CaribSea Tahitian Moon Sand black vs. flourite black sand

Or what about mixing flourite black and flourite sand...

I have flourite black sand and its pretty black. For what its worth I also have pool filter sand in another tank and in my opinion I like the pool filter sand tank better, strictly on a color basis, it seems more natural.

Alright, it'd certainly be cheaper. I like the way black pops against the colors of fish, though. Does your PFS get algae on it bad?

Coal slag sand blasting grit (Black Diamond/Black Magic). $5-$10 for a 50 lb bag. Makes a great black cap or main substrate for wwaaaayyyy cheaper

I have it as a cap over MTS and it is black...and looks good.

I have the Tahitian moon black sand in my 29, its all black and looks good. I havent tried the the fluorite.

link didn't show up....

the black moon sand seems really small. Should I worry about this compacting over time? Or will is stay loose as long as I do regular movement of the sand?

Umm yeah the lower layers may compact a bit if you have a ~3"+ thick substrate but it doesn't seem to be bad or anything, i have about 2.5" and all my plants/roots are doing fine, I poke around once a month or so. The top inch or 2 has always been pretty loose and not compacted at all, it's just the very bottom of it.

Okay thanks, due to my budget being a lower one. I think I'll go with PFS as a cap for now. Because quite honestly, spending 100$ on sand, just doesn't seem sensible.

HolyAngel, are you using the sand exclusively? If so, are you using root tabs or something similar for fertilization?

Doesn't say anything about root tabs in her journal...If it's a low-tech tank, they aren't as essential..


EDIT**** Just read, she recently upgraded her lighting to a odyssea t5ho.. She's going to need some root tabs

Been using root tabs since I started the tank as well as the flourish line of ferts

And yes I've been using the Tahitian moon sand exclusively in my 29 ^^

I'm a guy btw

i use black diamond in three of my tanks and i like it little harder to clean the gunk off the top because it is so light but its cheap enough if you do need to add more later on if you siphon to much out of the tank i also use 3-4 inches of it in my tanks so far in almost a year i have no problems with it compacting but i also have a few different loaches that love to burrow in the sand my horsehead loach loves to burrow the most

What fish are you getting? Tahitian moon and coalslag are not so good for cories/softbelly fish, where as flourite sand is. I've found the flourite is a little gray but still looks good. You could also check out estes black sand, I've heard a few good reviews on it.

I have 8 cory's and 4 kuhli loaches, they love the Tahitian moon sand and their bellies/barbels don't get red or damaged at all, I've never seen it happen since I've had it and I've had the corys the longest.

Coalslag I've heard can be sharp tho and can cause damage, the Tahitian moon does not have any sharp particles in it.

My apologies. Wish they had a gender is ..... thing on here. Sometimes it is hard to tell by user names.

Thanks for the heads up.

Due to recent cuts and moved priorities for this tank, I can't afford to spend 100$ on just sand. (It will be going to a better light (catalina) and another filter (catalina CA1000) So instead I will be using PFS (pool filter sand). The sand I located is a nice color and is consistently smooth/grain size. Maybe later down the road I'll consider moving this tank over to either flourite sand or black moon sand.

Understandable!
