Hello everyone, I'm new here and to planted tanks in general. I've been lurking around this forum and soaking up as much knowledge as I can before asking any questions.
I have a 5 gallon Spec V tank that I just recently added CO2 injection to. I am using Eco Complete substrate topped off with Black Diamond blasting sand (really fine) with some flourish tabs buried. It is a really basic setup with some dwarf 'mini' hairgrass and a driftwood 'tree" with some Christmas Moss attached. Nothing fancy. I'm pretty much just using the CO2 to help the DHG carpet a little faster. I get a fair amount of dust algae on the glass as well as some green string algae on the moss, the tank is still a bit new at 6 weeks. My concerns are the recommended dosing for Seachem line of ferts, their macros in particular. They seem very conservative, even for a low tech tank. I plan to switch to dry ferts using the EI method after I finish these bottles off but for now I'd like to use them up.
As for the stocking, I only have a male Betta and a few nerite snails. My nitrate reading typically only shows around 5 ppm. As for plant health, the DHG is sending out runners and growing okay but it looks sort of pale in color. I read that this can be from transitioning from being grown immersive.
I just wanted to get some opinions before dumping a bunch of liquid ferts into my tank. According to the Seachem dosing calculator, I should be giving my tank about a capful (5ml) to raise from 5ppm to 10 ppm nitrate, whereas the instructions on the bottle itself recommends giving it about 6 drops (less than half a milliliter) per dosing on a tank this size (~4 gallons of water). This seems like a huge jump. I'm aware it's not based on EI dosing on a high tech tank... but still. Seems extremely low. Is this assuming a heavily stocked 'low tech' tank with barely any need for additional nitrate?
Also, should I gradually increase fert dosing being as I have been running so lean the last few weeks?
Thanks in advance and Merry Christmas
EDIT: Phosphates tested at 5 ppm as well. This could explain my algae.
