Hi, Ryan! I'm also glad you're here to helphello victor
im glad you did you read my thread about the glosso. wow that was along time ago. back then i had loads of proplem i just went straight in to high tech. lol
anyways there a few thing you have to do first beacuse the tank is so big.
you need to stop using the drop checker they are only there to tell you that there is co2 in the water. ph metre is the is the key and you want to aim for a 1 point ph drop. this is what work for me and always work for my other tanks but my water is hard like 7.6
like jose said get a ph metre and play around with co2. try different ways like co2 stright in to the filter or diffuser under the power head etc. co2 in my filter is what i using atm
can you give me you tank size? also your tap water ph and ph in your tank just before co2 comes on? you said your ph is low maybe beacuse you injecting too much and it doesnt get all use up in the morning. i had low to medium surface movement but after lights out i had my eheim skimmer comes on to get rid of co2 ph back to 7.6 before lights on. i use to have it on all day but with that on my ph won't drop anymore that 7 so i try it with out it and my ph drop to 6.7 which i get a 1 point ph drop.
if your tank was mine i would also change your light to x2 t5.
and about the glasses leaf that normally with glosso. its a new leaf and then turn darker once it get bigger.
remember when you change something be patient. test it for a few week before you make another or else you will run in to trouble. changes don't happen in a few days lol
when you get this sorted i bet you don't want glosso nomore beacuse you only have it in a small area and that area will take over your tank in no time hahah i trim mine and 2-3 weeks and full carpet again.
here my tank.
ada 60
eheim 2075
eheim skimmer turn on after lights out
ada substrate
high led with dimmer
i was using ei but had trouble with green spot algae and since i change it to topica specialised and now it all work fine.
if i miss anything just let me know
cheers

. I did a search about problems with glossos and glassy leaves in whole forum so I found your thread . So your problem wasn't excessive flow? Only a CO2 issue? My tank size is 200 cm x 40 cm x 45 cm (hight) and about 300 L of water. I'm using 6 x T8 with good reflectors so I have high light? I'm dosing 2x EI index. I have took a sample of my tank water and shaked it a lot to CO2 outs. After that I've measured the ph and the result was 6,8. I think my tap water has the same ph (I'll confirm after). My tank ph when CO2 comes on is about 5,8 and when it comes out is 4,93. My surface motion is weak to moderate. I don't use a skimmer and I got an annoying surface film that never leaves. So, should I use a skimmer or it's not necessary? Thank you.This should get better with time but a skimmer can help. You should balance whats worth it for you because you are starting to have a lot of things in the tank. I think maybe with time and water changes that surface scum will go.

my proplem was too much flow and not enough co2. its hard to get the right balance. im not sure about t8 in a 18inch high tank. i would use t5. eheim skimmer is great pieces of kit only £20Hi, Ryan! I'm also glad you're here to help
But I have 3 lines of T8 over the water surface and each light tube has a good reflector. My photoperiod is 8 hours a day but I begin the 2 first hours with only 2 light tubes turned on (the central line). I think I have high light, or not?

I'd have thought that was enough light but why 2 x EI? Surely the whole idea of a single full EI dose is non limiting nutrients as based upon high growth in a densely planted and very bright tank so to double that in a young tank makes no sense at all?

Well I have no experience of running a tank like this with overdoses of everything.
It makes no sense to me. I'd back everything off, light, flow, ferts, the lot and let things establish well before gradually raising them up again.

I'm using a ph probe. And the drop checker I dissolved some baking soda in a sample of water to do a 4 dkh water. After that I've tested the hardness with 2 different brands test kits. One told me that water had 5 dkh and the other told 6,5 dkh. So I think I have at least 5 dkh at drop checker water

I think 2x EI is just to carpet bomb shock and awe and remove ferts from the equation. If 2x EI doesn't resolve the issue, then its likely not a fertilisation issue. I remember one of Clive's tanks where he says he had to dose 2-3x EI to maintain plant health and growth. If 2x EI does resolve the problem, then there may have been issues in the original calculation.

That's a bit of a blunt instrument....

How about 1 tube 8 hours, 2 tubes 6 hours and 3 tubes 2 hours?

It is. EI itself is a bit of a blunt instrument don't you think? In my opinion, it was designed that way to minimise complexities for the new aquascaper.
I can't use only 1 tube or 3 (odd numbers) because I have 3 lines of T8 tubes, each one with 2 light tubes. So I think it's better to only turn on the central line during 8 hours a day.

Hey Victor, you can remove the tube completely to run an odd number tubes!
