I changed out the gravel substrate for a sand/flourite blend in my tiny little 6 gal. I put all the existing gravel into a nylon net and left it in the tank. I'm not sure how long I need to leave the "gravel in the nylon" in the tank.
Before this change my water parameters were:
Ph 7.4, Nitrite 0, Amm 0, Nitrate 5.0
After a partial water change and 24 hours later I've got:
Ph 8.0, Nitrate 0, Amm 0, Nitrate 5.0
Not sure why the Ph swing as I performed the water change in the same way that I always do. Maybe it's due to the new substrate?
Anyway, I want to use this little tank as a rooting tank for the clippings from the plants that I take from my larger tank. The 5" pleco that is currently in this tank is going to a much larger tank. I'll need to stock the tank with something else to keep the cycle going. I wanted a betta but the current from the filter is way too much for a betta and no way to adjust.
Due to all the plants I'll need some good algae clean up on a consistent basis. Could I do a few otos or SAEs??
Any other ideas??
