  • Plants picked by tank size and by current stock availability.
  • 10% off your first build, materials and fees.

Sized for the animals

An installed SLESS tank runs on its own when the tank fits the animals in it. Tell me which animals you keep or want and where the tank will go, and I choose the size and layout. If you have a fixed spot, tank size or equipment to keep, tell me that too and I will say what fits.

Already have a tank with animals in it?

New tank, current tank still running: I move your current tank to a temporary spot, keep it running and move your animals over once the new tank tests safe. Rebuilding your current tank into a SLESS tank: I tear it down and hold your animals in a temporary container while I rebuild it in the same glass. Either one adds an existing tank fee to the installation fee, by the size of your current tank.

"How NOT to Kill" guides

Species guides I am writing: origin, behavior, what kills them in home tanks, and breeding. Vote for the ones you want first; the votes go out with your request and set the order I write them in.

Three steps

How pre-orders work

  1. Add what you want

    Kits, installs, merch, reservations and votes all go into one request list. It stays in this browser while you look around.

  2. Send the list

    Your name, email and zip. A local install adds a few questions about your animals, the spot and the stand.

  3. I reply by email

    With the final price, shipping and timing. You pay only if you agree.

To change a request, reply to my email or send a new one.
