    PVC Glue in aquarium

    While the piping above our aquarium was being installed, a drop of PVC glue fell into the empty tank. This wasn't noticed until later, well after the glue had dried. Will this cause problems? What is the best way to clean if so?

    Need Water Change Advice

    Hey everyone, I have a 125gal DT and probably a 10-15 gal sump. I plan on doing a 10 gal water change from the DT but I have a feeling that its too little. It is currently a FOWLR system with 2 snails, 3 shrimps, and 12 fish. Would it be bad if I did 10 gal changes every 2-3 days to get...

    Impacts of cooking on the aquarium

    The other day, as I arrived home from work, I opened the door to a smell of slightly burned stir fry. It's not uncommon for me, my wife, or the baby sitter to have cooked up something in the kitchen and created an odor which permeates the immidate living space surrounding the kitchen. As the...

    Green Spaghetti Finger Leather Help!!!

    I have had this spaghetti leather for about two months now and it has been doing great until the last week. It has retracted all of its polyps and shrunk to 1/3 its normal size. I have checked the water parameters and everything is on par. All the other corals in the tank have had no changes...

    Should I always leave my lights on with corals?

    So I am new to corals and only have one at the moment, a zoanthid. I am only using the stock LED lights that came with my aquarium kit so I was not going to introduce any corals until upgrading my lighting system at all, but it seems I gave in to try out one that was known for not needing much...

    The people at the lfs screwed me and my clowns :(

    I can't express the anger I am in right now....the people at my lfs basically told me to leave my tank for 3 weeks before adding fish with live rock. They told me absolutely nothing about the Nitrogen Cycle. After reading more and more on these forums I have learned about the Nitrogen Cycle and...

    3 miscellaneous questions about reef aquaria

    Water Chemistry Question: When water evaporates our tank, salt remains, that's why the higher concentration of salt and less water, hence the SG rise. Does this happen with Ca, Alk & Mg when water evaporates? Do these elements stay in the water? Normally we pour some water in to bring the SG...
