Another big epiphyte trim 10 months after the last one
another big epiphyte trim 10 months after the last one

The last massive epiphyte trim was nearly 10 months ago, so time to go at it again.  I didn’t actually mind the overgrown appearance and the fish seemed to like hanging out under the middle layer of Anubias nana ‘Pinto’.  There was considerable shading of the bottom of the Fireplace Aquarium but I didn’t notice that particularly being a problem for either the Cryptocoryne petchii pink or the Microsorum pteropus ‘Windelov’ so that was ok.  What finally pushed me to get the scissors out was the increasing amount of black beard algae that was growing on the leaves of the Bucephalandra caterina at the top of mountain on the side in the middle that gets the most light.  BBA that gets established is notoriously difficult to get back under control so I figured the best way was to remove it physically altogether.

Regular and substantial water changes for an aquarium are a good idea.  With EI fertiliser dosing the built-in assumption is that at least 50% of the water will be changed out every week to prevent a build-up of excess fertilisers.  Both the Fireplace Aquarium and the Shrimphaus follow this maintenance schedule, although lately I have been doing around 75% water changes to better remove organic particulate debris from the Fireplace Aquarium and to remove salts from the Shrimphaus.
