I have a 110 planted Discus tank and have to be the laziest person on earth when it comes to water changes. I do a 50% water change once a mth otherwise just top off due to evaporation. I use root tabs and water column dosing once a week. My tank looks like a jungle with probably almost a dozen species of flora. Substrate in that tank is pea gravel with a ugf and powerheads (yea yea I know can't be done lol) You can make it as easy or as hard as you want it. Been doing it this way for 45 plus yrs. However when I set up my 220 I'll be using Soil Master Select so its true an old dog can learn new tricks.
