T5 are usually 54W bulbs(?)
Consistant CO2 is better even if much lower but/w 4 bulbs you do need it if only
fairly temporary. If the fixture will work/w two bulbs it would be better till you get good plant growth. Those 50/50 bulbs usually have 10,000K for the non blue half which is
likely in the high range/w 4 of them. But check your fixture on the T5 chart on this.

Using a lot of guess work it seems to be 80-90 PAR and half of that may not be enough for the Dwarf Hairgrass.
Either add fish now or keep adding ammonia till you do or the beneficial bacteria will die.
