Folks, if you've recently upgraded or renewed your annual club membership but it's still not active, please reach out to the BOD or a moderator. The PayPal system has a slight bug which it doesn't allow it to activate the account on it's own.
If you're trying to strip your water of PO4 thus stopping the growth of cyano, your corals will suffer first. So it's not a good strategy.
A proven strategy is to keep the nutrient levels, NO3 and PO4 at around the redfield ratio, about 1ppm and 0.03ppm.
As for your cyano outbreak, use chemi...
I think one prerequisite for keep these type of creatures is the ability to culture photo, pods and mysid shrimps. Mysid shrimp is like 20 cents each you know how small it is...
Yeah my potassium number is pretty solid :) @saltkreep88 I too was hoping something was wrong with the level so I could fix it.
My red is actually pretty good right now. But green is not dark enough but then again I have nothing to compare to. The green slimer is yellowish so is the paletta...
Congrats on the big upgrade. Looking forward to seeing it in action.
Rough estimates it's about 500g. I will generally shoot for 3-5 times turn over which means 1500-2500gph for your tank. An 1.5" full siphon should handle it easily.
As for overflow boxes current trend is to have a very slim...
I would get a 20g and a HOB filter for a classroom setting. So much easier and it will be more fun. Like mark mentioned an ATO will be important though in the classroom you can have kids taking care of refilling. I can donate a heater, rocks and a few easy corals. You probably don't need to...
Well we all have a lot of dead corals :)
I would say you have a very slim chance of keeping an anemone alive in a 6.6 gal aquarium. The easier corals are zoas, polyps, leathers and acans. Although polytoxin might be of concern.
Maybe some people here with nano reef can chime in on what the...
If you have not used gfo before it might strip you water too clean. So be careful with that. I would not use gfo as a long term solution. Carbon dosing is easier to implement and more flexible.
As for whether the algae will go away, it's hard to say. When your tank is balanced algae should be...
