I use flourish excel and it seemed to help my non rooted plants like hornwort, java moss, and floating plants at the surface. I've never tried c02 because I don't need it. It's all preference I guess.
It's generally not very nice stuff so the more sensetive plants will suffer. Bladderworts and some species of Vallisneria.
Overdosing is a no no and lots of things suffer then.
It can't beat gas but its a good alternative as long as the tank doesnt have megawatts of lighting and its huge. I'd choose it over DIY yeast CO2.
minnnt, you're dosing TPN+ which is good but too many folks are getting these liquid carbon products and not realising that they need to dose extra macro (and micro) nutrients and do large weekly water changes. They wonder why their plants start dieing.
Right. Thanks. I'm doing 2 25% weekly water changes. My vallis has always done well and can't say I have noticed much of a diffrence with that, but the java fern, crypts and swords look great.
Yes. Keep up the nutrient dosing and large weekly water changes or 2x25% like minnnt.
If liquid carbon products are being used, then they should be used daily.
Correct. If anything you'd make things worse if you used Excel on its own. The plants metabolism would increase but the required nutrients that the plants now demand would not be there so the plant would break down. An unhealthy plant system = algae.
TNC complete is good
TNC complete is an all in one fert. Macro and micro nutrients. See here.
TNC Lite is just trace elements/micro nutrients (that's what Flourish is). See here
