I left for a month of vacation and I've had my roomate top off the tank with distilled water since my pH was so high. When I got back nearly all the water sprite disappeared. The tank was covered with water sprite before! Now there are only a few sad pieces with little to no roots at all. I was thinking maybe this could be because the water level was kept pretty high and close to the light...I have a HOB filter (which i'm going to replace with a power head today) so I wanted to keep the water high. ...but now even as I've let it drop, I haven't seen any growth at all with the water sprite. There's been some algae growth though! Whats going on with the water sprite? It was multiplying like crazy before. pH is still really high and I can't keep it down despite the distilled water....

aside from this one of my killifish looks like it's going to kick the bucket soon too. He is still eating but looks less active and his tail seems to drop below the rest of his body. The rest of the fish look great and there has been other plant growth. I can't seem to revive the water sprite though.

Any ideas?

Maybe ur roommate got hungry? Just kidding.
But seriously the only time I seen water sprite dissappear was when I put it in a goldfish tank where it got eaten.

The only thing I can think of is since you were using distilled water, all the metals were removed and there was not enough metals (iron, calcium, etc.) in the water that your water sprite simply died.
Have you asked your roommate what had happened?
Try putting normal tap water back in. Fish can adjust to gradual Ph changes. It's the drastic changes that hurt them.
What is your current Ph?

I don't have goldies but yes, my roomate is a vegetarian.
she doesnt' know much about aquariums so she wouldn't know what happened. The other plants grew a lot so I suspect she didn't eat them

ok, I will definately take it out and put it in a glass of tap water for now, since I dont' have any prime left. I hope it works because there is only one leaf left! I'll see what happens. Last time I had the guy at the pet store test it and I think it was 8.5 or 9...so some people here suggested I add distilled. I dont' think the distilled water helped (maybe because of the HOB, even though the water level was kept high.... my pH test kit at home doesn't go so high, so I don't know the exact pH now but it still gives me the highest color reading.

poor water sprite!!!!!

I should have been a little more clear about the tap water. I meant like a water change. Add some of the needed metals back to the water column. Or go ahead and put it in a bowl/cup and either set it in a window, or outside. It should take off especially outside. Like a nano pond.
I fought with high Ph too. I just gave up. So far no issues with fish or plants. It's been about a year that I gave up trying to keep the Ph in check. Not too sure what my Ph is right now.

yea, I got what you meant, but I have to buy more prime before I do that. For now I put it in the window. I actually have some watersprite outside in a pot with a mosquito fish.. and it hasn't grown .. it's been in there for a month or so. There are roots though, so it's not like this

Oh yeah, I swear I read that about the Prime.
Wow, that's odd that it hasn't grown outside. Hopefully things work out. Water Sprites pretty cheap. They give it away at my LFS.

Water sprite does not like a high pH primarily because a high pH means that CO2 is low. Water sprite is definitely a high CO2 plant, and can easily be out-competed for CO2 by many other aquarium plants. In order to save your water sprite, you have to keep it in a tank where it is not competing for CO2 with other plants that are better at pulling CO2 out of the water. If you have a lot of fish in the tank that produce CO2 faster than the other plants can remove it, the water sprite should thrive. A bad situation for water sprite is when you only have a few small fish, bright light, and plants that normally grow submersed, such as Vallisneria, Eigeria, Ceratophyllum, Najas, etc.

So this leads me to an observation. I've had "water sprite". Very flat, no carbonation, just horrible....ok, bad joke.
This sounds like a great example of different plants being called the same names. I've had "water sprite" and it grew like crazy! I have a NPT, so no CO2 dosing.
It sounds like all the right signs as you describe HeyPK. I wonder if my experience may have been with a different plant, called the same thing.

Here is a picture of water sprite, two varieties, growing with a good amount of CO2 from fish. Also, there are not other plants competing for CO2.
