I have watched them all, some of them twice.Sounds like time to binge watch Tidal Gardens on youtube for the species spotlight episodes!
Perhaps some one can help me understand this, every couple of days my tank's ALK just plummets and i don't know why.
No more than usual. It happened yesterday and there was no one at the house at the time.Do you have lots of people in the room every couple of days? (Maybe CO2 build up causing carbonic acid to drive down the alk level?)
Yes, but I’m dosing 20ml of nitrate a dayIt's strange that both your alk and phosphates are both bouncing around. Is this happening with nitrates too? It might be best to leave things alone for a few weeks and see if it helps stabilise your system's levels. Maybe your adjustments are not giving a true reading before you adjust back the other way each time.
Thanks, I'm struggling with keeping nutrients in the tank, and I was worried that was the cause of them turning brown. As of last night have started dosing Kalk back to the tank (Just at night). The PH is dropping down to 7.4 at night and doesn't even make it to 8 during the day. I know this is due to the Calcium Reactor, however, I want to see if I can compensate for it.Sorry to hear bud. As far as how long the corals stay brown, it really depends. In my experience if you can keep things stable corals will start coloring back up in a couple of weeks to a month. That is assuming no other major fluctuations/mishaps.
I also would t worry too much about them going brown at this point. While they aren't the prettiest to look at, many corals turn brown and then slowly color back up when being introduced to a new system. Give them time to adapt to your system/lighting/nutrient levels/maintenance schedule. They will color back up in time.
Thanks, I have even recruited the kids to help out with the tank. My youngest daughter does the nitrate testing with Dad's supervision, and my son feeds the fish. He now wants his own aquarium in his room with his fish. The scary thing is the wife is actually open to the idea. I told her we have the 90-gallon tank still sitting in the garage, and she agreed that would fit in his room.Sounds like you are making progress. Not sure why you are having so much trouble getting nutrients up, but keep at it. If alk/cal consumption is up, then something is using it.
Keep at it. You will get there.
Yes I test the additive and it was well over 50. Right now nothing but filter socks that don’t change until they are over flowing.That is a lot of nitrate. Are you dosing neonitro? Or a different form?
Have you done a test with your nitrate additive and dosed it into a known volume of saltwater and tested to make sure it is raising it as expected?
Not sure what your total system volume is, but 300ml of neo-nitro is 5ppm in 300 gal system. Not saying it isn't using that much, just is a lot.
What export methods do you have? Fuge? Skimmer? Carbon dosing?? Maybe try turning down some of the export methods to try to bring the system back in balance.
