Just completed a rare weekday water change. Trying to get things back to my normal parameters as soon as possible.
So besides the fish loss, looks like more plants took a hit than I thought. Had several things all happening at once. Much higher KH, softened well water vs. RO, ferts all over the place, CO2 /pH drop all over the place, mini cycle with ammonia....basically all the things you don't want to do to your plants. Did the first WC with RO water on Saturday, and that helped stem the tide.
It took some time for some plants to show symptoms, but here is an example (sadly not a glamour shot!). Tonina sp Lotus Blossom has been a solid grower for me. Loves soft water, and was humming along. Here it it today.
Notice the brownish section on the middle one? That's a weeks worth of growth in vastly different conditions. Had a couple more do the same thing and they broke right at that spot and the tops floated away. This plant is normally algae free, but you can see how quickly it crept up. Probably a combination of not being happy and the ammonia spike. The good news is the newest growth is bright and vibrant. I am sure it will fully recover in time.
Here's another one, Rotala Tulunadensis. Known as a very difficult plant, but was I fortunate to have it humming along very nicely until now. Same deal, never had algae before, and look at it now. Once again the very newest growth is nice and vibrant, so I am hopeful it will recover over time.
You can also see the Rotala Macranda Variegated just to the left of it. Once again, some uncharacteristic algae, and lots of stunted tops. Going to trim it back pretty hard sometime this week and get some new fresh tops going.
Others that aren't faring well are L. Pantanal, which has lost a lot of color. No surprise Rotala Wallachii stunted as well. Like the others, it's showing signs of recovery and is now throwing out some nice pink tops since the RO water change on Saturday.
So a pretty good example of don't change too much too quickly, and stability is a good thing. Still most plants held up pretty well, and the ones that didn't are not surprising to me.
After this water change I should be pretty close to usual parameters. As least much closer than a week ago.
On a side note, I timed the new pump and was pleased. The water is pumped up a little over 14' in 1/2" pipe, and it took 17 minutes for 70 gallons. So about 250 gph, which is pretty good given it's going up a floor.
