so for my 75 Im gonna do an amazonian blackwater creek biotype. i want plants but i dont like using large amounts of electricity. so i hear theres sword plants and vasillineras in this ecosystem. so maybe subdued lighting will be ok for these types of plants? im gonna use co2 and eco substrate to help them out a little. so im gonna start with low lighting maybe like 50-60 watts or somehitng then see how they do
