High energy only so far, to varying degrees.
I have a 90L with wrgb2 and a 1.4 drop, buffering ada v2, 0kh 3gh.
I have a 60p with the ADA Aquasky RGB light, and a 1.2 drop (much milder on the light intensity and ph drop), much milder also on the substrate which is controsoil. 0kh and around 5gh I believe.
The 90L has been giving me alot of problems with bba lately despite impeccable maintenance and even flow distribution, it's an interesting contrast with the lower energy 60p where algae isn't a problem. Not sure if it's indicative of something being out of balance with light and co2 or just a coincidence.
The 4820 I'm in the process of starting up will be much the same, but as high energy as I can manage, gradually ramped up. Lighting driving it will be a 6x54w T5 fixture, I'll be trying to match that up with a 1.4-1.5 ph drop and moderate dosing (12/4/14 on my other tanks now, I'll probably start with this baseline and add po4 daily into the sub stops adsorbing). Substrate is going to be 50L give or take of Landen.
Once I adapt to having three high-energy tanks to maintain, I'd like to take the little 7 gallon I brought back from aga and make it a low-tech. I feel like I will struggle with low tech because I've never done one and it's hard for my mind to switch gears into low-to-no dosing, sane levels of par, etc lol. I wouldn't have any idea how to do low-tech effectively, so it would probably be a cool challenge for me...and if I could get used to it, the result would be a nice slow tank with some hardy plants that just looks like a calm, still picture, instead of a bubbling explosion with 10x turnover glaring at you from the corner of the room with the angry light of the sun
