So, after 4 months, I can no longer deal with the sand. It was nice to look at but came up with the following ANNOYING issues:
1. The Oscars started "shoveling" the sand all over the place causing the sand to always be floating around and getting all over the deocrations.
2. The sand (white) started to turn a dark grey/black in sections. That probably had something to do with the poop and left over food.
3. Everytime we cleaned the tank and refilled it with water, it would get sand all over everything. I like a "neat" looking tank - within reason of course. I'm not stupid, I know the O's rearrange things.
4. The white sand was a great back drop for the dark colored poop that comes out of these fish!! It was almost instantly dirty looking again.
5. The pleco liked to create craters in the sand and would sit there and flip the sand all over the place making a huge hole to the bottom of the tank.
6. Sump filter - it was constantly clogging the filter material. 3-4 times a week we had to rinse them. See reasons #1, #2 and #5 - especially #1 and #5 for the cause of this!!
So, all the sand came out except for a very small amount under the gravel - not even a full layer. Now there is gravel in there again. My levels are still lovely and the tank is clear again! I went with a mix of colors - black, blue and white. The poop is hidden nicely and it makes for a pretty tank.
The tank now.... The Pleco is still alive - hanging between the heater and the sump box. You can judge how big he is compared to the Oscars.
Piglet - age 5 months - about 8.5" long (loves the camera!!)
Red - age 5 months - about 8.25" long (too busy begging for food to hold still for the camera!!)
Red and Piglet - yep those are fight marks on the side of Red !
Hope you all are doing well!
