Low Tech 90 Gallon w/ DIY Sump
Just purchased a used 90 gallon off of Craigslist locally. Figure i got a pretty good deal on tank/stand/canopy with a brand new 48" T5no fixture for 180 bucks. In the coming weeks im looking to build a sump trickle filter / refugium but initially I have some questions / concerns regarding the tank and stand.
Stand is a fairly inexpensive pine set up that to me does not look to be the most sturdy. Does this look pretty standard for a tank of this size? I was thinking it may be best to try and do some reinforcing prior to setting up and adding water to the tank.
Should I be concerned?
Second, the tank has what the previous owner called grazing? on the inside of the glass, said that the guy that he had purchased it from pretty much never cleaned it and it ate into the surface. When its we its pretty hard to see but empty its pretty obvious in the pictures. Anything that can be done to repair? Ive tried vinegar and a razor blade thinking maybe it was just calcium build up but that didn't have any effect.
Came with a brand new Deep Blue 2 bulb 48" T5 normal output. Is this going to be enough light for a 24" deep tank to be a low light non CO2 setup for decent plant growth. Figured I would replace the 10k and actinic with 6500k or maybe one 6500 and a plant bulb.
