I did know you posted all the readings in the first post, I just always want another test done!
I assume every other day is what you're doing now until you get some proper movement of the readings?
Yeah a peacock cichlid gets massive, and will eat everything
Very cool in a massive tank with other monster fish but IMO you lose out on keeping other smaller interesting fish if you have one. It certainly wouldn't go into your 125 or my 5ft'er long term for that matter.
If you want rams I would go with Bolivians as they like a middle of the road pH and temp which lots of other fish fit into as well...blue rams need a higher temp and lower pH which means your tank would not be able to take on too many types of fish...although discus would go and do look very impressive. I tried keeping blue rams when I first started which I now know was a big mistake, the pair died because the tank although cycled was just too newly setup, plus the pH was too high really.
I am a bit mifted about how cloudy the sand became, I washed it for 2 hours again today before putting it in...it's getting there and I have to wait for the temp to come up yet anyway...almost 20C now, risen 6 degrees in 4 hours
I'm happy with the colour though, I thought it was a tad too dark but I like it under lighting, it's just more natural than the usual suspects - I want a natural looking tank for sure.
I think I might be moving the fish at around 11pm at this rate...still it wouldn't hurt to wait until tomorrow morning
