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

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?

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

Nopox is useless without a skimmer. Unless you do very large water changes. Sent from Singapore Reef Club mobile app

Selling unopened box of Original tropic marin balling components a,b,c powders. Pm if interested. Collection in pasir ris. Price 45 sgd. Sent from Singapore Reef Club mobile app

Selling almost full Orca nitra guard titanium. No reactor required. Will reduce your nitrates without any dependency on Phospates. Sold as the only solid carbon media that is completely resistant to the redfield ratio. Definitely worked for me in reducing nitrates. The media should last you for more than a year with continous usage. Selling at 45 Sgd. pm if interested. Collection in pasirris. Sent from Singapore Reef Club mobile app

Selling Dr. Tims NP active pearls bio-pellets. Great polymer for reducing your nitrates. Almost full. Selling for 70 Sgd. PM if interested. Collection in pasirris. Sent from Singapore Reef Club mobile app

It is always about availability rather than residual levels. In the ocean nutrient availability levels are high - even if residual levels show low. Also depending on currents sometimes residual levels also can become high. Also, regarding sps needing low nutrients may not be very true. There are studies/ ancedotal evidence that shows sps growth is higher in higher phospate levels. What sps dont like is instability. So if you go from high phospates for some time to low phospates then that negatively impacts them. Same thing from low to high but to a lesser extent. Interesting discussion though.

You are right fish based proteins are better but more expensive. Plant/animal based proteins are usually deficient but cheaper thus being used. It also depends on what amino acids are available in the proteins. Some like methionine are supposedly more useful than others. Also whats interesting is how proteins are used for growth. When carbs/lipids sufficiently provide energy, then proteins are used for growth. When lipids do not provide for the energy requirements, then proteins are actually used for energy thereby stunting growth. A balance is important.

Bro, good write-up but needs clarifying. You are right about binders not adding too much nutritional value , but not about adding nutrients to the water. Binders used in pellets are carbohydrates ( starch, sugar etc). Some of it can be metabolized by fish for energy. But you dont end up with nitrates and phopates due to thhesr binders. Nitrates from food usually comes from the protein content. About 65-70 percent of the protein in the food gets passed through the gills as Ammonia ( more than 50 percent) and in poop ( about 10 percent). This ammonia then breaks down into nitrates. Choose the food that offers the most nutritional value. But the best foods does not automatically translate into the least nitrates/phospates. Happy reefing !!

Looking for a decent condition calcium reactor preferably dual chamber. Please PM if you are selling. Thanks Sent from Singapore Reef Club mobile app

At this point you are speculating that your tank needs any alk addition. You need to measure alk levels from a baseline to check actual usage. Then you can decide if u need to dose. And its usually better to keep your alk close to what your new salt mix is at - which is why I was saying to test your mix. Any level between 7 and 9 is just as good. I would get an ATO asap. Stability is key - not whether you are at 1.025 or 1.021. Sent from Singapore Reef Club mobile app

Okay start by checking the alk levels on the fresh mix. Your salinity must be low which is why the Alk is low. You can bring up Alk just by mixing it to 1.025 or 1.026. Sent from Singapore Reef Club mobile app

How frequently do you do water changes? If you are using red sea blue bucket your Alk should be much higher with only water changes given your stock levels. And what are you using to measure Alk? Sent from Singapore Reef Club mobile app
