Hey thanks for the replies everyone,
Yesterday I removed all the infected leafs, I've got my 50% w/c day tomorrow, so will do all my normal routine, I will also most likely clean filters again around mid week, and maybe do a 25% w/c as-well, if that will help things as mentioned by plantbrain, I presume this it to remove even more organic waste from the aquarium?
I will also keep a close eye on things and make sure to keep up on removing any debris etc, and most importantly concentrate on getting my plants growing rather then focusing on the algae issues, its annoying as I'm pretty sure everyone wants there plants to grow but when algae starts to appear, you can forgot about that, and then you focus on the algae lol. I know its always repeated on here that people say focus on the plant growth and co2 etc, but sometimes its quite hard, especially when your not very knowledgeable and experienced, but everything I have learnt has come from this site and Google, sometimes you need to be reminded lol
so thank you.
Like I said all I have done recently was to adjust the CO2, so this has kind of taken over my tank all of a sudden which I didn't expect, there are also a couple of things I'm considering on trying which might help that bit more and that's to buy some some root tabs just to give my substrate some extra nutrients and to give a extra boost to some of my root feeders.
I also remove lots of water lettuce weekly, but I think I will let them multiple even more like I use to, the more healthy plants I can get growing hopefully the algae won't grow as quick and hopefully I can beat it, which also makes me think It might be a good idea if I go out and buy some more fast growing stem plants.
I'm not sure what I can do to save my stauro repens, most of the plants are covered in the brown stuff, I did rub quite a lot of with my thumb yesterday but I cant cut the leafs, as there would be hardly any plant, I will try and get some more flow around them, and see what happens?
I also remember doing a large trim on both of my echinodorus plants which were the largest plants in the tank, so maybe this has made room for the algae to start appearing? as they were two of my fast growers compared to some of my other plants.
Another question as-well to people who use nano diffusers, or anyone with experience, surely if the diffuser is releasing loads of tiny bubbles and some as tiny as a stream of mist, surely the co2 must fluctuate a little bit? as when I watch my diffuser its obvious each bubble is not the same size, surely there sizes vary through the day?
Some bubbles from the diffuser are so tiny, you can hardly see them, it literally is a fine mist, where as other bubbles are quite large, and other small etc....
I guess I need a diffuser like the GLA one:
But I think they cost a lot of money, + I'm from UK. I do use a Rhinox 5000 though which many people here do use:
Sorry for the essay, and also my substrate is Eco Complete.
