Hello. I’ve been running my 45 gallon tank since the beginning of October (that’s when I started cycling it). It is planted, and contains : 3 khuli loaches 2 Yo-yo loaches 3 guppies 4 Amano Shrimp 6 rainbow fish 2 plecos I have been researching and it seems no matter the question there is conflicting info on the internet. I got some good advice a few weeks ago when I had some troubles with the water in that tank, so looking for advice again. I am running a fluval 306. Looking specifically for tips on the charcoal packs, but will willingly listen to advice on all filter Media. Thank you.
