NanoRox Posted March 9, 2018 Share Posted March 9, 2018 My cheato reactor is functioning a bit too efficiently. My Nitrates and phosphates have been immeasurable for over a month and a half now and I am starting to see some of my zoas not opening completely. I think the issue is that the water is too "clean" and would like to see a slight increase in nitrates. Can you tweak the function of a chaeto reactor by perhaps decreasing the photo period?

HarryPotter Posted March 9, 2018 Share Posted March 9, 2018 decreasing photoperiod may just decrease the health of the chaeto. I would get rid of more- just keep a little bit growing at a time. Quote Link to comment
NanoRox Posted March 9, 2018 Author Share Posted March 9, 2018 Sounds good. I will harvest more of it this time. I would love to have lab quality testing available. I would like to see the rate of nutrient export as the chaeto grows and see if it plateaus at some time. I have been harvesting every two weeks when the canister is full so perhaps I need to thin every week. It's kind of a pain to do so I have been trying to squeak by every two weeks.

MedievalITGuy Posted March 9, 2018 Share Posted March 9, 2018 Maybe try swapping the chaeto out for a slower growing macro like Dragons Breath? Quote Link to comment
Subsea Posted March 12, 2018 Share Posted March 12, 2018 @Duane Clark I see no problem with reducing photoperiod. If you are trying to leave more nutrients in the water, harvesting more frequently, IMO, produces the opposite results. Even with thinned out chaeto, it grows faster because of better light penetration. Do you record pH? Curious to know what are normal pH fluctuations in a nano cube. https://www.wardlab.com/plant-services.php This agriculture lab is the best for plant tissue. They also do scientific accuracy water testing. Quote Link to comment

Subsea Posted March 12, 2018 Share Posted March 12, 2018 Before using chaeto reactor, did pH fluctuate during lights out. Steady state pH is not normal during lights out. The natural reefs in the wild fluctuate between 7.85 - 8.15 pH. At a pH of 8.1 aroggonite begins to dissolve. Do you drip lime water for alkalinity control? Quote Link to comment

NanoRox Posted March 12, 2018 Author Share Posted March 12, 2018 @Subsea I have not checked the pH at night actually. The Chaeto reactor light runs at night with about a 4 hour overlap in the day and a 30 minute overlap in the morning when the display lights start to come on for a total of 14 hours. I add kalk to my ATO - 1 1/4 tsp per gallon of RO/DI. Quote Link to comment
xiaoxiy Posted March 12, 2018 Share Posted March 12, 2018 I'm experiencing the same thing with my Chaeto reactor and decreased from a 12 hour photoperiod to 10 hours yesterday. In theory, this should decrease the Chaeto's ability to assimilate NO3 and PO4! Quote Link to comment

I probably need to start decreasing it. Quote Link to comment

I probably need to start decreasing it. Since I just did it yesterday, I have no words of wisdom about how the Chaeto will react to this. I know for a fact, however, that people sometimes only run 4-6 hour photoperiods and still get growth. Quote Link to comment

Currently my chaeto reactor is a combination of slime algae, chaeto and red gracilaria. All three are growing well, especially the slime . Quote Link to comment
