emersed to submersed

So i've been growing emersed HC and Dwarf Hairgrass for about a month and a half. HC is finally starting to grow in nicely and the Hairgrass is spreading runners in a couple of directions (need to change/clip a few).

My question, is how to do the conversion from emersed to submersed. I want to give it at least another 2 weeks to get the HC a little fuller. But here are my specs now.

5.5G with 18W's on for 13 hours/day. 2x weekly spraying of strongly diluted ferts (NPK), 1x weekly spraying with just water.

So should I just dump in 5.5G's of water and cut lighting period all in 1 day or will that hurt plants? I was thinking of adding water slowly over a week and cutting lights slowing to 8 hours a day.

TIA

20G (tall) - Planted. 4 neons, 8 rummy nose tetras, 3 ottos.
5.5G - Dwarf Hairgrass playland for Beta and 2 ottos.

I filled it up slowly over the week, and added Excel too. I think plants go through the 'meltoff' phase because they don't get as much co2 from the water as they do from air.

I plan on using DIY CO2. I guess I'll just start up a bottle as I fill the tank.

What about lighting?

I would suggest changing as few of the variables as possible. Plants will be vulnerable in the transition phase from emersed to submersed growth, so I wouldn't change the photoperiod until the plants have had some time to adjust.

I did the same thing. HC and Dwarf sag. When it was ready I filled it up with water and pounded the CO2. No problems so far.

ok, so a long time has passed and i should have updated a while ago, but all the HC died. The hairgrass did well, and it growing in slowly.

Any suggestions for another foreground plant in a 5.5G?

what do you think killed the HC? the transition from emersed to submerged?

if you were to do it again what would you have done differently?

(happy friday everybody!)
