I disagree, though the light might drive that deficiency.

HD, Yeah i added 1 new 85 GPH power head in addition to the 2 running plus my filter is pretty solid for this size tank Finnex px360. 13 gallon shallow.

The C02 was blowing directly at them with a yellow green Drop Checker, Im diffusing from the filter so im getting totally disolved C02 with a few spits every 3-4 minutes, so im stumped with co2 thing and starting to think that its the light itself??

@ThatGuywiththefishhY

Yeah thats why i originally raised the lights to lessen the demand and then uped the C02 in hopes to equalizee things.

Ug is spreading fast, Downi Helfari is spreading fast and E.Parvula doing great,
Glosso on the front right started as a hitchiker is doing well along with mini fissidens etc, Just The Staurogyn is struggling under this light!!

that looks like very low lighting to me. is the light in your emmersed tank closer to the repens.

final awnser l i g h t.

I found that Staurogyne is quite versatile to water parameters but one thing it doesn't like is sudden change. I had two bushes that melt in the time span of one week after a gH abrupt change. They disintegrated completely. CO2 and light do not matter much. I have some that grew in almost no light being planted at the base of a huge Althernantera pack.

Curly leaves makes me think there's a Ca deficiency. This plant grew well in gH higher than yours. I don't think that's the problem but the test doesn't tell the whole story. It might tell you how much bivalent ions you have in the water but not the proportions. The gH test might indicate some other ions and you have low Ca or none.

Those water changes might be the culprit here. If they bounce water parameters this plant could be affected. Others might have alternate ways of getting their fill but this one not. One thing I observed in my tank is that light does not have a huge impact. It grew slowly as usual in both high and low light. Flow also was not available to it as I lost all my Downoy and this plant survived.

Hope this helps.

my kh is 2 and gh is 4

i personally have downi and repens and hc and i use flourish and api iron and potash. no root tabs also co2 a 1 bps in a 40 gallon with a ceramic diffuser.

i also have 6 23 wat sprial cfls 3 inchs above top lip of tank.

if kh is calcium then you have more than me. yet my hc is not melting my repens is short and really full nodes are a 1/4 inch between them is not curling and my downoi is doing great

i really think bringing you light down is the awnser maybe lower to 1 1/2 feet or 2 and keep everything else the same and see what happens

i also do 2 30 percent water changes a week.

hope this helps

Thanx, thats very good information. I too have read about people keeping S.Repens in very High/low GH and KH and low/high light, C02 and non C02 which is why it is so frustration. I consider this tank to be high tech.
I too wonder about the GH readings, I dose GH boost in Barrs recomended amounts and it doesnt affect the GH so im wondering if im getting readings of some other ions. maybe i can increase my GH boost doses?

Also great info, i suspected that the raised light caused the HC to melt, so i lowered it down to 2 1/2 for now and cut the photo period to help with the recovery, leaving everything else the same until i can grow my emmersed batches. Oh and yes the emmersed setup is very well lit and fairly close to the plants.

After reading this article im going to explore dosing 2x's the GH boost amount per WC and see what happens.

I grow a ton of this stuff, the comment made about change is likely the key there.

I cooked a tank and poushed it to 90F, that melted most of the leaves over the next 2-4 weeks, then 1-2 weeks after that, new leaves came back.

It's a bit like a Crypt really.

This has nothing to do with ferts, Ca++, CO2 only if things are bad for a week or more/chronic etc.

Try trimming the new tops and the bottoms will sprout new growth.
When you plant this plant, it does nothing for 1-2 weeks.
It's growing roots actually.

So it does not bother saving those leaves you have when you get the plants.
It'll just grow news specific to the tank.

My tap is KH:1 and GH or 2.

I dose about 1 teaspoon per 60 Gal of gH booster 1-2x a week.

It's nothing to do with Calcium, I've never seen any confirmed Ca++ deficient aquatic plants in my life. Well, Rice, but no submersed species.

@ Tom Barr
I got my first 2 batches from you and they both slowly died off over the course of say a month, this last batch i only gave it about 3 weeks before pulling most of them. So things seemed to be going south within that time.

I have left a few in the tank for test purposes, If they bounce back then i'll reintroduce the emmersed plants maybe cutting the tops prior to introduction..

Where do you buy S. Repends? I can't find it anywhere.

Tom Barr (aka plantbrain) is a great source.
