I saw a purple one with yellow polyps a while ago, I regret not picking it up. Its going to be a nice seahorse tank. :clap:
Had to decide on something, and went with what I knew had worked in others' tanks. Because iron is needed in such small quantities, I'm gambling that it can be supplemented in other ways. It may come back to bite me, I'll just have to wait and see.slipknottin said:Eh, wish I could help you with the living seas, I was just there, but didnt pay particular attention to the seagrass/seahorse tank.
Why did you chose an aragonite instead of a substrate like fluorite? AFAIK, marine grasses will pull iron (among other things) directly out of the substrate.
Alk and Ca++ are huge issues.
Yes, you can do EI on a smaller marine or a reef tank, weekly 50% is not bad on a 15 gal tank.
You can extend things out to 2 weeks as things settle in.
I dose roughly 3-4ppm every 2-3 days and PO4 at 0.2ppm at those same times.
This is for a densely planted Marine tank.
Traces, Ca/alk can be added liberally.
Aeration is your friend, a skilter would work well.
4" of aragonite, mulm, and well soaked mud(soaked for 2-3 weeks), about 1/4" or so on the bottom and mix with the arag 's first 1", then cap with 3".
