Been wanting to start a journal on my 90gallon planted tank for a while, but now seemed like a good time.
Been keeping aquariums since the late 80ís, and have had a planted tank since the mid 90ís. My main interest in aquariums over the years is split between Lake Tanganyikan cichlids, and planted tanks. Currently running 6 tanks in the house, ranging from 6 to 180 gallons. My main planted tank is the 90.
Recently, my wife and I were talking about repainting the dining room which is where the 90 resides. At the time, it was a 75 gallon tank, and my thought was that it would be a good time to go bigger. The tank had to be taken down completely anyway, and weíve always thought having some additional height would be good for the plants. Thanks to an assist to Kendall-Jackson, she agreed. At same time, Iíd admired the look of several other tanks here that use BDBS as a substrate, so why not change that out too?
So the weekend before Thanksgiving I picked up a new 90 gallon tank with black trim and silicone. Painted the back with black paint, and got everything together for the move. 100lbs of BDBS rinsed and in buckets, extra buckets and towels etc. Room painted and tank move went smoothly. This is what it looked like on that Monday night.
Here it is almost 2 weeks after set up
<image coming soon>
Tank 90 gallon, 48Ē wide, 24Ē tall, and 18Ē front to back.
Filtration: 2 Eheim 2028 canisters, return spraybar on far left, other return a jet on far left, both intakes low at far left

2 Anubius (sp)
The 75 became overrun with crypt spiralis, so as part of the move, most of it was removed. Since the tank swap, Iíve seen a significant amount of melt from the cryptocoryne wentii and some from the spiralis. Most of the other plants are showing new growth.
My goals for this journal are to get feedback, improve the health and growth of the tank, improve my maintenance routines, develop a better aquascape, and dive deeper into fertilization and lighting to further those goals. Bonus may be better identification of some of the plants I donít have correctly named.
One thing that has to improve is the BBA situation. The 75 had been set up in one form or another for 19 years. It had two major shifts in that time, going from a 75 down to a 29 for a few years, then back to a 75. The substrate was last altered/changed in 2008 when the tank was changed back to the 75. From reading other journals and posts, one thing that may have contributed to BBA was the substrate. It had not been deep cleaned or vacuumed in years, so there may have been a lot of dissolved organics held there. Iím hoping that the swap to sand will eliminate that as a source.

Water Parameters measured this morning, prior to lights and CO2 coming on and before a water change. I let the tank go 2 weeks without a change as it was setting up. Will be doing a water change shortly, and will update these values this evening, post change and after CO2 has been running.
gH 8 degrees or 142ppm
kH 6 degrees or 106 ppm
The tap had the following values:
gH 4 degrees or 71ppm
kH 4 degrees or 71ppm
Seemed odd to me that the tank had higher hardness levels, but that may be due to fertilizer additions, will have to research this some more.
Couple of shots of some plants i recently received.
Noticed the pictures are upside down and repeated at end of post how do I fix that?
