A week on here are two more photos. I've had a bit of a pruning session in the tank today.
Trimmed back the java moss which, being so high up in the tank and under the T5HO, had developed the unsightly beginnings of bba. I've moved some of it further down the log and tied it on. I've also trimmed back the shoots of the tiger lotus as they were blocking the light from the plants and have removed, for good, two of the big swords from each end of the tank. While I love their colour and leaf structure they are really too big. Theres still one in the middle of the tank which I will leave for now. At this stage ferts are still only flourish excel and flourish comprehensive.
I've added a second light fixture with 2 T5HO lights, giving a total of 4 T5HO and 1T8 light on the tank. Now that I have discovered my husband has a 6.8kg CO2 tank that I can use this will be the next addition. Going to get him on to getting a suitable regulator tomorrow
