  1. I meant if o2 is lower in the air intake.. in my last sentence. Sent from Singapore Reef Club mobile app
  2. I think both of you are saying the same thing. People tend to perceive the skimmer as a mechanism to inject O2 into the water. Thats not true. A skimmer enables additional gas exchange so that the chemical potential of O2 or co2 in the air intake is same as that of the dissolved gases in the water. So it is tending towards equilibrium. So if O2 is higher in the intake air, then it will appear as though the skimmer is reducing DO in the water. Sent from Singapore Reef Club mobile app
  3. If you have problem with PH first you need to check if the water in your tank is fully aerated. If the co2 in the surrounding air is high then even if your tank water is at equilibrium with the air outside, the levels of carbonic acid in the water will be high, which means more fre H+ leading to highe PH. This is rare in Singapore (unlike colder countries) we keep our windows open so the co2 levels in the air in your home should already be low (o.04 percent) almost. In this case if you scrub the co2 using media this will bring down carbonic acid in the tank but the effects maybe only temporar
  4. At the end its semantics, but shifts or trigger can happen at low or high organics. Good write-up btw, dont see anything other than classified posts on the forum, so this is great. Sent from Singapore Reef Club mobile app
  5. Yes thats my point. Does not matter whether organics are high or not for them to trigger. Sent from Singapore Reef Club mobile app
  6. You said dinos and cyanos decreased your ORP levels earlier ? Heres a study that phosphates enhance the growth of toxic dinos https://res.mdpi.com/d_attachment/sustainability/sustainability-12-04992/article_deploy/sustainability-12-04992.pdf Heres a study that shows uptake of organic and inorganic N on Ostreopsis- the kind that we usually deal with in our tanks https://www.researchgate.net/publication/316157113_Uptake_of_dissolved_inorganic_and_organic_nitrogen_by_the_benthic_toxic_dinoflagellate_Ostreopsis_cf_ovata Sent from Singapore Reef Club mobile app
  7. Okay want clear that it was just based your own ancedotal observation. If you looked at orp, you could also argue that maybr dinos/cyano causes reduced oxygen levels . In my case I have not seen that happening though. Activated carbon has had no impact on cyanos or dinos. Also aside from just correllation how would you explain organics causing dinos?

  8. This is not true. Where did you get the info that highrt organics trigger dinos, cyano and inorganics trigger brown algae? Sent from Singapore Reef Club mobile app
  9. Nopox is useless without a skimmer. Unless you do very large water changes. Sent from Singapore Reef Club mobile app
