I have a 20g Long, Black Diamond Blasting Sand substrate, a ZooMed UltraSun 6500k bulb, 2 sponge filters rated for 40g each, and 6 Serpae Tetra. There are 17 stems of Bacopa Caroliniana and 1 Broadleaf Saggiteria with 2 more root systems coming in. The tank has been set up for about 4 weeks, the plants in for 3 weeks, and the fish have been in for 2 weeks. I have been dosing 2.5ml of Flourish x2 weekly. The Sagittaria doesn't look any better than it did when I planted it, and the Bacopa has gotten really brown and the stems have gotten soft. Algae is starting to become a problem. Could this just be the transition stage from possibly being grown emersed, then I submerged them? I have 2 oto cats in my 29g, they've worked wonders for that tank. Is it worth moving them to my 20g? (Which I planned on doing in a few months when the tank is more established, and try to get some more.) But since the tank is not established I don't really like this idea, even though I got lucky and the 2 otos I have like shrimp pellets. In this picture you can see a Bacopa laying on the substrate, this stem is soft, not firm. In this picture you can see all of the algae on my fake hide, 1 filter, and my heater. There is not much growing on my tank walls or the driftwood. But my moss balls are also either getting algae on them or something is happening to them, too. I'm also getting some hair algae on the tops of some of the plants. The water parameters in this tank are (please keep in mind this tank is still cycling): Ammo- 0ppm Nitrites- .25ppm Nitrates- 40ppm I am also getting things ready to do a 50% WC tonight.
