So anyway,

This is a 75 gallon tank

Here are some pics of problems. I was using a razer blade several months back and got a little too close. Then algae started growing in the gaps. I have had not problems with the seal. Should I cut off the little areas and put some new silicon over or should I completely redo the whole seam?

Thanks for the advice!

THe main issue is that new silicon doesn't stick to old silicon very well.

It appears that this tank is set up and running?

I'd cut off the extra that isn't adhered to the glass, keep an eye on it. If it's peeling back, you'll have to reseal the tank.

I use a credit card to scrape the algae off the glass in my tank and it doesn't damage the silicone. Be sure to get a new-ish one ( go the somewhere like gamestop and they'll usually give you a new card for free) and cut off the end with the scratch off stuff. I've used it in my tanks for about 5 years now and I usually go over the silicon by accident but my silicon looks brand new.

Anyone else have any recommendations?
