HI all i am new to UKAPS but have been keeping fish for many years now and plants for about 5 years. I have set up a 180l tank with the All pond solutions ef2000 with uv it is well planted i use TPN+ and Easy life Profito as there is no iron in the TPN+. I have put a small hydor 900lph power head in near the bottom to help with flow as the tank is 20 inch deep. i have 4 TMC aqua grow led lights and as the thank is a divide we had made there is 5 50w spot lights as well i ave a jbl co2 on a timer which comes on 2 hour before lights on and off 2 hours before lights out. i put 10ml TPN+ and 4ml profito per day a good 4 hours before lights on my lights are now on for 8 hours a day. most of the plants look fine apart from HC and the Pogostemon helferi are looking a bit yellow the scape is 5 weeks old i use jbl aqua base and jbl mandano. i never gave ferts for the first 2 weeks. I bid a 8 week fish less cycle before planting i use 50% tap water to 50% RO and do 50% water change every week. i would put a photo up but don't no how to. look forward to your help
