    HELP! Low KH and Ca

    I have issues with TM in the past, specifically low alk. I switched back. Reef Crystals is good but hafta say testing is key. LaMotte for alk and Elos for Calcium/magnesium are the best imo. Just don't panic or move too fast as previous posts have said.

    Ocean Acidification and Corals

    A recent World Resources Institute report estimates that nearly 60 percent of the world's reefs are threatened by increasing human activity. The expanding human population and its activities may impact coral reef health in a number of ways. Development, urbanization, and agriculture lead to...

    Ocean Acidification and Corals

    Watched it last nite. When they talked about the amount of carbon absorbed by the ocean that was scary no doubt. Coral is migrating due to temp's rising (in Japan and elsewhere) but unless we check carbon output that won't matter.

    Par 38 red Led for refugium

    I also run the white PAR 38 bulb. 3000K and it is doing the job so far. Anthelia and a brown monti cap are growing like mad under it as well. In fact the monti developed some dark green and turned darker under that bulb.

    Small heaters?

    a lotta reefers, including me, run 2 heaters instead of one. In my old 125 I had 2 100 watt instead of a 250 watt. Prevents a bad heater from frying or totally freezing your tank and are smaller/easier to hide.

    Great Barrier Reef Has Lost Half of Its Coral in the Last 27 Years

    Just covered this report on PBS News Hour and channel 2 news. The woman from the Smithsonian talked about how poor water quality/high nutrients from runoff feeds the crown of thorn starfish which I never heard before. Thanks for posting this.

    Recharging GFO, has anyone tried it?

    right. i test the ph of ro/di before and after it rinses the gfo

    Recharging GFO, has anyone tried it?

    After I recharge I test the ph of the last rinse water. If it matches then you're all good, no residual lye. I don't do the acid wash. Even if a little lye is left over it'll just raise your ph and calcium level, lol

    Setting up natural filter complex and food source for my system

    man, amazing set up. ATS, cryptic zone is ideal and clearly you have the room and volume to do it. I think salt depends on livestock. In my lps/softie dominant tank I use IO and supplement alk and kalkwasser. IO would work in any tank, imo, especially if you run a calcium reactor.

    Need to pass on a sea hare that no longer has alge to eat

    I plan on picking it up tomorrow. I'd be glad to pass him around once he deals with my algae.

    Should I worry about my pH?

    Saturated kalkwasser is what's always worked for me. I mix 1-2 tsp of kalk per gallon of topoff water and dose at nite. Keeps my ph from swinging dramatically and boosts my skimmer. I really notice it when I get lazy.
