Ph Gone Down

[DJ ArKaDaRkA]

I'm guessing the low pH is caused by the still cycling tank and the relatively low WPG you're using. At low lighting (~1 WPG), you really don't need to inject CO2. Especially at a high rate. The plants just don't use it up that fast since the light level is more rate limiting.

I would say that those 2 factors are contributing to the low pH. It is not a huge issue though, as your current pH is fine for your fish. You may want to check the pH before lights out, and after they come back on in the morning to see what the daily swing is. It should not be too high, but a couple tenths is fine.

If you just added fish or changed things, you can cause a mini cycle. It can happen regardless of how old the tank is. It's not abnormal. Just monitor the ammonia and nitrate levels and do water changes as necessary to keep them in check.

ok will do yeah i added a gourmai and cory together one week then the week after a rainbow shark do that probally the reason

i might sack off the co2 for now?

if these plant do die im not going to get anymore im just going to get a few silk ones and have a more rocky/cavey looking tank like a desert or something

i think i was a bit hasty think i knew best when i bought the tank so ive only really got myself to blame for this mess

Yes, it could be that you could stop with the CO2 temporarily until your filter is more robustly cycled and then come back to it. This might help your cycling process.
