Hitting the first problems and finiding solutions

By mid-November, the newly set up, fish-free tank already showed some problems, the biggest being the appearance of fluffy clouds of dark green algae along the surface of the substrate. To counteract this, I suggested reducing the lighting period (which had been set to around 12 hours by the family) to 10 hours. I also gave them some Spirodela spp. which is a type of giant duckweed that can have a nice red tinge and a bottle of EasyCarbo, a liquid carbon fertiliser which also acts as an algaecide. We then manually removed as much algae as possible while doing a water change and left it at that. I also gave them some sera Florenette A root tabs (which are best value for money), two of which were inserted into the substrate at the time.

In that 6 or so weeks, some of the plants settled in nicely and some died off. Mainly, the Limnophila sessiliflora tried to take over the tank, while the Bacopa lanigera, Lindernia rotundifolia and Lysimachia nummularia ‘Aurea’ died back heavily. This corresponds with my experience that without investigation and special attention, some plants just take to some tanks while some just don’t.

The other problem that the family encountered is high levels of evaporation as can be seen in the photo below. With the tank temperature set to 24°C, this was unexpectedly high as I get considerably less evaporation in my “hot” tanks. The problem with topping up is that it increases the water hardness in the tank, and disturbs the substrate, but this was resolved later.

In the mean time, I had failed to find my background for this tank, so it was looking a bit bare without one. The sagging lid was also irritating everyone.
