That is true in some cases.
Some reefers define a lot of food as 1-2 cubes while others think 10-15 cubes is starving their fish.
In most cases, reefers today have good export method’s. There’s more tanks starving today than ever before. The problem I see more than anything is that some reefers just can’t stop feeding. Not only that, but they blindly feed without measuring what’s going in. That’s fine, but they need to have nutrient management under control first.
Then you have the flip side of that. Joe Reefer has a starving tank. He says he’s dosing NO3 and PO4. You ask how much are you dosing? He says 10 mL of each. Then you ask…what does 10 mL’s equate to in your total volume. He says…that’s a great question. LOL.
10 mL’s could be .000000000001 ppm or 100 ppm. Depending on volume it could be drastically different in 10 gallons vs 500 gallons. As soon as they begin to talk in mL’s and not ppm with their total volume I’m thinking here we go again.
