I am looking at a total loss...Learn from my mistake

[kaboom]

100% loss is very painful, the worst I've experience is 50% and it hurts. Tank and plumbing design is utmost important to avoid such disaster. On my most recent tank I eliminated the sump and made a larger over flow to accommodate all gears, it's the best design change I've done in over 20 years of reefing. Without the extra plumbing, reduced noise and lower maintenance, it's given a me a huge piece of mind. The only thing that could possibly go wrong now is my Tunze osmolator but in my 15 yr experience with the product it's rock solid.
Consider sump-less system my friends.
