I love Sanjay right, but 4min n 44sec in right and I must have heard the word 'right' 555 times already right. Enough already, right. 😮😂

@hugosandro 7 месяцев назад

Lmao. Same here. Sounds like someone else close to the mic. The club music doesn’t help either.

@brianjeffries207 7 месяцев назад

Totally agree. Couldn't even concentrate on the content as the rights were ringing in my ears.

i was wandering about that , i thought maybe somebody else was right …like somebody telling him to go ahead . Somebody typing or recording the speech

Excellent presentation on nitrates, I love the slide examples he drew up

A couple of errors in the first 10 minutes re:the Refield ratio. This was work done on phytoplankton, not corals, or bacteria or cyanobacteria. They all exhibit a different ratio than 16:1. For example, corals are 50:1, bacteria are 10:1, cyano is 5:1. Secondly, he left out an important difference, yes the ratio is NO3-N:PO4-P but it is not as simple as merely taking your NO3 or PO4 and converting this to N and P then dividing, because these are mass quantities and the Redfield ratio is a molar ratio, not a massic ratio. So when you read the scientific literature on N:P ratios, these are molar ratios being discussed. To convert your NO3 and PO4 values into a molar N:P ratio, it is NO3 (mg/L)/PO4 (mg/L) x 1.53 = N:P molar ratio. Interestingly, his conversion yielding ~10:1 is the correct massic ratio, but he does not explain how he got it. So 16/1.53-= 10, hence his 10:1 NO3:PO4 ratio.

Thank you Sanjay for the great info 🍻

Who is saying right after each sentence?😡

@simonlockley-evans3925 4 месяца назад

I've also been in the hobby 30 years, what all these "experts" fail to grasp is the basics when we talk about No3 and Po4. Our tanks do not represent the ocean, our tanks mimic a coral "colony" coral colonies in the wild are huge, you know what the purpose of the structure of a coral colony? Its to slow down water! Why? In lower flow you get nutrient build up, within the colony the No3 Po4 ratio is 100:1 its here, within the colony that symbiotic microbes can grow and reproduce, creating an oasis in the desert. The coral then farms these microbes and can even release hormones that give them specific instructions and can turn on/off specific genes within bacteria. Our tanks are not a microcosm of the ocean. It behaves as a slice of a coral colony does in the wild. When you think about this it makes perfect sense.

Who is this guy saying right and right?😂😂

@AllanAdajarMDFACOGFACS Месяц назад

Great talk Sanjay…but I have a question regarding diluted alcohol for carbon dosing. If alcohol and water doesn’t mix, how are diluting the solution, so it doesn’t separate in the dosing container?

@acanskywalker5631 6 месяцев назад

I'm sure Sanjay had no idea Tourettes Reef guy was in the audience.

My fifteen gallon AIO tank had off the chart PO-4 but very little algae, just a bit on the glass so of course I started chasing the numbers, now my PO-4 is very low and my glass looks like a fur coat.

@Baking_Baker 2 месяца назад

Great representation but please stop saying right after every sentence 🙄😤

@siggyincr7447 7 месяцев назад

Great summation of the topic. Only thing that I think might have been a bit misleading is the topic of water changes. Yes, one big water change can get your levels down with less effort. But the inputs and processes of the tank don't stop adding nitrate to the water. If you graph what nitrate levels would be over time assuming constant input and the same amount of water changed over time but at different intervals/amounts you find that smaller more frequent water changes will get you the same max levels without the big fluctuations. Sanjay even said right before saying that big water changes are more effective that you shouldn't be dropping levels fast. To me, the best water change method would be two dosing pumps one removing water and the other dosing the same amount of new water at the same rate. Yeah, you'll never get your levels down real low (which Sanjay has pretty much shown isn't necessary) but you'll keep things more steady, which is far more important.

Hey Sanjay, what are your thoughts on using zeolites for nitrate control? Supposedly it absorbs ammonia stopping the conversion to nitrate. I never tried it on a larger system, but I threw a sack of zeovit media in my nano and the nitrates stayed very low after my water changes. Curious if you have any experiences either with it. Thanks.

Would love to hear this but i can’t deal with the club music and commentator repeating “a’right” every few seconds lol

Such a shame the audio is struggling to compete with the music. Sanjay deserves better!

I thought the content was interesting, but I couldn't listen for more than 10 minutes. It was just too painful. Would it be possible to edit the video, removing all the "right" comments?
