I just want to give a update on my situation, and I'm hoping someone can help me out or advise me on what to do next.
So today I did a re-count on my CO2, and to my surprise my CO2 was running at 3bps
so I now know its somehow changed from the 2.6 I had it at, therefor I now know my regulator needle valve can not handle the pressure around 2.6 +.....
Before I had algae problems my co2 was at 1.8bps and I know it stayed stable there, and like I said I upped it to try get faster growths, anyway as of now I've turned it all the way to 1.5 and it's staying nice and stable but will keep an eye on it.
So what should people look out for when they adjust CO2, whether it be up or down, should it be done slowly toward your goal? or can you turn it up or down as much as you want, obviously people want to achieve 30ppm but should this be done slowly or what?
Also as Raymond pointed out in one of his tanks he doses Excel which when I hear about Excel its normally for low tech tanks to provide the co2... or to treat BBA etc, and in his other small tank no CO2 but light ferts...... So when should you use CO2?
Which leads me to this if you didn't already notice lol....I've set my CO2 to 1.5bps and not back to 1.8bps, I said to my self.... my plants are low light/demanding? so why should I aim for 2.6bps and add all the extra CO2, I guess I can only put it up so much before the algae benefits all the excess as the plants can't grow as fast and why would they take up all the co2, if there low demanding? in my case.
I also do use a drop checker so will keep an eye out tomorrow to see if it stays lime green throughout, I would also guess my co2 will now be at around 20ppm.... which leads me to my main question....should all tanks aim for 30ppm? if so why?
If I was blessed with high lights and plants that require high lighting and more nutrient demand, surely this tank would benefit from the higher CO2 levels (30ppm) and the system overall will work much better (Tank1). but in my case I went to around 2.6bps, which I now know wasn't stable... but most of my plants are low light, slow growers, mainly crypts, echindorus, so surely if I was at 30ppm my tank would not benefit as much as tank 1 would? Hope that make's sense. I've probably got this all wrong but hey.....
So my tank a 200g is pretty to large to start dosing Excel, I've got low light, low demanding plants, should I even use CO2? I'm nearly overstocked with fish, so the CO2 could come from here?... I wish I had more demanding plants but I don't, Yes I have purchased some plants that require more lighting around 0.5wpg, and in my tank there growth is pretty poor and it takes months, example Lileopsis has done nothing since I planted it, my glosso has not done much.
Will my tank benefit just as much, if I keep the co2 around 20ppm? I can only presume its around there tomorrow, or will I see problems? Should I even use CO2???? for my plants? and just dose my ferts instead? my girlfriends fluval EBI, has no ferts, no co2, but yet her plants still grow, slow but they grow, and mostly stay algae free, before I knew about CO2, my plants grew in my 90g... but like everyone on this site, I want to grow plants!!!
and give them the good stuff they need.
So maybe because of my lights, its best for me to keep it lower on the CO2? or stop it all together? I really want a tank that Tropica would be proud of, or even a tank Tom would be impressed with lol, but I just don't think my tank has the correct set-up, aka the heart, the light power to drive my plants.
So any advice on this would be great.... and most importantly what you would do with my tank?
Sorry If I've got it all totally wrong, and that the lowest light plant demanding tanks need the same CO2, as the high end tanks. I just am not sure and I've read many articles in the past and don't recall any of this being mentioned, sorry if it has.
Also one last question to throw in, how do I lower green spot algae on the glass? I pretty much guess everyone gets it??? it does my head in, and makes my arm ache! I do it every week, but it still gets there.
Think I've about covered it lol, and one day I will buy a rimless tank, and purchase the highest, most brightest lights out there, then get the distance correct as I don't want algae on that future tank and then purchase the fastest growing plants in the hobby
, but for now I cant
I have to make do with my new 200gallon and Eco Complete, that didn't come cheap either lol.
Thanks to anyone if they can help or offer there advice, I'm also considering on removing my carpeting plants, I tried my best with what I had, but there never going to grow at the speed I want or give me the carpeting effect, so maybe I should try some more crypts, stems or find some plants I've yet to try.
