As those of you who followed my thread you may remember that I had my freind look after my tank for two weeks while I moved and all my plants pretty much melted away. I managed to save a few.
Anyway, since setting it back up again I have noticed a lot of bubbles forming on the water. The worrying thing is is when they clump together at once end they look like a form of scum. It doesnt seem to have affected the fish but I am wondering if any of you guys would know what this is.
My water parameters are all the same. I have just started adding DIY fertz today but it started happening about a week or so ago so it is not that. The only thing that is different is I have started adding Hi Tech Co2. I got the Co2 from a reliable, well known company who assured me it is food grade, pure Co2.
So being that that is the only change I am a little confused. Oh I did get another bag of substrate and I didnt wash it first so I thought it might be that but I mixed that well with the substrate thats already in there and while it went cloudy at first that calmed down a long time ago.
Anyways I have added a few pics to see if any of you guys know what this is.
