The slate ones I make are 1.4 inch wide opening (3.5 cm) by 1 inch ( 2.5 cm) tall opening by about 5+ inches deep ( 14 cm) Several people have reported spawning in them already and I have only been making them for 6 months. I am glad you posted this information as it validates the dimensions others ...

Marina yes those big caves were tough to make and I am so very glad you let me make them solid. They seemed so darn large once I started putting them together and the slate piece were too big to fit on my grinders to get the flatness required for removable tops. It was very hard to get the large pie...

No problem. I spend most of my hobby building stuff and inventing new filters and tank designs. My CO2 reactors and automatic live bearing fish fry trap are my best designs I have come up with so far. I have a new river tank Idea that I think will be very nice looking, but I will probably wait until...

Yes to the fact that pumps never actually pump what they say they pump unless you are using an internal pump that does not have any friction or head loss. It is actually quite a complex equation to predict actual flow rate and most efficient pipe sizes. If you go too small on pipes then you increase...

I decided to not get the oto cats and got some Koi angels and some more species of Apistogramma instead.

Apparently the Otocinclus genus spawns a lot like the cory cats

This person is a know repeat major scammer in fish auction websites http://exoticfishfactory.com/ http://www.aquabid.com/forum/forum.cgi? action=forum&item=1123537938&category=feedback I have also heard there is one that lives in Vancouver British Columbia area that has scammed multiple people

I am unsure of the exact diameters of pipes needed. Many times where the flow restrictions are, are in bends, elbows, spray bars or valves. If I calculate 9,000 liters per hour and calculate water velocity through a 1.25 inch internal diameter pipe, I get about 625 foot per second of water flow. If ...

Oh you do mean a real sump :D I was thinking a built in system along the length of the back wall which are real neat setups but expensive. If your sump has trouble with the flow rate you can increase the diameter of the intake pipe and increase the overflow ability. The higher you pump water from un...

I tend to quarantine every fish, so I do all treatments or observations in the first month before moving the fish to their home. We do not get the Interpret or Water life brand names in the USA as far as I know. I have seen some UK brands entering the US market recently such as Hydor. I have tried t...

Minimizing toxicity also minimizes effectiveness of the treatment for parasites. When pond owners use copper sulfate they calculate how much to add to a pond with a formula based on volume of pond and the Alkalinity of the water. I have also seen this formula passed on in university research papers....

I just have 5 zebra Plecos and nothing else in the 40 US gal tank. They tend to reside down in the final 1 foot of tank length farthest from the pump where I placed all the caves per other peoples thoughts on this site. As far as flow rates are concerned, I have heard several people say very high fl...

I have treated for ich with zebra Plecos and other Plecos ( clown loaches also) using two copper products one called "coppersafe" and another called "aquarisol" these two did not seem to create any stress at all even in my pond snails. I have used another copper product called &q...

you are going to run about 2 x the circulation rate that I am running. That is a huge pump. Might be necessary if the tank you are getting is extra tall. My river tank is only about 40 cm tall 30 cm wide and 122 cm long so 6 times turnover provides so much circulation that the Plecos actually look u...

There seems to bve a bit more activity recently. I think they are still getting comfortable in their "new tank" . Every time I move them it takes them quite some time to get active again.

My experience with fraud and zebra Pleco buying. "VuFish" was the Seller and I was the winner of the first auction out of about 5 this person had going at the same time. Near the end of the thread, is my exoneration :shock: http://www.aquabid.com/forum/forum.cgi?action=forum&item=11201...
