Well, actually after all was said and done I purchased 4 twenty gal tanks with hoods and filters with 5 extra bulbs for 75$. The original plan was to use dividers (solid) for 3 of the ten gallon tanks, so I would have had to use multiple heaters. I haven't seen a good divider that has small enough holes for filtration and water flow to use with fry. If someone has a suggestion as to how to make a divider that would work I would appreciate it.
The setup idea now with 4 20 gal tanks is to divide 2 of the tanks 3 times giving me the equivilant of 6, six and a half gallon tanks. I do foresee one problem with this.. Air saturation in the water since I won't have much of a surface area with solid dividers. the other two tanks will be set as grow out tanks divided in half so 4, ten gallon tanks. One of those tanks will be for keeping breeders and the other for sellers. I will be using 10 gallon sponge filters in all of the tanks for biological. I will not have charcoal as it has long term adverse affects, and using it in a line breeding system could affect quality over the long haul.
I have contemplated using 1/16th inch plexi-glass as dividers with hot pin melted holes running continuously through them. I think this would give me decent water flow for heating and filtration without making a large enough hole for fry to slip through. If you have any other suggestions please let me know.
I will be posting a picture of my new (home built) tank stand with all 4 tanks set in it. I am going to age the filters in a stable tank so help speed up the cycling process for the 4 new tanks. Thank in advance for any suggestions.
btw, I will only have guppies in these 4 tanks, and will most likely be using salt.
Total Cost so far:
$79.50 for 4 twenty gallong tanks with hood and HOB filters.
$39.20 for home built tank stand. (2X4) Will be adding birch or maple later.
Estimate $70.00 for sponge filters and pump with hose and valves. and $10.00 for 1/16 plexi-glass. grand total for complete setup is roughly $200.00 without finish wood for stand.
