Miracle Gro Orangic Issues

Has anybody else ever had issues using this as a base substrate. Issues meaning harmful or deadly for fish/shrimp.

I currently have it in my 29G and 10G. Both are capped with another substrate and do not contain a lot of the miracle gro.

The 10G has recently turned into a cherry shrimp tank. I got some shrimp locally and within 2 weeks there were hundreds of babies in the tank. Now, a month or so later, I can count 3. There are also two ghost shrimp that have been in the tank since it was first set up. Is this an issue with the miracle gro or ghost shrimp?

The 10G is topped with regular sand, no traces of nitrate, nitrite or ammonia and was cycled before fish ever went in it originally.

In my 29G I use to have a bunch of bright red Cherries as well and over time they disappear.

Thoughts?

Exclamation MGOPS not really worth it!

I am using MGOPS capped with sand. I did a 6.5 week dry start method with crypts, HC, DHG, and a bunch of anubias. When I flooded the tank on Thursday I figured that the soil and mineralized and gone through it's processes. This is not the case, in fact I noticed the substrate bubbling right away. When I run my hand through the substrate it releases TONS of smelly gas bubbles. Hydrogen Sulfide! Aside from turning some roots black it doesn't seem to be hurting anything yet. But, I don't have any animals in the tank yet. Daily it shows zero Ammonia, Nitrite, etc... but the organic process is still decaying matter into HS. That could be your problem. As far as I know HS does not dissolve into the water column but it shrimp are near it when it releases it can kill.

I don't know a whole lot about H2S (is that right?) but maybe something I write will help you.

How deep is your substrate? H2S is produced by anaerobic bacteria. In order to remedy the situation, reduce the substrate to 1-1/2 to 2" and do a thorough vacuming if the substrate is gravel. Alternatively, you can poke around with a chopstick and release the gas, but you also have to solve the underlying problem.

How is your tank water circulation. Sound like you might want to increase it if possible. My HOB works better in the middle of the back side of the tank.

Plants - plant roots oxygenate the substrate. If need be, try putting in some more plants, maybe a small sword or other plants that have a large root structure.

Good luck!

I've had MGOS in 5 tanks for over 7 months with no issue. I haven't had it in a shrimp tank though - except for ghost shrimp. My plants in the soil tanks grow better than any other tanks in the house, I will probably never use anything but soil capped with black diamond blasting sand or SafeTsorb again, saves so much money and so much better than anything else we have tried.

I have one 10 gallon with only ghost shrimp in it, trying to get them to breed and it worked wonderfully but they need many, many dense hiding spots because ghost shrimp eat their young. Not saying they ate all your cherry shrimp but it is a possibility for sure that it is happening.

I have MGOPS capped with eco in my Mini-M and I have ~30 or so juvie RCS's right now. I didn't even really mineralize it; I just got some handfuls of it and sifted out twigs and rocks and stuff, then just threw it in the tank and then the eco on top of it. I did a DSM for ~2 months before flooding and saw no issues.

Yeah, I've increased the circulation. I may just have to drain it and siphon off a bit of substrate, then replant and flood. Thanks for the advice. I've kinda left it alone for 24 hrs so the detritus will settle and I can actually see what is going on, but I think maybe draining it, lessening the substrate and replant may be the best way.

I have no problems with it in my 10 gallon betta / shrimp tank. I do make sure to use a thick layer of sand to keep any nutrients from leaching into my water.
