| i have a huge TT using 75 milk crates filled with Matala. when i first set it up about a year ago i had a huge string algae growth in the pond. the algae was much less but the first few months i didn't have a great water distribution over the media. about three months ago i made a drip plate with hundreds of holes to distribute the water.
since then the nitrates have dropped to almost unmeasurable. the water is clearer, there is less sediment, DOC's are much less also.
i believe there is less sediment as BH proponents claim as more crap is metabolized or is the word mineralized. DOC's have decreased also i believe as a result of mineralization. when first set up there was so much foam for weeks it looked like a major PP treatment. the picture with the foam is two weeks after set up.
all without BH media.
