the drip (will be more steady) i suggest to go just with the big grain media if you want good and steady result.
