So, yesterday I did another 50 gallon water change, and finished off the gravel siphoning, which was only about 15% of the remaining gravel. There's still some algae/cyano
growing on the overflows and on the LR
, and I can still see some gunk in the overflow (below the lower intakes) and I don't really know how I'm going to get that out of there, maybe I'll try to find a longer tube cleaner.
The next step is to replace all the pump hoses and clamps, pull the U-tubes and clean them out, clean the powerhead, and give the sump a good once over again (rinse bio-balls, etc). I also might rotate the bioball tower and install a filter sock on one of the intakes, the sump still gets quite a bit of chunky waste in it.
Anyways, here's how it looks now:
Full tank shot
Also you'll notice the Koralia 4 powerhead. I just got one because I wasn't sure he wanted to pop for it, even though he needs 2 and it sounded like he understood. He also has the protein skimmer ordered so that should be in by the end of the week.
We also discussed replacing the substrate, since the gravel siphoning just couldn't get all the gunk caught in it. The waste is heavy enough that it won't get sucked up, Python hoses have that shutoff that really slows down the flow rate, no matter what level the other end of the hose is at. So we're going to replace it in sections. The next question is with what?
Obviously there are 3 choices: aragonite sand, aragonite, and crushed coral. I'm thinking that a mix of aragonite (Arag-Alive brand Special Grade Sand) and Florida Crushed Coral would look nice. Or even just the crushed coral. Either way, the pH of the tank won't budge from 7.8, which is why I think mixing the 2 would be good, best of both worlds. Any opinions?
