Ok forgive me if I get this wrong as I'm very new to all this ☺️First set up jan 2013 put a juwel background in and had a few plants & ottos and that was it , .. Nov 2014 emptied it out put all new substate in Ebi-gold and it looked like this ... It's got a juwel internal filter in the corner and I also have a tetra 1200 external as well plus lighting is juwel T5 s high lights 2 x 54 watts day & 2 x 54 watt nature I have co2 as well have lights on 6 hrs aday ... On the left hand side I built a rockery out of dragon stone , and on the right I covered the internal filter with Java moss .. The back wall I put pearl , creeping , string moss & Christmas moss on with superglue think I've covered everything
