hello 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
