3 macro IDs please

[gemini aquarius(t)]

ok well i have had these three macros for a while in my tank and i dose iron for them every day and it seems to keep them happy so i would like an id on them thanks!!

first a dark red macro

heres another shot of it

and then theres this one there is some detritus on it but im not ready to brush it off and possibly loose some of the macro

and hers the last one (there might be 2 kinds there im not to sure)

The first I think may be Rhodymenia

The second I cant see well enough for a guess, and the third there just isnt enough to tell, but possibly some type of Caulerpa.

If the bluish one is like this:

it's probably Ochtodes. Another name, mentioned only once, was Hypnea spp pannosa.

The last one, judging by the bottom leaf, could be Caulerpa taxifolia.

yep thats what it looks like

Ochtodes, IMHE, grows even under low light (the fluorescent bright blue on the photo - under 18W (50% actinic, 50% 10,000K) PC, plus an hour of sun), under 6,500K (daylight bulb) 27W - was dull blue-green-grayish. This is for 6g tank. No special requirements, as far as I know.

Caulerpa requires more light and didn't wanted to grow in my tanks.

well in my tank i run my 6,500k lights 24/7 its only 28 watts or so but i have caulurpa so i dont want my tank going sexual i think it killed the blue stuff though and after the fact i relized it probably doesnt like much light but im pretty sure its gone so im kinda sad but i need to find a way to get more cool stuff like that!

Pity... If some branch survived - it may regrow again.
It seems to me, that Ochtodes just tolerates low light, because I have it in another tanks - under direct sunlight and other under 27W 6,500K spiral bulb - no problems, grows as well. These are display tanks, with photoperiod 11hrs day - 13 hrs night.

ohh well that ruins my explanation for why it withered away any other ideas?

 

[dendro982]

Most likely I misunderstood, but are you keeping lights on main tank 24 hrs? Or algae was in refugium? Algae, other than caulerpa, and corals usually need time to rest from photosynthesis (other processes are taking place). Also, you may have very clean water (mine is not). Hard to say, could be anything.

ohh it does? well then what is the bast thing for the tank cause it has corals fish and algae and caulurpa??
