150gal FW to SW conversion

I don't even want to try to explain the chemistry behind all of this. I'm sure he is soaking in saltwater, so he will know what the test results are, given the difference in acidity and balances of FW compared to SW. Check out this pdf and all the crazy complexity that is concrete.

I see what you mean. When I think on concrete, I think of something solid. But the cement portion of concrete is made primarily from limestone. So it makes sence that it would be alkaline. Still curious how this translates into the water column (is a portion disolving, are gases released, is it a chemical reaction with the salt water - or a mix of all three). So, once it has stabilized, its safe to add to the display? Do you add bacteria cultures while it cures too?

Sorry to have sidetracked the thread. :( I'm home with pnemonia - nothing to do. LOL

The goby has made himself a home and completely covered some rock about 6"-8" high ..this could present a ptoblem later when I add soft corals .. maybe the goby was a bad idea lol.

hey Mike i would just soak it in plain old ro water until ph statrs balancing out....no need to waste salt water for now...then once it starts dropping then cure for additional week or so in salt..or if you have access to a creek or something dump it in there for month or so....Let me know if you want i can grab a bag of quikwall and bring it sunday for you. its like 15 bucks for a bag should do quite a bit of rock...make sure you guys are using the pure crushed oyster shell(no additives) check the bag make sure no oils or anything added.

also you can add some biospira or like product that will help seed it towards the end of ph cure

Here's my algae scrubber after first cleaning 7 days after install. Its gravity fed running 4 26w cfl. First cleaning was just brown algae and smelled just like siting near the beach. Much better than skimate lol

 

[Dowtish]

The scrubber is awesome. and I am officially hiring you to be a consultant on my overflow.

thx guys anytime any1 needs any help with DIY junk LMK :)

 

[gmoney243]

also if any1 has any questions about algae scrubbers .. algaescrubber net has a great faq section with lots of questions and answers .. also rumor is they also cool your water very good and especially if u point a fan at them u can replace a chiller ... although i dunno bout that since i dont run Halides and theres no real heat coming from my system.
