Long overdue update.
Fish
I'm proud to say all my fish are healthy and doing well. I been wanting to add more, especially to my 30 cube, but not until I get the GHA under control. Additional bioload will not help in any stretch.
Coral
My coral is doing fair for the most part. Some are encrusting and growing better than others but none have been lost in the longest time. I'm testing zero nitrates but I'm still having troubles believing that. It is possible though, if my nitrates are zero than it means my phosphates are high. Either way, I'm trying my best to get them down and hopefully my coral will color up more and grow faster.
GHA/Nitrates/Phosphates
Slowly the GHA has been growing in my tank. It's not completely out of control but getting near that level. I'm running RO/DI but I haven't checked the TDS for some time. Likely I need to replace the DI and actually probably time to change my RO membrane. If I test the RO water only, what should that level be before it hits the DI? The RO membrane is 2+ years old!
I still need to buy some different flake foods. Orr2003 posted a link of low phosphate dry foods, I need to get some of those. I did cut way back on the frozen immediately though. Right now I'm feeding IO Marine Chips most days with only the occasional frozen food day.
I think about 75% of my problems are husbandry issues. I have been told even before I started that proper husbandry cannot be overlooked and I did it anyhow. I'm not totally lazy on it but I have let some things go too long. One problem is blowing off my rock. A couple months ago I did this and was embarrassed how polluted the water column became. I have decent flow in the tank and thought that would go a long way in keeping detritus from settling in my rock but apparently not enough. It was horrible. Plus, with the GHA I have growing it was flying everywhere after getting dislodge by using the MJ1200. I was taking a fish net catching a lot. I have done this several times since and it gets considerably better each time. Now the flow on my 30cube is a different story. I don't have enough flow it in and not surprisingly it has the biggest GHA issue. Time for another powerhead me thinks.
While I doing monthly water changes a lot of detritus is settling in my sump during the month. I have started to siphon this out between changes. I need to do it at the very least weekly.
Also, while I'm so dreading it I think I need to remove my HDPE bottom. Way back in this thread I posted concerns about the detritus getting trapped underneath. Well, over time some more has gotten trapped. While it isn't a huge amount I do think it is probably enough to be contributing to my problems. So in the coming weeks I will need to remove all my rock, remove the HDPE, and hopefully get my rock back in a similar fashion to what I have currently. I love the aquascaping and hope to keep it similar after rebuild.
Chemistry
In another thread some time ago I posted issues with my Calcium being too high. I first noticed it when the sandbed of my 30 cube was setting up like concrete! This was probably back 5 months ago and I took my Kalk Reactor and Osmolator offline at that time. Since then, I have been topping my tank off by hand. My ATO is ran through the Reactor and the line from the Reactor to the tank is not long enough to stretch to the pump directly so I need to run another line. Anyhow, after taking the Kalk reactor offline my CA has slowly dropped from 520 down to 450. I suppose the CA from my water changes is enough to keep it at that level alone... My ALk on the other hand drops all the time. I started dosing Baking Soda with anywhere from 2-4 tablespoons a week (not all at once). This is maintaining my ALK in the 7.5 - 8.5 range but I'm wanting to get it up to 10 and keep it steady there.
My pH and Magnesium are all testing great. Since I don't have a phosphate test I have no idea what it is but I have a suspicion that it has been really high but hopefully dropping from some of the changes I have made.
