If u change the substrate will the poly get stress??? Im planing to change mine to black.
I don't think it stresses polys out. I took out my sand/red gravel mix yesterday with a plastic dust pan. It's a 6 foot x 2 foot tank.
- Started on the left side first then shifted all my decos to the right(driftwood and large anubias) . If there is decoration on the opposite side. They take refuge there and seem very calm.
- Then moved the decoration to the opposite side. All fishes moved there. After the large portion of sand/gravel was taken out. Water clarity was cloudy white.
- Took off the cylinder chamber and green connector fittings because inlet diameter is smaller. Gravel will create a blockage during siphoning. Started the W/C process with the tube only from python hose. It works great to vacuum loose gravel and sand for my 50% water change.
- Filled tank with fresh water.
- Waited 4 hours for fish to acclimate a bit from stress.
- Rinsed the previously used substrate and poured about two 5 gallon buckets full into the tank around 7 p.m Sunday night. Just poured it directly in from the top. Didn't do anything fancy.
- Water become pretty clear by the next morning and no issues.
