Before leaving, I made up one pack of food per day. Going by how many packs were left when I came back, the fish were fed every 2 days out of 3.
A head count showed that there had been no deaths and the general health of the fish was great. The bristlenose plecos had spawned and there are young all over the tank, the majority on the filter outlet or the glass near it. The new Hagen pump was quite clearly not strong enough to suck them in.
Water readings are fine, except a 25 ppm increase in nitrates. I am slowly resuming the water changes on a daily basis.
There was some hair algae in the plants which floated to the surface, which is a pain, but nothing can be done about it.
Equipment was functioning well, same as when I left it.
