Lotus Vor-Tec Replacement Filter Foam Sets
Replacement coarse, medium and fine mechanical media for an older box-filter installation
Choose the variation that exactly matches the Lotus Vor-Tec 12000, 16000, 20000 or 30000 filter named on the label. The set restores the staged mechanical layers that trap larger debris first and progressively finer suspended material afterwards. Keeping that order reduces rapid clogging of the fine sheet and preserves more even flow through the filter.
These are current Oasis-listed replacement sets for legacy Vor-Tec filters; exact layout is model-specific. Older filters may have changed internally during production, so compare the existing foam dimensions, number of layers and any holes or slots before cutting or discarding the old set. Where the sheets are supplied unpunched, use the original foam as a template and cut cleanly so water cannot bypass around ragged gaps.

When foam really needs replacing
- It remains permanently compressed after cleaning.
- The sheet tears, crumbles or no longer holds its shape.
- Water channels around enlarged holes or damaged edges.
- The original grades have been mixed up or are missing.
Routine dirt alone is not a reason to throw mature foam away. Clean a portion at a time and maintain good oxygenated flow. If a newly cleaned filter blocks almost immediately, investigate pump size, algae, fish load and upstream solids rather than simply fitting finer foam.

Frequently asked questions
Should I cut holes before fitting?
Only where the original arrangement requires them. Use the old sheet or filter grid as an accurate template.
Which grade goes first?
Water normally meets the coarse layer first, followed by medium and fine. Follow the filter manual if its layout differs.
Can I wash foam under a tap?
For routine biological maintenance, rinse it in removed pond water. Chlorinated tap water can harm established bacteria.
Can I replace just one damaged sheet?
Yes if the other grades remain resilient and correctly shaped, although a matched set is often more convenient on an older filter.
