  1. You only need to add small quantities everyday and you should be fine. Then the salinity or ph dont affect given overall water volume. Sent from Singapore Reef Club mobile app
  2. No its not the same. You dont have control over how much phyto you dose with an ato. It just depends on your rate of evaopration. On a hot day you dose more etc. dilution of that one bottle again depends on the size of your ato reservoir. With a doser you chose to dose 5 ml everyday for example...

  3. All marine phyto are grown and sold in saline water. So dosing using ATO will increase salinity and defeat the very purpose of an ATO. If you want to dose get a cheap doser. Sent from Singapore Reef Club mobile app

  5. What is pretty low? What is your current KH value? Yes test on the same time on consecutive days without any dosing to find out your daily Alk consumption. Sent from Singapore Reef Club mobile app
  6. My question was not about whether you should qt or not. Why do you need to dose? Do you know what your daily Alk consumption is in dkh? If you dont know the answer you should not be dosing anything. Your fresh salt water mix at whatever salinity you desire ( say 1.026) should already provide adequate Alk, ca and mg levels. Lets say you use the red sea blue bucket salt - at 1.026, your alk should be around 8.5, ca around 420 and mg around 1350. Now if your daily tank dkh consumption is .2 dkh, then your Alk will fall from 8.5 to 8.3. So you add all for reef to make up for that deficit And
  7. Why do you need to dose in a coral qt? Sent from Singapore Reef Club mobile app

  10. Close the air intake completely and then crack it open very slightly. You probably are letting in too much air. Pm if you need more help. Sent from Singapore Reef Club mobile app
  11. Great thread and post. We all know that viruses and bacteria exist on every coral. They actually make up the holobiont, but they are really separated from the coral tissue by the mucus layer. So it becomes a problem only when the mucus layer is breached due to some stressors. That gives pathogens access to the coral tissue which could then translate to RTN/STN. One of the things I am very keen to understand is how DOC ( especially from algal photosynthates) impacts this mucus breach given other stressors (temperature swings etc). So in a high DOC environment, due to increased bacterial ac
  12. I meant if o2 is lower in the air intake.. in my last sentence. Sent from Singapore Reef Club mobile app
  13. 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
  14. 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
  15. 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
  16. Yes thats my point. Does not matter whether organics are high or not for them to trigger. Sent from Singapore Reef Club mobile app
  17. 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
  18. 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? Sent from Singapore Reef Club mobile app
  19. 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
  20. Nopox is useless without a skimmer. Unless you do very large water changes. Sent from Singapore Reef Club mobile app
