Thanks. Im getting mixed reviews. We are trying to get rid of diatoms / brown algae. Everything else is great. We have a 125 gal
with a fluval 405 and an eheim eco pro 2236 and a 55 gal
with an eheim 2236. Parameters are alll good as we do 25% water changes weekly. We have multiple live plants and even invested in the exp. Chemipure media. The brown junk comes back. Dont know if a uv
would help or hurt; or even possible with 2 can filters on the 125. Our water stays clear, we are just trying to further improve the overall health of our finned friends.
