Hi, I'm looking into culturing my own Phytoplankton and was wondering if there are any guidelines with respect to how much to feed. I realize that the density of the culture may vary, but IN GENERAL - how much and how often would one feed the main tank, or at least what amount would be a good...

Yes, I'm aware of that. What do you think about the following possibilities: Bristle worms, amphipods, copepods, and microhermits Trochus snails (Trochus intextus) and strombus snails (Strombus maculatus) macroalgaes including red macroalgae (Gracilaria parvispora), green macroalgae (Ulva...

Hi, I've just set up a new much larger (110) gallon refugium and was wondering what type of critters would help with the nutrient export process. I know I can have some seahorses and things like that, but I'm mainly concerned with adding animals to help with nitrite/nitrate control. I already...

How can I figure out what the flow rate of an overflow would be for 1", 1.5", 2" pipe? I am trying to figure out what size pump I need to feed my refugium which has a 1" overflow which will gravity feed the sump. Thanks.

Thanks. That's a great idea with the live rock. I think I'll also do a water change on the main tank and use that water for the new one.

Hi, Thanks for the quick reply. I quess the simply question should have been "Would it be safe to put all this stuff into tank with new RO/DI water which is salinated but has never had any livestock in it so it has never cycled. I would like to put everything in there first to isolate it before...

Hi, I'm purchasing the remaining livestock from my LFS which is getting out of saltwater. It is mostly corals, an anemone, maybe a few snails and shrimp, and lots of chaeto. I can put all the critters into my display tank, but I want to put all the chaeto and some rocks which have lots of...

Thanks Thanks Thanks. I was pretty sure that would work but I've also made some very bad "educated" assumptions before.

Hi, I have a tank (a sump actually) which cannot be drilled. It is gravity fed from the main tank has an outlet at about 3", which is going to gravity feed a new refugium I am building. My question is - Can I plumb and elbow to the current outlet in order to raise the water level from 3" to 6"...

Crazy Mangroves Crazy Mangroves You are correct. I suppose I should have qualified that with "growing like crazy compared to other mangroves I have seen or had myself". I have them attached to styrofoam and they are submerged from about the bulb down. The roots are very dense and bushy and...

Pics? Pics? Not at this time. They are in the under display refugium and at the back. You wouldn't tell much by the pic, and I really don't want to disturb them just yet. Maybe when I figure out what to do and take them out for trimming I'll post some before/after pics. Thanks

Hi, Can a Mangrove be trimmed at all? The leaves aren't so bad but I might need to give them a trim as they get too dense and bushy. The roots, on the other hand, have grown into a huge mass and will soon choke up the chamber in my refugium in which they live like a house plant becomes pot...

Yes to Mangroves Yes to Mangroves I have a few in my fuge and they grow like crazy, along with the chaeto, so obviously they are feeding on some nutrients which one has to assume would eventually show up as nitrates if not removed somehow. My entire system relies soley on the fuge (as above...

Hmmm...... Hmmm...... I use a bunch of mangroves in my refugium and they grow like crazy. Huge root systems too. It is my understanding that they do an excellent job of exporting nutrients. This makes sense since they are definitely feeding on something to be growing so vigorously. Also...

What do you use to test pH?
