Since the last post, I did switch to
@Burr740 ’s all-in-one for low-tech for all of my low-tech tanks, and with then unused heads was able to set up an auto-top off of sorts for the Hillstream tank and send ferts to the quarantine tank. I think I may need to up the dose for this tank, because my Java ferns are getting a lot of black spots, but I forgot to check nitrates. I’ll check them tomorrow to find out.
I had 2 fish deaths this week, one somewhat expected and the other unexpected. The skimmer on the right side had gotten sucked down below the water level, and one of the gouramis got pulled into it tail-first. It was too big to go down the pipe, but apparently couldn’t free itself either.

The other death was the Glo-fish Rainbow Shark. It had been getting steadily thinner along with a very curved back, and doing a lot of resting on rocks and plants. I had tried treating with Prazipro a couple of times with no effect. About the time I was thinking about euthanizing him, he passed away on his own. I think he may have just been a victim of Glo-fish bad genetics. I won’t be buying any more of those, ever.
I raised the outflow pipes to create more agitation and put mesh into the lids in hopes of getting shimmer from the lights. It did improve, but is still pretty subtle compared to the Hillstream tank. With the added surface agitation, I don’t think I need a skimmer, so I capped it.
I also cleared out more Leopard Val because I wanted to see the big Red Rubin Sword better. Now it looks odd though, like a big, blue rectangle there. I moved one of the smaller Crinum calamistratum in from the Hillstream tank to see if it will do well and if I like it. I’m getting a little tired of keeping up with the Val, it’s so aggressive, so I’m considering alternatives.
The sand, well, I’m not sure, but I think there might be blue-green algae in it. Either that or it’s regular algae, but I see some below the substrate surface so I’m suspicious. I treated it today with Blue-Green Slime Remover. If it clears up, then I’ll know.
I think that’s it for now. Any suggestions to improve this tank are welcome. Thanks for reading!
