I have had my aquarium for 14 almost 15 years and this is my first experience with this stuff. I refuse to use any chemical cleaners etc. I just can bring myself to do it. I have been doing 15% water change weekly. All parameters are great! Aside from ph being a little low by 2 points sometimes. TDS on RO is 0, skimmer runs 24/7 . I do not utilize a sump I use a 150 gph and 75 gph canister filter. Lightning is a T5 6 bulb 3super daylight 3 actinic replaces every 6-8 months. 2 weeks ago I introduced pyrigen to the 150 filter. I’m about to pull that and run phosguard for the week. Even though phos isn’t showing in test I believe it’s thriving in the bacteria. If anyone has any non chemical related advice I would appreciate it. I left out the uv sterilizer but I don’t think it actually has a roll in this
