Tank suitable for Sps...

[Terryz_]

Actually is 3x150w Mh enough for sps...

Just remember this tip. Higher wattage MHs can penetrate a lot deeper than low wattage ones. You will get much better growth and colouration due to the increased intensity and UV.

Using low wattage MHs mean you have to place ALL your acros high up.

[Terryz_]

So even if i place the acro high up... growth and coloration wun be as good...

[Achilles Tang]

Ehhh... from my experience, all other factors aside like water quality and parameters' stability... that's 100% correct!

But if I were you, I'll invest most of my money on a very good skimmer, tunze streams and a calcium reactor with the lights as a last priority.

Water first. Lights last. Most people always think its the other way around.

I am spending more on Skimmer and Ca reactor rather than lights...

[Achilles Tang]

You're on a roll, dude!

Hope can get this tank right... I am planning to put my existing boxfish, flasher wrasse and sailfin into the future tank... Will they disturb the acro...

[Achilles Tang]

Boxfish??? These are not reef-safe fishes. It's a risk.

[Terryz_]

hmm... oh well... will leave them in the nano tank...

[Terryz_]

Oh... ya... one more thing is a kalk reactor also neccessary... Is there any shop that sell both the whole Ca reactor set with the co2 tank... Thkz..
