I saw a cool hydrometer that goes in the tank that has a termometer from read sea, and mardel has something like the ammonia badge but actually gives a reading.
I have been toying with Lifeguard from AS, its a non antibiotic medication basically and oxidizer like getting away with adding bleach to the tank but in a safe way, so far great results.
Havent seen anything else ...
