This would be my first saltwater tank ever. Before I decide to tear down my cycling 10g or 20g plunk down money for rock, wave maker and salt mix, I have some questions. Coming from planted freshwater.
I have a 20g tall and a 10g currently filled and cycling them (for freshwater). I got them dirt cheap used but the lights aren't plant worthy. Looking for lighting ideas, I stumbled onto the topic of planted reef and I am quite interested. I'm considering a RODI
unit anyways for all my tanks. My water seems to suck.
I know to use RODI
water for salt. I will hit up the LFS
for a couple months til I can either pick up or build a RODI
I'm looking to stay on the easy side of macroalgae and corals. Although sea grass would be awesome.
Lighting has me sort of confused as antinic lighting is used in reefs. I'm wondering if a dual T5HO fixture (with reflectors) is going to be enough with a grow bulb and one antinic bulb or if it's even a good combo. this would apply to either the 10g or the 20g. I'd also like to be able to run lights for the coral/macros, but i'm also curious about adding some dim led
(or whatever) to be able to view the coral at night also that wouldn't encourage microalgae to grow.
As far as I can tell, I do not need to worry about co2
dosing with planted saltwater. Am I correct?
Then about dry rock. Rule of thumb seems to be 1lb per gallon at a minimum. Some stuff I have come across suggests that with macros I do not need quite as much rock. So I'm wondering if I can get away with closer to 15 lbs for the 20g or around 7-8 lbs for the 10g
