Thanks to Community Member Phantom240 for posting this deal.

Good Deal?

Amazon has a limited time deal on Flourite Black Sand. Unusual to see it marked down. A few bucks cheaper than even LiveAquaria

Something seriously wrong with youMad
I'm just happy to see aquatic items here on SD. More more more, Thumbs up if you agree !!
Dealing with the same issue, I had 6 "marimo balls" in there and each month I pulled out about a quart sized ball.
I'm convinced they're selling fake marimos online that's why they create tons of hair algae in your tank. I kept them for so long because my corydoras and shrimp love them. But I have recently gotten rid of all of them now.

actually it would get kicked up and buried, decompose and release noxious gases every time it gets disturbed. it also makes the water cloudy every time it gets disturbed and RES will do this often. RES are best with larger rocks they can't move or eat with a clean bottom allowing the filtration to do its best job and keeping the water clean.
Fair enough, I'm not a turtle guy honestly.

Quote from DangerQuail :
I personally like their fluorite black substrate way better. Sand is such a pain in the butt substrate to use. Plants can easily root in fluorite black and sand can get compacted easily.

Additionally the chips in the non sand substrate allow for oxygen and gasses to be exchanged which prevents anaerobic decomp from occurring in your substrate that could bring diatoms or worse, dead fish.

Any aquarium product you buy should be tailored to your lifestyle and the design of the tank.

I hate gravel vacuuming and any care in general so I buy the larger fluorite substrate, have tons(thousands) of Malaysian trumpet snails, and a heavily planted tank.
I'm also running tons of air into the tank and the water is circulated completely every minute or so via chemical and biological filtration. I do not use any mechanical filtration outside of prefilters and sponge filters which are more biological than mechanical imo. Gotta keep the snails from killing my canister filter.

I do water changes once a month and clean the filter every 90 days. Other than that they only get food. If one of the fish die the snails will remove it in under a day anyway.

Thanks for the info. Do you have a link to the fluorite substrate mentioned?

Great stuff. I researched substrate for hours, before deciding on the Flourite Clay. However, I had to rinse 3 bags of it for about 3-4 hours before it was no longer too cloudy.

3 bags worked almost perfectly for a 29 gallon.

The color also looks very natural. It is not jet black, more like a lighter black BUT it looks real/natural.

It is heavy enough to not get sucked up with a syphon if I am hovering around the sand sucking up debris.

Yes but the sand can prevent food particles and waste from falling deep into the gravel cracks and crevices where scavenger fishes can't eat it. I also have a heavily planted tank so maybe different than non planted. I always mix two parts gravel with one part sand. But vacuuming sand is a big problem. But it's been a year and a half and I have never had to vacuum nor do I ever intend to. I have one canister filter on each tank with the add on spray bar. I light little swish on the gravel surface a few times 30 minutes before cleaning the filters usually gets rid of any excess waste. I rarely do this though.

Read the reviews before ordering. this sand substrate takes a long while to clean. Not everyone is willing to spend an hour cleaning substrate. If you like black substrate, another good option is to try eco complete, it's more of a rocky gravel, made of volcanic rock, that doesn't need any rinsing.
I like Eco Complete and even though it says not to rinse because it has good bacteria in it I will never make that mistake again! I had milky water for over a week. And Just like the Flourite different batches can vary. I have gotten batches of both types before that needed almost no rinsing and others that where like milk.

That's what I said in an earlier post. Spending an hour or two to properly wash aquarium gravel is the LEAST of my worries when setting up a tank. Tank maintenance is in the hundreds if not thousands of hours depending on how many tanks and the scale.
At least the people I know aren't happy with just ONE tank, they have like 10 on racks in their garage and then one or more inside. Some have dedicated rooms in their house just for fish tanks 😂

So it falls on deaf ears when people complain about such a trivial task. Just wait until they're doing something that really sucks like manually scraping algae off plants, Or manual removal of snails,Isolating and treating sick fish.
Keeping fish is tedious work. 🤷 ♂️

I assure you no food every makes it to the cracks and crevices of my tank. 🤣 If you haven't read about them before- Malaysian trumpet snails. They are ravenous scavengers that burrow through your gravel. For every one you see there are 20 you can't see in your tank.
Makes tank maintenance effortless because they are the second rung from the bottom of the food chain that most tanks lack.

I will have to get some. I am in Florida and we have something similar. They are always under the gravel and I know just the spot to get some. Who knows they may Malaysian Trumpets as I read they have been an invasive species to Florida since the late 60's. I catch all my snails at night as there are multiple species out in the thousands in the canals at night. I think my Zebra Loach may be killing them but I usually will throw and handful in every couple of months so he can't eat them all. I will grab a few tonight they should breed quickly in my 20gal then I will move them to the other tanks when I have a bunch.

That's a trick because hillstream loaches can't be caught in a planted tank. It's more impossible than catching ottos. You have to take all the plants and fixtures out. Catch every other fish then you can focus on the zig zagging impossible to catch fish.

Sometimes you may get lucky and be able to take them out while they're attached to something. Ottos like hiding inside the space between amazon sword leaves so if you remove the whole sword mission accomplished.
