Hi guys, Not so much of a problem more a general query here. Basically I was having issues for ages with my tank & wasn't getting the growth I wanted etc. Finally I realised that I was messing with my co2 too much and too frequently - so my tank was unstable. So I have left my CO2 stable at...

Hi all, I’ve read some good articles recently regarding CO2 changes & enzyme production – noting that when changes are made it takes time for plants to adapt properly. I didn’t realise this previously & was constantly adjusting my CO2 (putting it up due to frustration with lack of growth – then...

Hi all, When my reg is hooked up & running the preasure gauge on it is not still. It moves very slightly up & down. Between 1.6 - 1.8 bar. I use a wave co2 reg. is this normal? I am beginning to think my co2 supply is not stable & could be fluctuating - is this an indication of this? Thanks

Probably a silly question & has probably been covered before... But... Does having more CO2 mean you need more nutrients? Or is it only light that drives the nutrient demand up? Or does having a tank with a yellow DC need more nutrients than one with a Green DC? Just wanted to double check

Hi, I have a question about the CO2 concentration in tanks & the light demands that follow it. Does the CO2 work in the same way that ferts do - in that the CO2 uptake is capped & that upping CO2 will just mean that the CO2 will not be a factor in limiting plant growth. Or Does CO2 work like...

Guys, Is it safe to do inline CO2 - but have the CO2 diffuser running on the intake rather than the outlet - on the Cristal Profi E1500? I hear this is the best way to get CO2 into the tank but I am worried about leakages & also lots of burping from the filter? Has anyone ran this set up with...

I'm sure they don't mean much... Mines always yellow & I dose EI yet I still get algae and slow growth. Something can't be right there - I also have like 20x turnover in my tank.
