Should I reseal 300 g 8’ glass cages tank? It does not leak, although has flat nonsticky silicone on one corner and a chip in another corner. If so what type of silicone is ideal and can it just go over old silicone as long as it still touches glass? What about placing new pieces of glass on...

I know I've made mention a time or two recently that I was interested in setting up a dream reef, the kind of reef that I've wanted ever since the early 2000's but I've never been able to do for one reason or another. Something in the neighborhood of 300 gallons that I can have for 20 years and...

I have a 90 gallon FOWLR moving up to a 300 gallon mixed reef. It’s a very costly endeavor. I still need to decide on lighting and sump. But my Eshopes S200 is giving me fits here lately I can’t seem to get it adjusted properly, and keep it there. Every 3 or so days it just pukes and puts all of...

My 300 gallon / 1.100 liter drop-off display tank was in the living room, and now we remodeled the house and ended in the hall. Allowing a complete restart. Despite losing the peninsula feel, where the tank was initially build for, I do think the new place is ok, And now 4 months running and...

The tank is 96” by 30” by 24”, 300 gallons. Will they have enough room to establish separate territories?

Hello my fellow reefers! I am not a novice, but have not had a tank in about 5 years due to a move back then where I had to sell off everything. We have rented since, but just closed on a house at the beginning of this month (May) and it is way past time for me to get back into the hobby that I...
