Post-holiday update and maintenance

My friend came twice to check on the fish in the two weeks that I was on holiday and each time did a small water change, then fed the fish.

The hair algae has made a come back, while I was away, so I’ve had to pull out more of it. It is growing predominantly on the side of the aquarium where natural sunlight falls. I also gave the plants a trim and did a 15% water change. While I was on holiday, I managed to trade some Crypt. for water sprite and Riccia.

Water parameters are nitrate at 30 ppm and pH 7.4-7.6, I also tested for ammonia and nitrite, which I would normally not do in an established aquarium.. both were 0 ppm. Filter claims that it does not need cleaning, so it didn’t get any.
