What structures do they host? Does rock formations count? Or will I need to get a soft coral in there early?

Hello Got a 400L tank. And I think about 100L sump. Maybe 80L. Finally putting rockwork into my new tank, just finished acid bath and soaking and scrubbing. Anyway, there's a section of the sump for a refugium which is about 1/3 of the display tank surface area. What's better to put there? A...

Cheers! Yeah will definitely need to do more research. I've only researched clowns and chromis'S as they're going in first.

Ahh I see Yup Niger trigger. Ok so probably feed1/2 a cube a day when I have half that number of fish. 1) And then as I increase my stock feed a cube a day? 2) Also, does this mean I should get a 1/2 cube scrubber and change to a 1 cube later. Or start with a one cube? Will the latter be ok?

Hello, sizing my algae scrubber so working backwards here to work out feeding. So 105 gallon tank. Say I had 6-7 soft corals. Fish -2 clowns -1 fire fish -1 blenny -1 Bengali Cardinal -3 chromis -1 coral beauty -1 triggerfish - 4 or 5 snails Got a skimmer, 12x tank flow per hour, live rock and...

Oh yes, nothing like a good concentration gradient. And RO/DI water works wonders for that purpose. Thanks!

OH turns out dad has some HCL, excellent I'm soaking them in RODI water, no smell but it's only been 12 hours. Will update you guys about phosphate readings :)

Reckon a smaller dose like 10:1 followed by a one day soak is also ok? So I don't have to buy 80L of vinegar

Wow $500, out of my price range unfortunately. The Santa Monica hog for 1 cube feeding a day is $150 which is a bit better for my wallet :) Hmm I'll check some DIY builds

Ah ok gotcha. So that's why after vinegar soak they was in RODI and then soak in RODI for ages. Yeah mine is pukani. And yeah I have an RODI unit so may as well just use RODI water.

I read some reefers bleach their dry rock for 24hrs or soak in vinegar for 45mins, then wash it, then soak in water, add phosgard, then soak again in water. Then finally when clean, adds them to the tank. Then starts the cycle. Any thoughts on the usefulness of vinegar or bleach?

Won't tap water soak mean the rocks will absorb contaminants like phosphate? Ohh that's a shame. Oh well ill have to cure the rocks properly and then hope the nutrient export method helps keep the algae at bay.

Cheers Will be soaking in RODI not saltwater, to save a bucket of Red Sea salt hahaha.

Oh and...noise?? Air pumps aren't that noisy eh?

Cheers! I'll definitely do an RODI washout then and soak before I cycle then. Appreciate your advice :) In fact maybe I'll just cure the rocks fully and let everything fall off. Can cycle with a shrimp or live rock if need be after that. Thanks Imforbis I've learnt a lot from yourself and the...

Just researching at the moment. Considering chucking an ATS once my cycle finishes. Anyone used a commercial algae turf scrubber like Santa Monica's Hogs? I'd buy the $150 one for one cube feeding a day. It's the magnetic upflow algae scrubber. 1) Suggestions regarding this brand? I worry if I...

Hello! I am aqua scaping my dry rock for my new 400L marine tank. I've noticed a lot of dead matter on it and within the cracks like sponges and brown crust. I'm worried this will not only produce ammonia which I want for the cycle, but also foul my tank with phosphates and get me off to a bad...

Thanks for the suggestion :) yeah Amazon won't ship to my location due to import restrictions. Our country has crazy bio security. A lot of people in NZ use reactors and things but I feel like it's much more expensive. And combined with light feeding and stocking, I think macro or a scrubber...

Gotcha! Thanks for all your help much appreciated :) it makes sense to me also that the bacteria colonies would grow better if they had their nutrients there for them.

Ahh yes! And how about size? I hear people say you need a very large sump compared to display tank size to achieve nitrate and phosphate reduction?
