Really sorry to start up another thread, but I'm completely lost and totally confused. First a bit of background: At the moment tank is 120l, 1x 36w T8 about 25% plant coverage of swords and Hygrophyla. Currently dose with easylife easy carbo and profito. Oh and lots of algae of pretty much every kind. This is mostly due to N and P defficiencies So Ive finally given up and invested in some better hardware. So, the re-fitted setup will be pressurised CO2, 2x54 T5s and a proper dosing regime. Also plan on adding a lot more plants. Ideally I want a low meintenance regime, as im quite often away so a weekly dose would be best with 25-30% weekly water change. Unfortunately this is about as far as ive got- I've spent the last couple of days reading through topics, journals and articles on here, and have only got more confused. A massive thank you for any help you can give!
