Notes:
Green algae seems to have decreased noticeably after the water change, even the green water has improved. Perhaps the difference was switching the CaSO4 to CaCl2? Too much S from all the other fertilizers?

Python faucet attachment broke, had to use bucket brigade. UVS still on. Since all the Mg/Ca/K fertilizers are sulfates, tried to switch out the CaSO4 to CaCl2 to see if plants respond better to less S/more Cl. Also reduced K a bit to see what minimum dosage works best. Still have green water. Might have to resort back to getting the diatom filter...

Notes:
50% water change:
20 mL Amquel+

Green water still persists. Noticed holes in the kleiner bar sword plantlets, does not look like nutrient holes, since they are many and irregular, and the leaf is otherwise very healthy. Perhaps the large snails that the loaches aren't picking off are eating holes in the leaves? Otherwise, the clown loaches are doing a good job at demolishing the small snails.

Adding some K during water change, since it seems that not enough is being added from the KNO3 and the KH2PO4 at the water change, although enough seems to be added by the cumulative dosing at the end of the week.
