One of the ballast on my 20" T12 Coralife tubes died few days ago, so right now I'm running at 60 watts. I switched the sides the T12 and CFLs were on, hoping the one remaining low light T12 will get rid of the algae (more about it at the bottom). It's a 15 year bulb. So one side has bright 40watts CFL and other is the 20watts T12.
I was looking into replacing my bad T12 ballast. Went to Home Depot and found some 24" T5 fixtures at $15 for a single tube or $22 for the double tube fixture; 14watts or 17watts per tube. I ask them about replacement bulbs and they didn't have any. So I decided to wait and see what else I might consider.
What I'm really considering is the 48" T8. The double tube fixture is only ~$20-40 and the 32watts bulbs are 2 for $7. While 24" T8 tubes are $7 per tube at 17watts. I figure if I get the 48" I can replace all my lights, cheaper price too. The only problem I'm facing is that these are worklights and not meant to be in damp places ???, meaning metal enclosures. How is everybody dealing with this? DIY lights from hardware store. Metal enclosure and electricity near water.
I was also thinking of Vanity lights since they are meant to be use in damp locations, but the height of the unit is 1/2 inch taller than my cover for the aquarium. 3 mogul lighting for only $9 (will use CFLs), if I were to built my own, each mogul was $2-3. I might buy one and take it apart to see if I can get it to work.
My 100 gallon is doing very well.
Guppies: Too many to count
Khuli Loaches: 7
SAE: 1 (True in the sense)
Bamboo Shrimp: 2
Cherry Shrimp: #?
Lace Java Fern
No heater at 77 degrees fahrenheit.
Fish I'm looking to buy is the Hillstream Loach, cories (hoping for pygmy, but they're like $8 per, so something cheaper), small pleco (clown, bristlenose).
Guppies hang out all levels of the tank so it's quite hard to feed the bottom dwellers.
I replaced my Coral with 2 large pieces of Mopani driftwood. A LFS went out of business and everything was 50% off.
The Plants are doing very well, although low light and no CO2 mean slow growth (not filling in as fast as I would like), I can see my Pellia, Vals, Anarchais, Aponogeton, Sword grow. I don't know if my onion wll grow or not, it was one of those dried bulbs that came with Aponogeton bulbs. After 2 1/2 weeks my Lily bulb is still floating, so I think it's a dud.
At only 80 watts, I'm getting some algae that none of my Algae Eaters (SAE, shrimp, or Otos) are eating. It's white/grey fussy growing on my Java Moss and Pellia. It stays short.
