I'm looking to switch ferts I have a 20g low tech and 40g high tech both currently getting a mix of apt 1 and 3. I'm wanting to switch to pps pro using the gla salts (cheaper and gets my foot in the door with the dry ferts) for both tanks, but I've seen some recommend against it for low tech, I have no issues dosing daily, actually prefer it, and if I understand correctly, its actually better for the tank as far as stable nutrient levels. My question is, can this be done? Is it really that much of an issue to go pps pro on a low tech? I really want 1 solution (i.e. macro micro mixes) for both problems (the two tanks (obviously they'll need their own amounts as for as dose size)). I'm limited to 20 gallons of clean water at a time (remineralized with apt sky plus to 6 GH since I have neos, amanos and snails) due to space constraints so I can either do weekly 25% changes on the tanks or 50% changes every other week. Any and all input is welcome. TIA
