Yup. More light for less time discourages algae with no ill effect on plants even below 8 hours. However, if you have WAY too much light as you say you can cut intensity (say by blocking some % of the light with tape or window screen) and then you can extend to 12hours. Too much light is an easy fix. Too little light plus too long a photoperiod as an attempted fix just grows algae.

Ver. 1.0 80 gallon dirt goldfish tank (defunct)

Ver. 2.0 bare bottom same tank another approach (defunct)

Ver. 3.0 Pool filter sand same tank now

Goldfish are among the worst fish for beginners.
