Thank you for the the information threw experience. Goniopora are quickly becoming a new favorite of mine. And its always interesting to learn and find out what works. It would definitely be something to see how they've grown in the future.

Alkalinity is running at 7.6-7.8 dKH.
Nitrates have been 6ppm.
Phosphates have been 0.04ppm.
I just did my first water change yesterday after going two months without one. I've been trying to keep my nutrient levels up so I had forgone the water changes for a bit. I have been dosing nitrates periodically to get them up to 6-10ppm as the ATS unit has been very efficient at removing them.
Here's yesterday's algae harvest.
Fourteen day cycle; 451g (hand-squeezed dry weight)

The algae harvests have been "impressive" for the last half a year.That's an impressive amount for 14 days of growth!
What do you do with the algae once you've pulled it?

The algae harvests have been "impressive" for the last half a year.
I don't remember who said it (but Sanjay or Mike Paletta come to mind) but good coral health comes from feeding heavy and filtering heavy. The trend has been to harvest about 350g of algae every two weeks. I've had two bumper crops and I can attribute those to when I do more broadcast feedings at night; and target feeding the Tubastraea.
I had been saving the algae in cups with the dates and weights written on them in case the study wanted more information for the research, but I just tossed them all out this weekend. There was also discussions with Bill about getting the algae over to Augsburg as a food source for the urchins, but it's not really feasible during this time.
When the algae is squeezed dry, it remains damp and doesn't have a nasty smell like it's rotting. So I wonder if it remains viable for a time after harvesting. I have thoughts about seeing if the algae can be saved and then used to seed new screens at a later date. I just don't know if the algae would respond with growth or decay when reintroduced to a wet environment. I do know that when we share algae with other people to seed a scrubber screen that we don't need to bag it in water. Algae submerged in stagnant water is when it decays and creates that nasty smell.
Good question.![]()
Thanks Jason for the post ! Am very tempted to attempt it but since I have no experience with scrubbers , haven’t pulled the trigger yet .Heavier feedings have consisted of an increase in frozen foods being offered daily. I don't know the exact amount, but it's like 1-1/2 Oreo's worth of frozen food per day. I have also added a pinch of PE Mysis flake food to the thawed foods. That amount of food is shared with the 32gal, but the Oreo's share going into the 120gal. Nighttime feedings have been about 5-10ml of Reef Nutrition liquid feeds 2-3 times per week. The targeted feedings for the Goniopora are now once a week with the recipe previously posted.
I dose ESV's Transition Elements (iron, manganese, potassium, etc.) to cover trace element supplementation almost daily. I also try to dose AcroPower daily. Once a week, I'll dose a small amount of ESV's Iodine to help keep the potassium level up with the montipora growth. And based on test results, I will dose ESV Nitrate to keep my nitrates above 6ppm.
Managing higher levels of nutrients has been a conversation point with ATS performance. Those that are running a scrubber on a system with very nigh nitrates aren't seeing much of an affect from the scrubber. There may be a threshold where an ATS cannot perform to its best ability until nutrient levels are within a certain range. It's all conjecture at this point as no real studies have been done. I have not had any problems with having too high of nutrients and I cannot compare my experience with those that are having that issue as we are running different scrubbers. I do know that I was able to pull nutrient levels down when my nitrates were around 32ppm; I've tried to not ever get above that level.
I would be very interested to know how the APIS series of scrubbers are performing in various systems. I haven't heard much from personal feedback except for a few posts showing algae growth on social media. They do say that you won't often get positive feedback, it's the negative feedback that people like to post; and I haven't heard much of that either.
