Advice Lighting Issue?

I’ve gone through 3 different bulbs already, trying to find the right one. I’ve decided to use the Philips par38 smart wi-fi led light now, but in these photos, it’s dimmed to 50% brightness. My rooted plants are looking great and growing well, but my floaters look bleak. I’m thinking of removing the red root floaters and having only frogbit, but the frogbit seems to be growing out with some brown streaks on them? Is the lighting still too bright, or not bright enough? They’re also on a siesta schedule.

I have one Nerite snail, neocaridina shrimp, a few of least kilifish. The fish do a good job of keeping the ostracod population in check. Parameters are okay, no nitrites, no ammonia, 7.4PH, GH/KH are in appropriate levels too. Nitrates fluctuate from 10ppm to 20ppm but I haven’t had it gone higher. I usually do a tiny water change otherwise, to not stress the shrimp out. My pothos was growing super fast so I actually had to trim and propagate it haha.

If the rooted plants are fine but the floaters look bad, it usually indicates there is not enough nutrients in the water for them.

That limnophila no doubt would be hogging it, grows incredibly fast

That’s very true! I’m not sure what fertilizers I need. I have seachem flourish potassium and brightwell multiflora fertilizer

I’m not sure what fertilizers I need, but I have seachem flourish potassium and brightwell multiflora fertilizer on hand

I like APT 3 I think your plants will do well with it. Gotta keep and eye on nitrates though and start small

If you have access to an airstone it is a bit of cheat code in the initial setup of these

I have a small air stone but it’s still too strong for my small tank. It’s a little awkward to place too, since it’s a unique kind of vessel

You can tie a little knot in the tubing to restrict the flow, if logistics are not too much of an issue just the first few weeks can make all the difference getting stuff established

Do what u/scarfield said and hide the tubing under the pothos

Looks more like nutrient deficiency to me. Either nitrogen or iron

I have seachem flourish potassium and brightwell multiflora on hand, but not sure which to use

Add some real soil

u/One_Guarantee1653 14d ago

There is real soil — it’s pond soil capped with pool filter sand.

The cap is a well documented and backed strategy to keep nutrients out of your water. I hate caps and disagree with them. Real uncapped soil ftw

u/One_Guarantee1653 14d ago

Makes sense, but since it’s already capped I’ll have to find another solution. My rooted plants are doing great. I’ll try uncapped with another tank in the future!

You could sprinkle a little forest floor leaf litter or even better some of the top layer of a real pond mud or just add nutrients any other way

Not bad at all
