Help me pull through...

[11panos04]

This is the program i made,by myself,please help me,if i m wrong.I ve been using it for a couple of weeks. Hygrophila difformis and siamensis are almost completely destroyed,i don t know what else to do...
Light is led (white-blue) 700lm 6hr/day.

Special nutrition says is all macros and micros, flourish is only micros, k is potassium and c is carbon.

How long has the tank been set up/how long have the plants been in there?

Water parameters/temperature? Tank size? Tank mates?

Neither of those plants require anything special to grow, which is odd that they are dying off given extra nutrients.

With that many nutrients available, have you tried increasing the light hours? 6h is pretty short in my opinion anyways, of course if this is a new tank it’s wise to keep the lighting hours down to avoid algae blooms. But if the tank doesn’t get much ambient light, there’s not too many plants on this earth that are going to thrive on 6h a day of light.

Its been up and running since 13/11/21, most plants added a couple days later.What information do you need exactly? Τested with liquid tests O2 is ok(with little surface agitation), ammonia is 0 and NO3 is 0. It is 36lt, 2 ottos, 5 red cherries (used to have one betta as well).

Basically any information you have. Never know, one thing might stand out to someone and not someone else!

No nitrates? Are you doing an extremely large water change every week?

Anything special in the substrate or is it just fine gravel throughout?

Those should be a “grown anywhere in any condition” type of plant. But sometimes they’re just duds! I’ve got a dud Alternanthera reineckii right now that just refuses to do anything while all the other plants in the tank are basically exploding.

We’re these plants grown immersed or emersed? (Did they ‘melt’ shortly after planting). I don’t know if these particular plants do it, but apparently it’s true, that after so long of a growing cycle immersed the plant will basically go dormant. I’ve seen something similar to this in my ~8mo old 29g tank. Some of the original ludwigia I put in there went dormant for close to a month, meanwhile the 1-2 month old replanted trimmings were still going strong in there. A bunch of them looked like they were near death for the longest time and over the last week or so I’m starting to see a bunch of new growth on them finally.

So sometimes all we can do is maintain the conditions we are in control of and sit back and hope that things turn around.

I don’t get too crazy about fertilizers and honestly think maybe you’re going overboard for such low tech plants. But to each their own. I use seachem flourish and iron in my tanks, dosed after weekly water change on the 29g and 2x a week on the 75g (usually only change water every 2-3 weeks in that)

Ι used to do 50% w.s.,to be exact,but from today i dropped it to 30%.Will it be ok,if i put some fish food in a small net bag and that in the hob filter,so that i can change it it every 2 days or so,just to increase nitrates???I had problem with some worms recently,i have some shrimps now and 2 ottos,they don t eat too much,i am afraid if i start dropping food freely in the tank,they ll stay on the bottom and worms will reappear.

If your gh/kh is good, I would just forego some water changes till the nitrate levels come up before I started throwing food at it. I don’t know if putting it in a net in the filter would work, I’d think it would eventually break down and end up in the tank anyways
