The Macro Algae reactor is slowly starting to do its thing. Nitrates are slowly coming down and the rate of increase in PO4 is decreasing.
If the trend continues, then it confirms something that I have been suspecting since I installed the reactor: it takes time for the chaeto to grow to enough of a size to start having in impact. Plus the die off of the GHA that I had on a part of the back wall of the DT must have been adding Nitrates and PO4 to the system. That GHA has basically disappeared now.
Two days ago I harvested about 20-25% of the chaeto in the reactor and this is what it looked like. The laptop is a 13" laptop for size comparison. The chaeto in the reactor was getting quite dense but no die off at all that I could tell from lack of room or light...
