Hi iter,

Sounds like a great project I do have some concern about
- Giesemann Midday and Aquaflora (both bulbs 3+ years old now)
At that age the bulbs are likely putting out well less than 75% of PAR and the K value is likely shifted as well; if algae becomes an issue this is the first thing I would suspect.

Also the stone chips could easily be limestone which is used a lot as a base material for concrete and asphalt roads; do a vinegar test prior to putting them into your tank.

75 Gallon, 2X55W AH Supply CF 8800K, 1XFluval F&P 2.0 48"/59W, 2X Marineland 350 Magnum filters; 45 Gallon Tall, 96Watt AH Supply CF 6700K, 1X Marineland 350 Magnum filter; 30 Gallon Long; Fluval F&P 2.0 36"/46W, Marineland C-220 filter; 20 Gallon, 1X26W AH Supply LED kit, Marineland C-160 filter; all with Press. CO2 and (Calcined) Montmorillonite Clay
