I would really work hard to try and get that Mg up......most algaes dont appreciate Mg levels at or above the accepted range.......If one of your "big three" (Ca, Mg and DKH) is out of whack, it can have a big effect one everything:wink:.....

Again, I will voice my thoughts... Flow, Flow and more Flow!!! I personally think that is your problem. You have some dead areas in your tank, most likely within your rockwork, these areas are trapping the poop and stuff and thus creating issues... The goal of flow is getting it everywhere. I speak from experience!!!! Remember I had HA and Cyano, and once I got the flow throw the rockwork, VOILA!!! it went away. So just my 2 cents there. We already discussed on the phone, what I think you should try. Have you? Why not?

Sure I have Mg. I dose it -but I guess just not enough. I've doubled-up my doses and we'll see how that goes. As for Strontium, I'm a bit torn on that one. I've read in several places that you get plenty from regular water changes and there's no need to does it at all. That said, there doesn't seem to be much danger to over dosing it either so I put 1/2 tsp of Sr in every other 5 ga water change.

On the flow topic, I tore the tank apart the other day and still couldn't find the damned sea hare remains. took me hours of plucking HA from rocks but I did manage to open up the rockwork a bit so we'll see how that goes.

Skimmer is still acting up an overflowing periodically -not that there's much to skim with all the water changes I'm doing. I'll do another tonight.

I don't know if you are aware of this calculator, but this will tell you how much to add of whatever it is you use to bring up your magnesium level.

Yup, I've seen several calculators. I just don't like massive changes in any tank parameter in a hurry.

Also, I'm trying to find a 'recipie' that works for my setup so that I can dose specific amounts of Ca Mg Alk with my water change each week. If I can find the 'magic' numbers then I should be able to maintain fairly stable levels with my weekly water changes and not have to do any other dosing.

Thats the idea at least.

Use that calculator and dose to get to the proper MG... If you need to spread the major dose over 2 -3 days, then do so....

Once you are at the proper level, then as you stated, spend time trying to find out that daily recipe. And if you need to do a bigger dose again, then do so... Eventually you will get what the daily amounts will be

turn off UV if you are using pellets. UV will take away the effectiveness of the pellets
